Accounting Policies [Abstract] |  |
Basis of presentation |  | A. Basis of presentation: The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”).
Financial statement in U.S. dollars |  | B. Financial statement in U.S. dollars: The functional currency of the Company is the U.S. dollar (“dollar”) since the dollar is the currency of the primary economic environment in which the Company has operated and expects to continue to operate in the foreseeable future. Transactions and balances denominated in dollars are presented at their original amounts. Transactions and balances denominated in foreign currencies have been re-measured to dollars in accordance with the provisions of Accounting Standards Codification (“ASC”) 830-10, “Foreign Currency Translation”. All transaction gains and losses from re-measurement of monetary balance sheet items denominated in non-dollar currencies are reflected in the statements of comprehensive loss as financial income or expenses, as appropriate.
Use of estimates | Use of estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions pertaining to transactions and matters whose ultimate effect on the financial statements cannot precisely be determined at the time of financial statements preparation. Although these estimates are based on management’s best judgment, actual results may differ from these estimates. | C. Use of estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions pertaining to transactions and matters whose ultimate effect on the financial statements cannot precisely be determined at the time of financial statements preparation. Although these estimates are based on management’s best judgment, actual results may differ from these estimates. MICROBOT MEDICAL INC.

Principles of consolidation |  | D. Principles of consolidation: The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. Inter-company balances and transactions have been eliminated in consolidation.
Reclassification of prior year disclosures: |  | E. Reclassification of prior year disclosures: Certain prior year amounts have been reclassified for consistency with the current year disclosures. These reclassifications had no effect on the reported consolidated balance sheets, the related consolidated statements of comprehensive loss, shareholders’ equity and cash flows.
Acquisitions of assets |  | F. Acquisitions of assets: The Company evaluates acquisitions of assets and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or asset acquisition by first applying a screen test to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the screen is met, the transaction is accounted for as an asset acquisition. If the screen is not met, further determination is required as to whether or not the Company has acquired inputs and processes that have the ability to create outputs which would meet the definition of a business. Significant judgment is required in the application of the screen test to determine whether an acquisition is accounted for as business combination or an acquisition of assets.
Cash and cash equivalents |  | G. Cash and cash equivalents: Cash and cash equivalents consist of cash and demand deposits in banks, and other short-term liquid investments (primarily interest-bearing time deposits) with original maturities of three months or less at the date of purchase.
Restricted cash |  | H. Restricted cash: Restricted cash of $49 as of December 31, 2023, serves as collateral for the Company’s lease agreement, and $77 as of December 31, 2022, serves as collateral for lease agreements and credit cards.
Fair value of financial instruments | Fair value of financial instruments: The carrying values of cash and cash equivalents, other receivables and other accounts payable and accrued liabilities approximate their fair value due to the short-term maturity of these instruments. A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories: Level 1 - Quoted prices (unadjusted) in active markets for identical assets and liabilities. Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as unadjusted quoted prices for similar assets and liabilities, unadjusted quoted prices in the markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The following tables summarizes the Company’s financial assets subject to fair value measurement and the level of inputs used in such measurements as of March 31, 2024 and December 31, 2023: SCHEDULE OF FINANCIAL ASSETS FAIR VALUE MEASUREMENT
|  | As of March 31, 2024 |

The Company’s financial assets are measured at fair value on a recurring basis by level within the fair value hierarchy. The Company’s securities and money market funds are classified as Level 1. Other than that, the Company doesn’t have any other financial assets or financial liabilities marked to market at fair value as of March 31, 2024 and December 31, 2023. | I. Fair value of financial instruments: The carrying values of cash and cash equivalents, other receivable and other accounts payable and accrued liabilities approximate their fair value due to the short-term maturity of these instruments. The Company measures the fair value of certain of its financial instruments (such as marketable securities) on a recurring basis. The method of determining the fair value of marketable securities is discussed in Note 4 below. A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories: Level 1 - Quoted prices (unadjusted) in active markets for identical assets and liabilities. Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as unadjusted quoted prices for similar assets and liabilities, unadjusted quoted prices in the markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Concentrations of credit risk: |  | J. Concentrations of credit risk: Financial instruments which potentially subject the Company to credit risk consist primarily of cash and cash equivalents and marketable securities. The Company holds these investments in highly rated financial institutions. These amounts at times may exceed federally insured limits. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds. The Company has no off-balance sheet concentrations of credit risk, such as foreign currency exchange contracts, option contracts, or other hedging arrangements. MICROBOT MEDICAL INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS U.S. dollars in thousands (Except share and per share data) NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Property and equipment |  | K. Property and equipment: Property and equipment are presented at cost less accumulated depreciation. Depreciation is calculated based on the straight-line method over the estimated useful lives of the assets, at the following annual rates: SCHEDULE OF ESTIMATED USEFUL LIVES OF PROPERTY AND EQUIPMENT
|  | % |
Research equipment and software |  |  | 25-33 |
Furniture and office equipment |  |  | 7 |
Leasehold improvements |  |  | Over the lease period |
The Company assesses property and equipment impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the property and equipment assets, or the appropriate grouping of assets, is compared to the carrying value to determine whether impairment exists. If an asset is determined to be impaired, the loss is measured based on the difference between the asset’s estimated fair value and its carrying value. For property and equipment assets, the estimate of fair value is typically based on a discounted cash flow model. As of December 31, 2023, and 2022, no impairment charge has been recorded.
Liabilities due to termination of employment agreements |  | L. Liabilities due to termination of employment agreements: Under Israeli employment laws, employees of Microbot Israel are included under Article 14 of the Severance Compensation Act, 1963 (“Article 14”). According to Article 14, these employees are entitled to monthly deposits made by Microbot Israel on their behalf with insurance companies. Payments in accordance with Article 14 release Microbot Israel from any future severance payments (under the Israeli Severance Compensation Act, 1963) with respect of those employees. The aforementioned deposits are not recorded as an asset in the Company’s balance sheets. As for the U.S. employees, the Company has certain defined contribution plans, including a 401(k)-retirement plan in the U.S., whereby contributions made by eligible employees are matched by the Company with certain limitations.
Common stock warrants |  | M. Common stock warrants: The Company accounts for warrants issued to investors as either equity-classified or liability-classified instruments, based on an assessment of the warrant’s specific terms and the applicable authoritative guidance in FASB ASC 480 and FASB ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, or meet all of the requirements for equity classification under FASB ASC 815, including whether the warrants are indexed to the Company’s own shares of common stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.
Basic and diluted net loss per share |  | N. Basic and diluted net loss per share: Basic net loss per share is calculated by dividing net loss attributable to common stock shareholders by the weighted average number of shares of common stock outstanding during the year without consideration of potentially dilutive securities. For purposes of the diluted net loss per share attributable to common shareholders calculation, stock options and warrants are considered to be common stock equivalents. All common stock equivalents have been excluded from the calculation of the diluted loss per share for the years ended December 31, 2023 and December 31, 2022, as their effect would be anti-dilutive. Therefore, basic and diluted net loss per share were the same for both years presented. In the calculation of the basic and diluted net loss, the Company included warrants that would be exercised for no or little consideration and are exercisable with no contingencies.
General and administrative expenses, net: |  | O. General and administrative expenses, net: General and administrative expenses are charged to the statement of comprehensive loss as incurred. Insurance loss recoveries are recognized when the amount is determinable and approved by the insurance company and applied as a deduction from general and administrative expenses. General and administrative expenses, net, for the years ended December 31, 2023 and 2022, were offset by insurance loss recoveries in the amounts of approximately $281 and $156, respectively.
Research and development expenses, net: |  | P. Research and development expenses, net: Research and development expenses are charged to the statement of comprehensive loss as incurred. Grants for funding of approved research and development projects and others are recognized at the time the Company is entitled to such grants, on the basis of the costs incurred and applied as a deduction from the research and development expenses. See Note 2V below. MICROBOT MEDICAL INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS U.S. dollars in thousands (Except share and per share data) NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Share-based compensation | Share-based compensation: The Company applies ASC 718-10, “Share-Based Payment” (“ASC 718-10”), which requires the measurement and recognition of compensation expenses for all share-based payment awards made to employees and directors including stock options under the Company’s stock plans based on estimated fair values. ASC 718-10 requires companies to estimate the fair value of stock options using an option-pricing model, which is recognized as an expense over the requisite service periods in the Company’s statement of comprehensive loss, based on a straight-line method. The Company recognizes compensation cost for an equity classified award with only service conditions that has a graded vesting schedule on a straight-line basis over the requisite service period for the entire award, provided that the cumulative amount of compensation cost recognized at any date at least equals the portion of the grant date fair value of such award that is vested at that date. The Company recognizes the expense for an equity classified awards subject to performance-based milestone vesting over the remaining service period when management determines that achievement of the milestone is probable. Management evaluates when the achievement of a performance-based milestone is probable based on the expected satisfaction of the performance conditions at each reporting date. If no explicit service period is determined, the Company estimates the implicit service period based on the timing the employee is expected to achieve the related performance condition. When no future services are required to be performed by the grantee in exchange for an award of equity instruments, and if such award does not contain a performance or market condition, the cost of the award is expensed on the grant date. The Company estimates the fair value of stock options granted as share-based payment awards using a Black-Scholes options pricing model. The option-pricing model requires a number of assumptions, of which the most significant are expected volatility and the expected option term (the time from the grant date until the options are exercised or expire). Expected volatility is estimated based on the standard deviation of the Company’s closing prices according to the expected life (SAB107) for each of the grants. The Company has historically not paid dividends and has no foreseeable plans to issue dividends. The risk-free interest rate is based on the yield from governmental zero-coupon bonds with an equivalent term. The expected stock option term is calculated for stock options granted using the “simplified” method. Changes in the determination of each of the inputs can affect the fair value of the stock options granted and the results of operations of the Company. | Q. Share-based compensation: The Company applies ASC 718-10, “Share-Based Payment” (“ASC 718-10”), which requires the measurement and recognition of compensation expenses for all share-based payment awards made to employees and directors including stock options under the Company’s stock plans based on estimated fair values. ASC 718-10 requires companies to estimate the fair value of stock options using an option-pricing model, which is recognized as an expense over the requisite service periods in the Company’s statement of comprehensive loss, based on a straight-line method. The Company recognizes compensation cost for an equity classified award with only service conditions that has a graded vesting schedule on a straight-line basis over the requisite service period for the entire award, provided that the cumulative amount of compensation cost recognized at any date at least equals the portion of the grant date fair value of such award that is vested at that date.

The expected stock option term is calculated for stock options granted using the “simplified” method. Changes in the determination of each of the inputs can affect the fair value of the stock options granted and the results of operations of the Company.
Income taxes |  | R. Income taxes: The Company provides for income taxes using the asset and liability approach. Deferred tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities and the tax rates in effect when these differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. As of December 31, 2023, and 2022, the Company had a full valuation allowance against deferred tax assets. MICROBOT MEDICAL INC.

Marketable securities |  | S. Marketable securities: The Company invests in various debt securities and an equity security. Debt securities consist of U.S. treasury securities. Equity security consist of a mutual fund. The Company records these investments in the consolidated balance sheet at fair value. For all of the Company’s debt securities, the Company elected the fair value option and thus all unrealized gains or losses for these securities are reflected in the statements of comprehensive loss as financial income or expenses, as appropriate. Unrealized gains or losses for the equity security are reflected in the statements of comprehensive loss as financial income or expenses, as appropriate. The Company classifies its investments as current based on the nature of the investments and their availability for use in current operations.
Leases: |  | T. Leases: The Company determines if an arrangement is a lease at inception. Operating lease assets are presented as operating lease long-term right-of-use assets (“ROU”), and corresponding as lease liabilities (current portion), and as operating long-term lease liabilities, on the Company’s consolidated balance sheets. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the remaining lease payments over the lease term at commencement date. The Company’s leases do not provide an implicit interest rate. The Company calculates the incremental borrowing rate to reflect the interest rate that it would have to pay to borrow on a collateralized basis an amount equal to the lease payments in a similar economic environment over a similar term and considers the Company’s historical borrowing activities and market data in this determination. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which it accounts for as a single lease component. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have a term of 12 months or less. The effect of short-term leases on the Company’s ROU assets and lease liabilities was not material. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. In addition, the Company does not have any related party leases.

Contingencies | Contingencies: Management records and discloses legal contingencies in accordance with ASC Topic 450 Contingencies. A provision is recorded when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Company monitors the stage of progress of its litigation matters to determine if any adjustments are required. The Company carries liability insurance to mitigate its exposure to losses, including litigation losses. The Company records the estimated amount of expected insurance proceeds for litigation losses incurred as an asset (typically a receivable from the insurer) and offset to losses up to the amount of the losses incurred when the amount is determinable and approved by the insurance company. | U.

Government grants: |  | V. Government grants: Government grants which are received from the Israeli Ministry of Economy and Israel Innovation Authority (“IIA”) by way of participation in research and development that is conducted by Microbot Israel, are received in installments as the program progresses based on qualified research spending. Grants received are recognized when the grant becomes receivable, provided there was reasonable assurance that Microbot Israel will comply with the conditions attached to the grant and there was reasonable assurance the grant will be received. The grants are deducted from the research and development expenses as the applicable costs are incurred. Research and development expenses, net, for the years ended December 31, 2023 and 2022, include participation in research and development expenses in the amount of approximately $279 and $0, respectively.
