Accounting Policies [Abstract] |  |
Unaudited Interim Financial Statements | Unaudited Interim Financial Statements The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of U.S. Securities and Exchange Commission (“SEC”) regulations. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included (consisting only of normal recurring adjustments except as otherwise discussed). Operating results for the six-month period ended June 30, 2018, are not necessarily indicative of the results that may be expected for the year ended December 31, 2018. |
Significant Accounting Policies | Significant Accounting Policies The significant accounting policies followed in the preparation of these unaudited interim condensed consolidated financial statements are identical to those applied in the preparation of the latest annual audited financial statements. |
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 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 statement of operations as financial income or expenses, as appropriate.
Cash and Cash Equivalents |  |
| C. | 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 less than three months.
Fair Value of Financial Instruments |  |
| D. | 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 the derivative warrant liabilities) on a recurring basis. The method of determining the fair value of derivative warrant liabilities is discussed in Note 8. 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.
Fixed Assets |  |
| E. | Fixed assets:
Fixed assets are presented at costs less accumulated depreciation. Depreciation is calculated based on the straight-line method over the estimated useful lives of the assets, as the following annual rates:
|  | % |
Research equipment and software |  |  | 25-33 |
Furniture and office equipment |  |  | 7 |
Liabilities Due to Termination of Employment Agreements |  |
| F. | 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 sheet,
Basic and Diluted Net Loss Per Share |  |
| G. | Basic and diluted net loss per share
Basic net loss per share is computed by dividing net loss, as adjusted to include s by the weighted average number of common shares outstanding during the year. Common shares and preferred shares contingently issuable for little or no cash are included in basic net loss per share on an as issued basis. Diluted net loss per share is computed by dividing net loss, as adjusted to include preferred shares dividend participation rights of preferred shares outstanding during the year as well as of preferred shares that would have been outstanding if all potentially dilutive preferred shares had been issued, by the weighted average number of common shares outstanding during the year, plus the number of common shares that would have been outstanding if all potentially dilutive common shares had been issued, using the treasury stock method, in accordance with ASC 260-10 “Earnings per Share”. All outstanding stock options and warrants have been excluded from the calculation of the diluted loss per share for the years ended December 31, 2017 and December 31, 2016, since all such securities have an anti-dilutive effect. The weighted average number of shares outstanding has been retroactively restated for the equivalent number of shares received by the accounting acquirer as a result of the reverse recapitalization as if these shares had been outstanding as of the beginning of the earliest period presented.
Research and Development Expenses, Net |  |
| H. | Research and development expenses, net:
Research and development expenses are charged to the statement of operations as incurred. Grants for funding of approved research and development projects 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.
Convertible Notes |  |
| I. | Convertible Notes:
Proceeds from the sale of debt securities with a conversion feature are allocated to equity based on the intrinsic value of such conversion feature in accordance with ASC 470-20 “Debt with Conversion and Other Options”, with a corresponding discount on the debt instrument recorded in liabilities which is amortized in finance expense over the term of the notes. Convertible notes with characteristics of both liabilities and equity are classified as either debt or equity based on the characteristics of its monetary value, with convertible notes classified as debt being measured at fair value, in accordance with ASC 480-10, “Accounting for Certain Financial instruments with Characteristics of both Liabilities and Equity”.
Share-Based Compensation |  |
| J. | Share-based compensation:
The Company applies ASC 718-10, “Share-Based Payment,” 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. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in the Company’s statement of operations. The Company accounts for stock-based compensation awards to non-employees in accordance with FASB ASC 505-50, “Equity-Based Payments to Non-Employees” (“FASB ASC 505-50”). Under FASB ASC 505-50, the Company determines the fair value of the warrants or stock-based compensation awards granted as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. 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 volatility of similar companies in the technology sector for equity awards granted prior to the Merger and on the Company’s trading share price for equity awards granted subsequent to the Merger. 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 to employees and directors using the “simplified” method. Grants to non-employees are based on the contractual term. 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.
Reclassification |  |
| K. | Reclassification:
Certain prior year amounts have been reclassified to conform to the current year presentation.
Transaction Costs |  |
| L. | Transaction Costs
Transaction costs incurred in the Merger were charged directly to equity to the extent of cash and net other current assets acquired. Transaction costs in excess of cash acquired were charged to general and administrative expenses.
Income Taxes |  |
| M. | 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, 2017, and 2016, the Company had a full valuation allowance against deferred tax assets.
Recent Accounting Standards | Recent Accounting Standards In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” to provide a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The ASU supersedes most current revenue recognition guidance, including industry-specific guidance. The FASB subsequently issued ASU 2015-14, ASU 2016-08 and ASU 2016-12, which clarified the guidance, provided scope improvements and amended the effective date of ASU 2014-09. As a result, ASU 2014-09 becomes effective for the Company in the first quarter of 2018, with early adoption permitted. The adoption of this standard did not have a material impact on our interim consolidated statements of comprehensive loss since the Company has not yet generated revenues to date. In February 2016, the FASB issued ASU 2016-02 “Leases” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. For operating leases, the ASU requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The ASU retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee. This ASU is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company continues to evaluate the effect of the adoption of this ASU and expects the adoption will result in an increase in the assets and liabilities on the consolidated balance sheets for operating leases (refer to Note 5) and will likely have an insignificant impact on the consolidated statements of comprehensive loss. In June 2016, the FASB issued ASU 2016-13 “Financial Instruments – Credit Losses” to improve information on credit losses for financial assets and net investment in leases that are not accounted for at fair value through net income. The ASU replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses. This ASU is effective for the Company in the first quarter of 2020, with early adoption permitted. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements. In July 2017, the FASB issued ASU 2017-11, which includes Part I “Accounting for Certain Financial Instruments with Down Round Features” and Part II “Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-Controlling Interests with a Scope Exception”. The ASU makes limited changes to the Board’s guidance on classifying certain financial instruments as either liabilities or equity. The ASU’s objective is to improve (1) the accounting for instruments with “down-round” provisions and (2) the readability of the guidance in ASC 480 on distinguishing liabilities from equity by replacing the indefinite deferral of certain pending content with scope exceptions. The ASU is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company has derivative warranty liabilities as discussed in Note 4 which upon adoption of the new standard are expected to be classified as equity. |
| N. | Recent Accounting Standards:

As a result, ASU 2014-09 becomes effective for the Company in the first quarter of 2018, with early adoption permitted. The Company has not yet generated revenues to date, and does not yet know the impact the standard may have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 “Leases” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. For operating leases, the ASU requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The ASU retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee. This ASU is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company continues to evaluate the effect of the adoption of this ASU and expects the adoption will result in an increase in the assets and liabilities on the consolidated balance sheets for operating leases (refer to Note 9) and will likely have an insignificant impact on the consolidated statements of comprehensive loss. In June 2016, the FASB issued ASU 2016-13 “Financial Instruments – Credit Losses” to improve information on credit losses for financial assets and net investment in leases that are not accounted for at fair value through net income. The ASU replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses. This ASU is effective for the Company in the first quarter of 2020, with early adoption permitted. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18 “Restricted Cash” to provide guidance on the presentation of restricted cash in the statement of cash flows. Currently, the statement of cash flows explained the change in cash and cash equivalents for the period. The ASU requires that the statement of cash flows explain the change in cash, cash equivalents and restricted cash for the period. The ASU is effective for the Company in the first quarter of 2018, with early adoption permitted. The Company does not expect the adoption to have a material effect on the statements of cash flows as the Company’s restricted cash is not expected to be material. In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-09, “Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting,” which clarifies when a change to terms or conditions of a share-based payment award must be accounted for as a modification. The new guidance requires modification accounting if the vesting condition, fair value or the award classification is not the same both before and after a change to the terms and conditions of the award. The new guidance is effective for the Company on a prospective basis beginning on January 1, 2018 and early adoption is permitted. The Company does not expect to change terms or conditions of share-based payment awards, and therefore, does not expect the adoption of this standard to have a material impact on its consolidated financial statements. In July 2017, the FASB issued ASU 2017-11, which includes Part I “Accounting for Certain Financial Instruments with Down Round Features” and Part II “Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-Controlling Interests with a Scope Exception”. The ASU makes limited changes to the Board’s guidance on classifying certain financial instruments as either liabilities or equity. The ASU’s objective is to improve (1) the accounting for instruments with “down-round” provisions and (2) the readability of the guidance in ASC 480 on distinguishing liabilities from equity by replacing the indefinite deferral of certain pending content with scope exceptions. The ASU is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company has derivative warranty liabilities as discussed in Note 8 which upon adoption of the new standard are expected to be classified as equity.
