         RE: REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

         We have examined the Registration Statement on Form S-3 to be filed by
Adept Technology, Inc. (the "Company") with the Securities and Exchange
Commission on the date hereof (the "Registration Statement"), in connection with
the registration under the Securities Act of 1933, as amended, of up to
6,244,447 shares of your common stock (the "Shares"), 131,978 shares (the
"Hexavision Shares") of which are authorized and have been previously issued to
the selling shareholders named therein in connection with the acquisition by the
Company of Hexavision Technologies Inc., and up to 6,112,469 shares (the "JDS
Shares") of common stock which may be issuable upon conversion of 100,000 shares
of convertible preferred stock of the Company. The Shares are to be offered by
the selling shareholders for sale to the public as described in the Registration
Statement.

         As your counsel in connection with this transaction, we have examined
the proceedings taken and proposed to be taken in connection with the sale of
the Shares. It is our opinion that, upon completion of the proceedings being
taken or contemplated to be taken prior to the registration of the Shares,
including such proceedings to be carried out in accordance with the securities
laws of the various states, where required, that (i) the Hexavision Shares are
legally and validly issued, fully paid and nonassessable, and (ii) the JDS
Shares, when issued in accordance with the terms of the Company's Statement of
Preferences and in the manner referred to in the Registration Statement, will be
legally and validly issued, fully paid and nonassessable.

         We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, including the prospectus constituting a part thereof,
and any amendment thereto.

                                            Very Truly Yours,



                                            /s/ Gibson, Dunn & Crutcher LLP
