00100 JPL proposed sending a programmer here to convert servo software to a
00200 PDP-11. The period was uncertain; times mentioned were two weeks to two
00300 months. In conversion of servo software, we would give:
00400 a) listings
00500 b) documentation or consult in its preparation
00600 c) informal advice in recoding.
00700 C. Cook will be beginning then; his learning about the arm coincides
00800 conveniently with conversion to a PDP-11. It was expected that he
00900 interface as much as possible with the JPL staff member.
01000
01100 Construction of a duplicate of the arm has been conservatively
01200 estimated as a 6 month project, with appropriate safety factor, and
01300 assuming priority. We are not organized to manufacture and deliver
01400 an arm. We can communicate with and advise a JPL engineer as
01500 follows:
01600 a) drawings for arm, hand, and electronics
01700 b) parts list and sources, details of machining bid
01800 c) informal advice for assembly.
01900 An attempt should be made to maximize information transfer and
02000 minimize diversion from our research.
02100
02200 An alternative which cannot be counted upon, is to license production
02300 of the arm. It is now likely that we can license complete
02400 mechanical construction and assembly. Fabrication of electronics is
02500 completely unexplored.
02600
00100 As the basis for discussion of a proposal, it is essential that we
00200 not be closely tied down to a fixed project. We must be free to make
00300 changes as necessitated by laboratory considerations. We have
00400 demonstrated the capabilities of the lab, and what our plans are; if
00500 these are useful to NASA, that would be the basis for a contract. A
00600 presumption is that while we may produce demonstration systems,we
00700 will not deliver any systems for NASA.

01800 A minimal system might assume that we build the necessary PDP-10 to
01900 PDP-11 interface, and A/D and D/A channels. That is probably
02000 straightforward, but we can't guarantee that we won't encounter
02100 problems.
