  1. LBT Q3 2007 Engineering Review ROT Rotators

  2. Highlights (Q3/2007) • BG mechanics being manufactured • Electronics design complete, boards fabbed • BG integration equipment being made • BG gear test fit on bearing (for AGW test) LBT Q3 2007 Engineering Review

  3. Open Issues • Technical • Many details still incomplete • Undocumented telescope changes • Cable chain is high risk, may be impossible • Schedule • Integration and installation delayed • No visibility on software schedule LBT Q3 2007 Engineering Review

  4. Open Issues (cont.) • Financial • Most items costing more than budgeted • Scope creep also driving up costs • Resource • Competition with other projects • Availability of telescope • Integration/install will require mtn support LBT Q3 2007 Engineering Review

  5. Progress (Q3/2007) • More design details complete • Major BG component manufacture started • Electronics design/layout nearly complete • BG integration stand manufacture started • BG lab integration to start soon • Integration and test plan in process LBT Q3 2007 Engineering Review

  6. Progress (Q3/2007) (cont.) • App board fabbed, being stuffed • SACB board done, in-house • RIM enclosure ready for fab • Reef IM VHDL code done and tested with SW, ready for test on HW • Servo code ready for test LBT Q3 2007 Engineering Review

  7. Planning (Q4/2007) • Complete design and manufacture • Complete telescope work (cable trays) • Complete and build work platform • Test electronics and software on simulator • Begin integrating BG rotators in Tucson • Build cable chain prototype LBT Q3 2007 Engineering Review
