156B Week 8
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
2nd iteration of prototype completed
1st test fit on Gabby w/ Prototype #2 had to be delayed because software was not working in time
Accomplishments from Previous Week
Actuation method determined from call with Sponsor (Estelle)
Hardware ordered and received (Delrin, foam, gears, fasteners, heat inserts etc)
V.2 elbow printed and assembled (Michael)
V.2. tolerance testing on wrist solution completed (Estelle)
V.2. forearm enclosure printed and assembled (Estelle)
V.2. palm, fingers, and wrist printed and assembled (Erik)
Joystick solution soldered and wired (Maris)
V.1 Bicep enclosure CAD'ed (Maris)
Preliminary power management complete solution (charger+balancer+Lipo batteries) researched and ordered (Maris)
Coding of communication between joystick & servos started (Michael & Maris)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Final CAD design of Elbow (Michael)
Final CAD design of Forearm enclosure (Estelle)
Final CAD design of Hand (Erik)
Final CAD design of Bicep (Erik & Maris)
Finish preliminary code for actuation and test fit on Gabby (05/23 - maybe) (Maris & Michael)
Start printing ALL final component designs on Dimension SST (ALL)
Start implementing power management solution (ECE)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Use ready available pulleys instead of Delrin (Prof T, in person, 05/14)
unfortunately pulleys are not small enough in OD & width to fit in enclosure (from research)
Use brass inserts for "Delrin alignment plate" (Prof T, in person, 05/14)
not small enough in OD to fit side by side on plate (very limited space)
Use teflon tubing to route tendons in palm/fingers (Prof T, in person, 05/14)
Being further researched right now (Erik)
