Lots of progress today!
The prototype chassis is ready for some code and an electronics board! We finished mounting the transmissions and putting chain on and also mounted the motor for the ramp release mechanism! Kersten and I also rigged up a battery mount for the prototype chassis made out of good old wood and angle iron :)
Thanks again to Jim for the hollowed-out Delrin "chain tensioning" rods and for taking Kersten, Chrissy, Anne, and Melissa to the shop to help us:
-Cut chain to length
-Get some polycarbonate for the electronics board (if any of you programming/electronics people are reading this, all you have to do is mount your stuff onto this sheet, which has already been cut to size)
-Mill a slot for a key in the arm shaft
-Drill holes for set screws in the transmission sprockets
-And probably other things I'm not aware of since I didn't go
Meanwhile, Nandini learned about putting chain together with half-links and master-links. yay!
See you all tomorrow at 11:00 (get ready to work on the arm and the crate)!
ps--PLEASE reply to my email re Portland by tomorrow (Sunday) afternoon if you haven't already!
