yay to anne for picking up my blogging slack!
it’s been a while. yeah. sorry. hopefully i’m back for good now.
well, with 12 days to go, we’re in pretty decentish shape!
we have a chassis with four wheels and four gear boxes (yay for easier chain tensioning!). it sort-of kind-of drives. as in, it drove on saturday with emily’s funny button-pushing code.
the code in the debuggingblahblah folder does NOT really work when downloaded. the speed controllers do the blinking dance. BUT we are “in the loop.” so maybe the pwms are getting overwritten by some default code crap?
BUT when we downloaded emily’s code from saturday, three out of four wheel moved and speed controllers were steady state. we determined that there is one unhappy (and so labeled) speed controller, which prevented the last wheel from moving.
coding’s… getting there. we have one file (drivingoffcases.c) that has a buuuunch of functions and our two large case statements. we still need to write the part that talks to the pwms and then the drive_routine function which will bring them all together. also, uh, remember to reference all that in user_routines.c. it doesn’t miraculously do that by itself. we’ll continue work on that.
oh, our basic plan: the joystick axes will be y for fwd/bwd and x for turning (although i don’t know if we can actually turn – we may only be able to spin. hm). and then the aux buttons will let us SLIDE!
build: i think they’re getting there on an actual real gripper/tower design? i don’t really know details. i heard something about jimmy welding soon, though, so that’s definite progress!
yay for doug for getting the bad tether fixed, and the autonomous box (i know ginna was working on that with him in the ee lab today) and working some serious magic on the gts resistors generally being cool like that.
thanks to karlin and jessa for programming awesomeness
and jimmy and emily for always awesomeness
and ginna’s family for the awesome sandwiches
i need some awesome sleep…
