frustratedThe robot, as I have it designed, won't work; the motors just aren't strong enough to lift the arm. I knew it would be a problem, but I didn't realize exactly how much force was involved;
hence, I'm changing the design totally. I'll have to make it a side-pincer thing, which is pure hell to mount on a Roverbot base.
hmm.
At least the NQC program I wrote should work on both designs...
Don't worry, I won't say "I Told You So"
And it's a darn shame it isn't working right; it LOOKS very cool. Hopefully you can come up with something that will work by Christmas!
Re: Don't worry, I won't say "I Told You So"
I'm having trouble getting the pincers mounted, for the reasons I expected. The Roverbot chassis is great for modularability, but only if the attachments don't require motors.
Hmm. Maybe I should work the motor into the drive base and use a pulley attatched to a right-angle gear pair to get the force to where I need it, since I can't reasonably mount the motor on the front...
