The 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"

But I will say it's a pity it isn't working right. As a side note, your dad's hand looks really spooky in the pictures below for some reason. Like he's reaching out of the abyss, though that's probably the lighting. Unless you keep an abyss right next to your robot facilities.

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 figured I'd be able to get around it by gearing down; turns out the forces involved are strong enough that if I get it geared enough (three levels of eight-tooth to 40-tooth gears), an axle bends enough to let gears slip, and bending plastic is not a good sign. As I don't want to snap an axle, I'm leaving it alone for now...

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...
