Subject: [alt-beam] 8 motor Spyder
Hey Ian, glad I checked out your page! I would have kept putting the 240 in
backwards on all my non working bicores! Hehe! Thanks! (:
I regret pulling the external plastic gears on all my BG Micro motors! I got 8
more, so I'm going to use them for the legs on my 4 motor spyder. The extra
torque will help alot. I'm going to make the legs capable of lifting to the
height of the bottom edge of the robot's body, at least. Maybe higher! I want
the bot to have a high mobility with long leg strides. I'm wondering if it's
better to have extending legs or rotating legs. The extending legs would each
face out 90 degrees from each other at a fixed angle (it could vary I guess).
There would be two vertical joints each with their own motor. The rotational
option one would have a motor operate the knee and hip together lifting and or
extending with one motion, and the rottional motor would swing the leg
horizintaly. Does anyone know which method is better? I'd use both together, but
I have a limited supply of motors (or rather, my many motors reserved for other
bots! Hehe! :)
Any recomendation as to what design is better?
