I've decided to make Groucho into a two-wheeled balancing bot. This would make him 5' tall at least and 2 wheelchair motors will give him enough torque.
However, because I don't want to make Groucho-sized holes in the wall or destroy Groucho by ramming him face first into the basement concrete floor, I'm going to do a test case first.
My plan is to create a 2' tall, 3" deep, and the width of a long breadboard plastic frame. If I can, I will get it laser cut from acrylic and if I can't I'll cut it out the hard way.
For motors I have a bunch of used Dynamixel MX-64 robot servos, I'm hoping that two of them are strong enough, otherwise I'll have to use other motors and I only have one set that is probably too long for this and I don't want to buy anything new for this.
If this pans out and doesn't self-destruct, I'll put the plans and software up as open source. And maybe make a kit if people are interested.
Have a nice day!
