Re: pic: MARS stretches its 4-bar
Very clever way to get your grabber to go to parallel to the ground on both sides of the robot. Did you also consider using chain with a certain sprocket tooth ratio to get the desired rotation like this four bar system does. I've always wanted to make something like that, it saves having to use another motor for that wrist joint. Great job, any chance we could get some 3d images?
