The Dead Kangaroo Fish
Update: Next one here: https://www.robotshop.com/letsmakerobots/node/2259
As a sequel to The Headhunter I wanted to try faster and stronger, to see if I could provoke some sort of "jumping like a kangaroo" - motion.. However, the nearby option I had was the back from an old RC car. And.. where the "arms" should move in sync for it to start jumping (in my dreams), the nice motor/gear/axle has diferential drive pull and that, combined with some other laws of nature, provoked the whole thing to crawl rather than jump :/
But I will have my revenge!
