This is Little Robot. I did educational videos about Little Robot at https://pistonrobot.com. I made these videos to show (in little steps) that anyone can use SketchUP to make a pistonrobot. Whew ! These educational videos are on YouTube, named: Pistonrobot Little Robot Part xx (where xx is the number of the video. Currently there are 27 videos.)
This Little Robot is updated again, I got the thorax so it can rotate, and I improved the ankle (I think, tell me what you think). Both ankles are done now I am working on movable 2 front toes and a movable heel ....whew, so little room we'll see.
