Gutsy Jr (aka Chibi G)
Still very much in progress, but I wanted to introduce you to Gutsy Jr.
I received a trial Nova controller kit from DFRobot and had originally planned to use it in Gutsy. However, when the controller arrived, I realised it was TINY! So, I decided that I should try to design a smaller robot for it. So, I started working on Gutsy Jr.
He walks using the same motion as Gutsy. He shift his weight from leg to leg using the motion of his swinging arms.
Since the Nova has a built-in accelerometer, I'm planning to try making a dynamic walking gait that checks for when he's shift legs before taking a step. That should enable him to walk better.
I printed Gutsy Jr's feet and body using the Form-1. It was a learning experience. I found things to be a tighter fit than I expected, and I needed to file some of the parts down. I printed the arms on the Up Plus (primarily because I keep the Form-1 at the office, and I didn't want to wait until Monday).
There's still a lot to do, but I feel fired up now that I've tested that he can walk. I had some concerns since Jr's centre of gravity is much lower than Gutsy's. So, was worried whether the arms would be able to shift his weight. So, this test put my mind at rest.
Onto the next steps!! :D
(I haven't put up the STLs yet, but I will once I finish the remaining parts. The head, etc.)
