I like this robot competition, I created another model, I really like the shapes and lines of the Honda Asimo robot, so I tried to model one as best I could.
I used 4 different types of movable joints in the model - vertical, horizontal, rotating cylindrical. Now I enjoy creating movable models printed with Print-in-place.
I managed to move my handle easily, if there is a problem, let me know

The robot figure is printed Print-in-place, the battery is separate, it is inserted into the holes on the back

Small update! Adjusted palm shape
