Video?

Can you post a video to see how the legs move?

MiPosaur

Spotted the black velociraptor (MiPosaur) on the shelf. I like raptors too and have always wanted the wearable kitrex costume to be commercialized. Guessing you might have WowWee’s raptor somewhere too?

Thank you for your interest!

If I find a way to test it at this stage, then I sure will!

Indeed I do! I had started
Indeed I do! I had started to hack it, but when I realized how hard proper hacking was, the project’s been put on the back burner…

Maybe someday when I’m ready I’ll finish hacking the RoboRaptor and hack the MiPosaurs, too. Then I’ll have my very own raptor squad!

Some time back Jim

Some time back Jim Demello posted an article on his DuckBot. It walked (waddled) by shifting the center of gravity by moving the neck from side to side while rotating the leg joint. I have tried to duplicate his project with zero success. Went so far as to purchase a laser etcher/cutter to precisely cut the body parts. Yours is a much more adventurous endeavor. Any thoughts on how you might enable a gait?

I was thinking of first
I was thinking of first making the bottoms of the feet a little flatter and bigger to aid balance- ironically, by adding a little more material to them, like maybe cardboard. Now that I think of it, I’ll do the same for the legs, to make them a little sturdier. Afterwards, I’ll add the tail and the front of the skeleton, which might help with the center of gravity. Finally, I’ll try to have the tail move side to side opposite the leg that is being lifted, to help even more with balance.

This is going to take a lot of effort, I’m sure!

Gait

Perhaps also moving the neck. If the feet are at a slight angle when you do tilt to the side it might help balance on one leg. 

I suspect that the legs and hips are going to need a lot of structural support. 

Do you have the source design files? Adding servo mount holes rather than glue might help while experimenting.

Moving the neck also and
Moving the neck also and putting the feet at an angle sound like good ideas. And I do indeed have the source files, so maybe I can re-print with servo mount holes.

Thank you for your input!
