Not sure if this could help (and sorry to be so late to found this, only now)...maybe the robot could point his left (or right) arm to the camera, and push forward to take the speed up...(problem will be the legs too, which look too static as well...and need some fixes...).
If it is doing some super speed ?
But I totally understand if you can't do this...it probably needs a lot of time to manage all these fixes...
Your character look nice in the middle of this ^^
