I have managed to get the WiiMote to control my RoboNova.
Check it out:
It is a very basic implementation and still a bit jittery - but serves as a proof of concept. At the moment each WiiMote only controls only one shoulder servo – but there is no hurdle to using more servos (I just have not had the time yet to program the RN1 accordingly).
Looking forward, I think the limiting factor will be the configuration of the Robonova arm servos and the lack of a yaw sensor on the WiiMote – I will have to rely upon the thumb direction controller for directional walking.
