German neurobiologist Malte Ahlers (who built a Kinect-equipped humanoid robot), sent us a progress report on his omni wheel robot. What’s especially cool about this project is that Malte really delves into how such a robot works:

I didn’t want to just copy some code that I found somewhere on the internet but wanted to gain a fairly thorough understanding of the principle behind omni wheel drives. On my website I present my way of deriving and understanding the formulas for the activation of the wheels to move the platform with a desired speed into a desired direction.
