Here's the preview for part 2 of the ball wheels project. The video has quite a lot of testing in it, and it'll be up for Patrons early next week.

The next Really Useful Robot video is also looking good - using depth perception from the Intel Realsense camera to drive the inverse kinematics for the arm. That video is coming up the week after.

I feel like those wheel will make it difficult to get consistent motion, I'm very interested in see how they turn out in practice

No dead spot in motion when driving in line of the axis of the small caster wheels? @James, like you said in your previous video, its a small chance, but may cause some wear translation and even flat spot on the wheel

The wheel is there to prevent the dead spot - the hemispheres and the little wheel all move in the same direction - the passive direction of the omni wheel. The driven axle moves in the other direction. So it's like 'normal' omni-wheels (with little wheels all around the circumference of a big wheel).

'In line of the axis' of the small wheel is the rotational axis of the main axle supporting the wheel.
