Another post is up, about the propel system this time!
I have this idea that the ball will be driven with a motor and a small wheel inside a bigger ring, with a friction wheel underneath.
Sorry for my bad sketch
I have not yet tested this concept but it should work, at least it does in my head! 😉
The friction wheel underneath will be pressed against the ring with some kind of spring tension, haven’t figured out that part quite yet though.
Here’s a screen dump on the propel ring taken from FreeCAD.
The brown and red parts are removable for easy
fitting of the motor/steering platform
There will be a ring and a motor with wheels on both sides of the ball to minimize torsion of the platform.
I have tested the motor with ESC and it runs nice and smoothly. Next will be to draw the motor- and friction-wheels and then make an IRL test of the propel system.
Stay tuned! 😉
