A shared roller bracket and limited second shaft reduce roller gap, shake, noise, and vibration for more stable omni wheel running.
By reading magnet drive output during wheel rotation, the robot confirms surface adhesion without visual checks or prior surface data.
Raised traction elements on independently rotating wheel rollers improve grip and odometry on soft surfaces without adding high stress or power demand.
A locked second shaft and dual-roller bracket reduce roller shake, noise, and vibration while improving omni wheel running stability.
