The friction with the ground is greater and the load bearing of the casters is greater. Not easy to slip. Omnidirectional wheels are more flexible and fast. The above is just a matter of experience, the shortcomings are almost finished, but personally think that there is still a lot of room for improvement of the universal wheel. At present, it has really only been seen in robot competitions.
1. Regarding going up the stairs, as long as the wheel is a little bigger, going to the next little step is not a problem.
2. The structure of the universal wheel is complex, but all rotating parts use bearings. The sealing of the bearing is still good. Sand and dust are still tolerable. The biggest advantage is that using 3 or more omnidirectional wheels at the same time can achieve any direction The translation can be any complex arc movement. The installation methods are as follows:
3. Universal wheel: As long as it is based on the characteristics of the universal wheel and the decomposition and synthesis of the motion, it can be achieved. For load-bearing ability, look at the parameters of the wheels I use for competition.
