I am part of my college robotics team which is preparing for Robocon 2017.
We have used Mecanum wheels in last Robocon competition, but we have faced huge slip and vibration. I have looked for all kinematic and dynamic formulas and all stuff about Mecanum wheels, but still can't get to a conclusion for my problem.
The robot is around 25 kg and the Mecanum wheel diameter is about 16 cm with 15 rollers (single type). Please help me why it happened like that!?
Also suggest me what to do now - Should I design a new Mecanum wheel or bring it from market?
If I should design, what parameters should I consider, and please help me how to design in CAD software like SolidWorks? And then, shall I give it to 3D printing?
If I should buy directly from market, where should I buy?
