Go to Post Whether or not you use wheel weights, if you're running a wheel at several thousand RPM, you'd better have an effective containment system to protect the outside world in case something spontaneously disassembles itself. - Alan Anderson [more]

Ohh, I see. Thanks.

That's seems like a very logical and feasible idea.

Very easy to C & C and only requires assembly. When we complete the drawings we will post them. The drawing that we have posted is only missing two parts but is pretty much completed. We will take that assembly and make four units and connect them at the omni wheel with an axel. To attach them to the robot we will have two steel tubes that a drive side will slide onto and then the bumper bolts will slide into the tube and two cotter pins will hold it all together. We have tried to make it simple so the student can understand what they are assembling and can make repairs when needed.
Complexity isn't just how many parts have to be made. You could use all COTS components and still have the most complex robot out there. This design is inherently more complex than a 6wd or a 4 wheel mecanum (the two most similar designs). Also, the pivoting frame throws a huge curveball when considering mounting manipulators.
