Assistance with Mecanum Wheels

[Urban Hawk]

I couldn't find the information exactly, i don't know where it went to. However mecanum wheels can hit high speeds, probably higher speeds then normal wheels since due to the rollers generate less friction while moving (the tend to produce more horizontal friction which allows them to turn like they do.) I know we hit between 10 - 15 mph with our robot last year and it had mecanum wheels. As for suspension i would say its a must regardless of what type of wheels you use if you don't want to wreck your robot like i did to ours last year due to no suspension.(destroyed entire floor, snapped the 120 pound tested fishing wire we were using for lift and it wrapped around the axle of one of our wheels and caused considerable damage. It wasn't a pretty sight. That and the time when we crashed into the cafeteria wall at full speed, knocked a few tiles of the wall and bent the axle.) Point is... regardless... put the suspension on!
