My team is strongly considering Mecaum this year. However, we are a little concerned about the 4 inch high steel barrier. We did some tests and our 8 inch mecanum bot can go over the barrier without too much problem. However, we are a little concerned about if the mecanum wheels will get worn out over time. The wheels are delicate and ramming into the 4inch high steel barrier can't be the best thing. We might go for 10inch heavy duty mecanum wheels but would either set of wheels get worn out considerably?
