The (original) idea was to have a simple and lighter transmission by not having to include an extra gear reduction for the small CIM's (5000 rpm) by working around the large CIM (2500 rpm). In practice we quickly found out that that this was the wrong approach, as it is lacking in acceleration and agility. There was no time or space to include two small CIM motors in the robot by ship date.
Live and learn.
This is our first year with a two-speed transmission, and one of many lessons. Next year expect two motors per transmission, as well as a lighter, smaller, and more simpler design.
