Just a few: - Not setting the robot up correctly on launch - Different “press” / “launch” technique kid to kid - Loosening / moving parts during normal handling - axles get bent - tire tread gets moved a bit - wheels get dirty / lose traction On October 31, 2016 at 4:58:34 PM, T Lapham ([log in to unmask]) wrote: I have been coaching a number of years now and seem to see the kids always have a hard time with their programs being consistent after the robot has been running for awhile. I realize battery power could be an issue. Are their any other things I could check?
