My focus for the past 8 years is been with VRC but I was recently teaching elementary students the fundamentals of Vex IQ. We had each student build a push bot with two motors and then held a mini competition.
What I noticed was that the motors don’t seem to accelerate in a very linear progression. The light weight bots seemed to sit still until the controller sticks were at about 80%. This made driving pretty difficult as it was either stopped or full speed. I plan to test this more but I thought I would get your thoughts on my issue. Have you been able to gradually change speed with your IQ bots?
The IQ brains have the latest firmware, charged batteries, and are a very basic push bot with two motors.
