ICC -Instantaneous Center of CurvatureAxial RotationRoboVITics(The Official Robotics Club Of VIT)Increasing the speed of the BOT If you want to make a speedy robot, then a wheel of a relatively large diameter should be used. This is because the motor gives a fixed rpm and to increase the linear speed, we need to increase the diameter. Since v=*r, where = angular velocity (rpm) , v = linear velocity and r = radius. So, to increase v, we need to increase r because is constant for a particular rpm motor
