Hi Elizabeth, (...) there is an 8ms cycle, and the motor is on for a part of that: 1ms for power level 0, 2ms for power level 1, up to all the 8ms for power level 7. The rest of the time the motor is floating, i.e. the motor inputs are disconnected, (...) (20 years ago, 13-Mar-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

(...) PWM--Pulse Width Modulation. Basically, during a cycle, power is turned on and off. The lengh of time the power is on is the pulse width. Longer pulse widths corispond to higher power levels. This cycling is supposed to happens fast enought (...) (20 years ago, 13-Mar-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

Hi I am curious how the power levels are being implemented. I am not talking about the icon level navigation. How the motor actually adjusts to the different levels setting? Gear slipping? Thanks in advance... -- Elizabeth (20 years ago, 13-Mar-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)
