Motor Speed to Robot Speed Calculator

Motor Speed to Robot Speed Calculator

In these CoVid-19 days it looks like we will share more articles, projects. I am starting with one basic calculator for robot speed. You can easily calculate it with a calculator though, but laziness .. 🙂

Try changing values below with your motor’s values.

For instance we are making one example of old JSumo Robot:

Motor is Maxon RE35:

  • Nominal Voltage is 15V
  • Nominal Speed is 7070 Rpm
  • Applied Voltage is 6S Lipo 25.2V
  • Gear Ratio: 4.3:1
  • Wheel Diameter 38mm

With these informations, it is giving me whopping 5400mm/sec speed! Sure this is free speed and nearly half of speed is lost in sumo robot projects due to high magnet and friction forces.
