    Hello, I'm very new to this community, but have some questions. I'm pretty far in designing my motion control and wheel, but what kind of motor should I use? I found one on amazon, but am not sure if it is strong enough: In addition I'm wondering do you need a motor driver or can you just use an arduino? Third question:sos:grin: Should I use a potentiometer or rotary encoder to detect the rotation of the wheel?

    Motor and gearbox selection depends on the actual design, a compact rig needs lots of torque while a traditional shoulder mount benefits from a higher ratio worm drive.

    Fortunately there are now some great tools available to help check your design, so use Motion Visualizer and/or SimCalc to help get your head around the design Vs physics trade offs:

    Well I was planning on using a belt driven system, to change the speed/torque.

    A belt driven system in many respects is like a wormdrive, you apply a different ratio, the only real potential difference is efficiency, the mechanical principle is the same.

    Use the tools available to assess your potential design and what is required to drive it at a desired performance level.

    Can these programs also calculate the motor needed for direct drive?

    The programs presume a wormdrive, the point being made though is that design and motor selection are intimately linked.

    Members can't really give advice on motors without some detail about the intended design.
