    Hey guys

    I am going down the track of setting up a 2dof rig and a servo wheel over the next year.

    I have been looking at pricing for motors and being in New Zealand shipping is kind of rough.

    I have found a company selling off 12 of these for 50nzd (25ish usd each) will this be able to drive a 2dof rig? Keep in mind I am around 105 kg.

    Basically motor and gearbox.

    Motor specs and your mass are only part of the equation, the design of the rig also plays a big part.

    You can use the likes of SimCalc to help get your head around the tradeoffs between design Vs physics: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    At 2Nm the motors you listed are likely way under powered. Something like these specs, or better, would be more suitable: https://www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html

    Rig geometry can make a huge difference but you will need some power in any case, I would not consider motors below 150W
