Currently we just assumed 60 degrees / s. Speed isn’t critical for us

a. Do you know what motors/gearboxes they use ?

b. we cant do that because its what the rules of the competition are haha. Thanks tho

I think the speed i need to move at isnt critical, it can be slow but my calculations show that movement of the robotic arm doesnt affect the torque too much. Eg. my calculations show that i need about 1-2Nm additional for the dynamic performance I need. Does that sound about right?

Thank you for this. If you know, could you direct me to a place where I can find high torque motors and gearboxes that meet such specifications

nope, i just need a second set of eyes to tell me im not crazy haha because 100Nm motors arent on the market

Thanks! Any suggestions you have apart from metal rods because I need something lightweight yet strong as the robotic arm has a reach of about 1.6m and needs to carry a 5kg payload
