I require your help regarding a problem I’m encountering.
I am a beginner in robot modelling. I am designing a robotic arm for agricultural use and I am having issues with the motors. I am using Maxon motors however the calculated load torque (including arm weight is larger than stall torque of all the motors within the Maxon catalog).
The robot arm is approximately 8 kgs and is lifting a weight of 12 grams (reach=1 m).
Does anyone know why there may be an issue and if there are any possible solutions?
Will adding another motor in the base half the loads that are applied to each joint? Or should I use gears to increase the output torque?
