The Robot Torque Arm Calculator is intended to help you choose the right motor for each joint of your robotic arm. The torque (T) required at each joint is calculated as a worst case scenario (lifting weight at 90 degrees). Ensure your units are consistent. Most common units are …

@pieter Not sure what you mean.

thanks a lot.how to calculate the torque for a cylindrical robot arm which has one rotary and 2 linear joints

@aishwarya poojary Can you create a new topic on the RobotShop Forum and include an image or drawing of the setup?

Please How accurate is that calculations ?

Very insightful. Do you have any ideas about a program that can calculate the torque required to actuate a joint? Thank you.

@Bruno Akinjide Orisanaiye We do not have a specific program, but it’s all a question for force times distance.

please explain how to calculate the required torque for base rotation

@Zeeshan The base rotation only needs to resist inertia and friction. Both of these tend to be hard to calculate, but also relatively low. We do not have any particular method to suggest at this time, but ensure the weight of the arm is not supported directly by an actuator’s out…

@Khaled Refer to the tutorial to see which assumptions were made. This is a “worst case” scenario where the arm needs to support an object at maximum reach.
