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 …

@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 ?

@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.

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.

@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…

thanks a lot.Is this torque useful for industrial design?I want to build industrial robot arm and in want to choose my servo motors. can this help me?

@mohammad The calculations here are a bit simplified, but yes, the calculations can certainly give you an idea of the torque you will need at each joint in order to hold the arm at full reach.

@Coleman Benson , I want formulas for the torque calculation. I am making robotic arm (5 dof). and I don’t know how to calculate torque of base.

please explain how to calculate the required torque for base rotation
