How to calculator robot arm
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 ?
@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.
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 output shaft but ideally by bearings.
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.
@waqas Take a look at the tutorial here: https://www.robotshop.com/blog/en/robot-arm-torque-tutorial-7152
Can you give me the equation that was used above !?

@Abode The equations are in the tutorial: https://www.robotshop.com/blog/en/robot-arm-torque-tutorial-7152
When are talking about the link mass is multiple by the gravity or just mass?
@Jose Carlos For calculation purchases, you should use a force, not the mass. Force = mass x acceleration (F=m*a). Acceleration in this case is gravity, so the metric units of force would be Newtons.
So, the A1 and even the M1 should be force?
