Re: The DH parameters of the UR5

I also encoutered this challenge when I used 4.7 version.But I extracter the DH parameters from coppeliasim which is diffrent from the data in UR official website.Can I know now have some way to solve this problem.

Re: How to correct DH parameters

Is there a specific solution? I've been troubled by this issue recently because I feel that the theta value of the DH parameters in CoppeliaSim is not zero when the robotic arm is initially placed in the scene.

Re: modify the DH parameter

I extracted the DH parameters through this method. Why are they different from those obtained from the UR official website? And the difference is quite large.

The UR's DH in coppeliasim

I attempted to write a forward kinematics program, where the DH parameters were extracted from the UR official website. However, the calculated coordinates are different from those in CoppeliaSim (I placed the robotic arm at the origin of the coordinate system, and each joint angle displayed in ...

Re: Forward Kinematics with DH parameters

I have the same problem. May I ask how you obtained the DH parameters of the UR5 in CoppeliaSim? I tried to write the forward and inverse kinematics myself, and they can verify each other now. However, when I apply them in CoppeliaSim, there is a significant difference. I don't know why. Could it be ...
