Velocity control mode acceleration about xarm-python-sdk

[penglongxiang]

Hi, if set_tcp_maxacc still can not make a difference, I suppose it would be the jerk (derivative of acceleration) being low (for stable and smooth transition), however, its value for velocity mode is fixed currently, we will test and increase it in next controller firmware updates. May I know what is your target linear velocity and expected time to reach it?

Thank you for your answer!
Maximum possible acceleration and jerk would be the best in our case .
We would expect the arm to stop completely within ~40 ms. Sure, maximum speed to meet this requirement depends on maximum acceleration possible.
If jerk and acceleration could be configured in velocity control mode just like in position control mode we would really appreciate that!

Hello!
Do you know when this feature is going to be implemented? Should we wait or it is not planned for release?

We are in the process of optimizing it, could you tell us 40ms is from what velocity to decelerate and stop? I think it is relatively harsh for a high speed.

Will set_state(4) directly be suitable for your case?
