Re: Teach_repeat armApi
Can you check what version of `hebi-py` you are running? This feature was added in version 2.2.0, and I did confirm it working on the latest hebi-py 2.3.0.

Re: video of 'Teardown: HEBI Robotics'
Hi! The teardown was part of a course done at Northwestern a few years ago. I'm not aware of any videos or public material other than the pdf presentation.

Re: How to configure feed_backward in PID
You can "disable" the effort feedback portion by only using the FeedForward term (=1) and setting Kp,Kd,Ki to zero. This way the torque controller serves as a unit conversion from actuator specific units to Nm/rad.

Re: Command Strategy in Python Script
This is likely related to the command lifetime. By default, APIs send a "life time" (a user specified timeout) of 250ms, so sending a single command would result in a small movement and almost immediately turn off. You would need to send commands in a loop. This feature prevents unpredictable/harmfu...

Re: Communication between Matlab API and Simulink
Simulink targets are unfortunately really limited, so it's not possible for us to create a real Simulink API.
If you can't use an I/O board as Dave mentioned, you would need to send the Simulink data to your MATLAB instance via a UDP block.

Re: Error in code for ex_kinematics_visualization.m
I've just confirmed that the current examples master branch https://github.com/HebiRobotics/hebi-ma ... /kits/arms works for me without issues.
Is it possible that you have local modifications? Can you try checking out another (clean) copy of the examples repo and try it again?

Re: Large Error in feedback velocity and irregular feedback effort for actuator
Hi! Sorry that you're having problems. If possible, please record a log file of the operation using Scope and share it with our support email address (support at hebirobotics.com).

Re: Command Lock X series Actuators
The lock-out gets set by APIs and is limited to maximum 5 seconds per message. You likely have some other process or other computer running that is actively sending commands to the actuators. APIs send commands with a maximum lifetime that sets an expiration time. It exists for two reasons: While a ...

Re: Actuator changed its absolute zero angle
Sorry that you're having problems. There is a parameter in Scope that lets you adjust the internal reference point. Maybe someone set it by accident? You can get to it by enabling the "Params" mode on the Dashboard tab. https://docs.hebi.us/resources/scope/dashboard_reference_points.png You can offs...
