Re: Running Scope alongside APIs

Absolutely, that is the way Scope is intended to be used.

Scope is designed to run in conjunction with anything you may be doing from the API, from either the same or a different computer. The plotting tools in particular are an extremely useful tool for online configuring, tuning, and debugging.

Re: Which API should I use?

It depends. It is probably best to start the with language you are most comfortable in. If you are just starting out in programming, the Python API is probably a good starting point. If you are at a school or company that has access to Matlab, the Matlab API can be useful. The full list of supported...

Re: Spring stiffness

The stiffness of the actuator depend on the model and hardware revision. X-Series Actuators prior to early 2019 The stiffness is approximately linear and ranges from about 70 Nm/rad to about 170 Nm/rad. Details are provided in the hardware documentation . This applies to hardware revision A9V/B9V/C9...

Re: Actuator certifications

We have certified the X-Series and R-Series actuators for FCC part 15b testing as well as the CE Mark testing for EMC and ESD.

We do not currently have any UL certifications.

Re: Temperature rating

The actuators can run at ambient temperatures up to 50º C. The actuator will have decreased performance at these temperatures, but it will not overheat or shut down. Above this temperature the electronics may shut down due to temperature limits. The internal temperature of the electronics, along wit...

Re: Housing temperature when running

The housing of an X-Series or R-Series actuator can theoretically get to about 80 deg-C at near the motor if the module is stalled at full power for several minutes. In our testing here we have seen the housings of an X8 actuator get as high as 65º C.

Re: Actuator command/feedback rate

You can command up to 1kHz, although for our typical applications we control the actuators at around 100Hz. In general with a controlled wired network, the command and feedback rates are limited by the OS you are running. From macOS / Linux you can get reliable communication up to 1 kHz. On Windows ...

Re: Sensors in actuators

There are number of sensors in the X-Series and R-Series actuators. This includes feedback related to motion control like output position, velocity, torque, IMU, motor winding temperatures, voltage, current. We also provide a large amount of additional feedback like hardware timestamps, the status L...

Re: Control bandwidth

The actuators have a roll-off frequency of about 5-30Hz, depending on the model of the actuator, the gains that set on the actuator, and the details of the commanded motion. Bode plots of the actuators under different load conditions are available in the hardware documentation: http://docs.hebi.us/h...
