Re: Trajecotry generator gives an error on getStartTime()

Sometimes MATLAB has issues with loading Java libraries after other Java have been executed. Did you try restarting MATLAB and running just this snippet? If that fixes it, you may need to pre-load your other dependencies first. Here is some more info: https://github.com/HebiRobotics/MatlabInput#warn...

Re: Periodic drops in connexion with actuators

Hi! Networking issues can be caused by a number of reasons, ranging from issues on the computer side to faulty Ethernet ports or bad cables.

If you can take a log file in Scope and send it to us via Email (support@hebirobotics.com) we can likely narrow it down and help you with the debugging.

Re: feedback frequency and getNextFeedback

Sorry for the late response. For some reason we didn't see a notification about it. 1) Both F1 and F2 run concurrently in separate OS threads 2) Workflow: a) F1 sends messages requesting feedback. This also increments the sequence number and sets the "pc transmit" timestamp. Afterwards, F1 goes to s...

Re: feedback frequency and getNextFeedback

getNextFeedback always returns the latest state or blocks until a new state is available. If F2 is slower than F1, it will end up skipping some measurements rather than adding lag by buffering.

The only exception to this are offline log-groups where getNextFeedback always advances by one.

Re: Changing name/family on Android

Swiping in from the left edge brings up a name changing menu. You can also change it using Scope.

Re: Problem with gravity compensation

Hi! Before debugging this we'd like to verify that there are no hardware issues. Please send a log file of you running the demo to support@hebirobotics.com. The easiest way to record a log is from Scope: Get Scope https://docs.hebi.us/tools.html#scope-gui Select the relevant devices Click "start log...

Re: Daisy URDF file

Hi! We are in the process of rolling out hrdf with tree support and will update the kit files once all APIs support it. Here is an initial version for Daisy: https://github.com/HebiRobotics/hebi-matlab-examples/blob/master/kits/daisy/hrdf/Daisy.hrdf The URDF converter unfortunately does not support ...

Re: Converting .xacro to .hrdf

Hi! Going from hrdf to urdf is unfortunately a lossy conversion, so it only works one way. The easiest ways to create an appropriate hrdf file is to do one of the following: 1) visually build the configuration at https://robotbuilder.hebi.us/ and click "export" in the bottom right corner 2) adapt ex...

Re: Units for Command functions (position, velocity, effort)

The APIs also support linear stages, so we decided to make the units agnostic. However, you are not the first one to be confused by this, and we are actively thinking about changing the units to rad, rad/s, Nm, and potentially changing "effort" to "torque".
