Re: Derivative of Jacobian
Hello, The forward kinematics and jacobian are generated procedurally and numerically within the API, and so we do not have a symbolic function for either of these that we can expose. However, you should be able to numerically differentiate the Jacobian matrix or double-differentiate the forward kin...

Re: Setting up Visual Studio projects
Sorry for the delay -- I found the issue here; it looks like CMake wasn't setting include paths for numpy properly. I've added a PR for this that should allow you to compile and run with plots -- you just need to have python >= 3.6 and numpy installed (pip3 install numpy). Let me know if this works ...

Re: Setting up Visual Studio projects
Sorry for the trouble here; I will get a fix for this ASAP and ensure this is tested better in the future. The numpy dependency is not strictly necessary for the examples, and is only used for plotting data in the examples. I can also create a cmake flag that allows the build to occur without the py...

Re: persist send of gains through c+ api
Asma, As I went to implement this, I realized I completed missed it earlier -- this is actually in the API already! This is in the Command::Settings message: https://files.hebi.us/docs/cpp/cpp-3.4.0/classhebi_1_1Command_1_1Settings.html There is an example in the C++ examples repo demonstrating this...

Re: persist send of gains through c+ api
Asma, This is supported in the underlying C API, but not the C++ one at the moment. One big-picture thought here -- in our internal development, we have found that it can be dangerous to rely on the actuator always having the desired settings persisted when starting to control the program, in case o...

Re: Converting .xacro to .hrdf
Although there is not a tool for the conversion, if you are using the HEBI xacro macros, the conversion to hrdf should be straightforward in most cases. The HEBI xacro elements are designed to closely align with the corresponding hrdf elements. If you have a specific file, feel free to list it here ...

Re: innerEffortCmd reading
FYI, v3.4.0 of the C++ is released. Thanks again for your patience -- unfortunately, this hit at the same time as some infrastructure upgrades, so the release went through more bumps than usual. Future updates should be more smooth! Additionally in the update there are updates to support Mac M1 devi...

Re: innerEffortCmd reading
Sorry for the additional delay; I wanted to give a slight status update here. We're hitting the last steps of the release process, so the full release should be out shortly, but in the meantime we have a nightly build available: https://hebifiles.z13.web.core.windows.net/download/cpp/nightly/hebi-cp...

Re: innerEffortCmd reading
Sorry for the delay -- we have the API in internal testing, and so this should be out tomorrow.
