If it’s useful, I’ve written up a wrapper for MuJoCo Physics GitHub - klowrey/MuJoCo.jl: Julia wrapper for the MuJoCo Physics Engine
It’s very much research code in that maybe not all features are supported or there are bugs, but I’ve tried to keep it very similar to the C-API interface specified by the mujoco header files, with some Julia specific conveniences. Again, very much research code (I’ve used it to publish some RL papers and played around with some trajectory optimization), so I have not widely announced it, but have wanted to share it with interested folks. I’ll probably include the visualizer when I get it fixed up for Julia-0.7.
Kudos to @tkoolen and @rdeits for turning me onto Julia in the first place!
