Checkout the examples folder for usage examples.

To run the dodge ball example, run the following command

include("examples/dodge_ball.jl")

You should see the visualization below:

To run the dodge ball with end-effector goal example, run the following command

include("examples/dodge_ball_maintain_ee.jl")

You should see the visualization below:

To run the cornhole example, run the following command

To run the package delivery example, run the following command

include("examples/package_delivery.jl")

You should see the visualization below:

The initial run of each example may have a delayed startup of the mujoco-python-viewer and other intermittent delays in-between simulation, due to the Julia pre-compilation process. If the interface asks, click Wait, and it may take up to 30 seconds to run. After the first run you should no longer have any delays.
