High Speed Quadrotor flips Learning

Installation

pip install -r requirements.txt

Running

The multi_flips.py script can be used to perform cmaes optimization or generate matplotlib flight plots or generate data for blender.

usage: multi_flips.py [-h] [-f [F]] [--fly | --cmaes | --blender]

Quadcopter multiflips

optional arguments:
  -h, --help  show this help message and exit
  -f [F]      Parameters file to generate output
  --fly       Plot the flight
  --cmaes     Run cmaes optimization
  --blender   Generate data for blender
 
--fly and --blender take a file as an argument that can be used to provide optimized parameters (Ex: example.params).
If the file is not provided default initial parameters will be used.

Matplotlib Plot

Using --fly will generate a matplotlib animated plot as below

Blender Animation

An animated plot using blender can be generated by the following steps

Generate the data using --blender -f example.params
Open quadcopter.blend in blender and paste render.py into blender and set the appropiate path for the state data quaddata.npy file generated in the first step in the code pasted in to blender.

Example Output: Blender Flight Path Video
