Collision Avoidance drone

Inspiration

The idea was to have the drone respond to obstacles close by.

What it does

The drone backs away from objects or obstacles within 3m.

How I built it

360 degree lidar was mount on the drone that we built and raspberry Pi and dronekit (python) was used to control the drone accordingly.

Challenges I ran into

The responsiveness of the drone to faster moving obstacles or when drone was travelling faster. The speed of drone meant the Lidar had less time to acquire proximity data so the drone can respond faster. Also had to deal with noise in the data using kalman filter.

Accomplishments that I'm proud of

Got the drone to work reasonably well

What I learned

Learnt the possible challenges involved in responsiveness window required

What's next for Collision Avoidance drone

Developing a visual system for the 360 lidar.
