• Informed RRT* to plan a collision free path from start to goal position in an N-dimensional Map.
• A minimum snap trajectory generator. The segment times between consecutive waypoints are also optimised.
• Nonlinear geometric controller for aggressive trajectory tracking and hover controller
• Quadrotor Simulator

• scipy, numpy, matplotlib, rtree-linux
