Project plan

Design types developped:

✔️ Linear Control

⬜️ Lyapunov-Based Control

⬜️ Model-Based Predictive Control

Handle Obstacles:

⬜️ handle unknown obstacles in the trajectory seen by the perception sensors

⬜️ Add dynamic reconfiguration

⬜️ Add others methods to generate trajectories

Launch

1. NODES

1.1 trajectory_controller

This node provides an implementation of a trajectory tracking controller through a ROS Action Server. Given the action goal, this node computes the velocity commands to move the robot from an initial point to a goal point.

1.2 reference_states_server

This node provides an implementation of the ROS Service Server that computes the reference states (position, velocity, and acceleration) of a trajectory given a path, the average velocity desired, and the sampling time. The reference trajectories are generated using Cubic B-Spline Interpolation.
