 Inputs to the MATLAB program consist of the position and orientation of the robot and data from the LIDAR sensor. Outputs from the program controls the linear and angular velocities of the simulated robot base wheels to perform a specified task. A Finite State Machine (FSM) manages the sequence of robot behaviours, e.g. initial, moving forward, stopping, moving backward.

 ## Project 1
 
 - Straight-line trajectory generation
-- Moving along a circle trajectory with constant orientation
+- Moving along a circular trajectory with constant orientation
 
 The robot motion is generated by using proportional regulators with limited output.
