Construct robotics & automation programming for practical uses

construct a simulation that have THREE (3) robots running simultaneously, one robot displays a LEADER with random-turn behavior and another two robots have FOLLOWER behavior using LiDAR scans, i.e. following the nearest detected object in-front. The leader robot have a restricted random-turn, i.e. only can turn within the front range of the robot, from 45 degrees to the left and right directions (0 is the front of the robot).
