Description The Pure Pursuit block computes linear and angular velocity commands for following a path using a set of waypoints and the current pose of a differential drive vehicle. The block takes updated poses to update velocity commands for the vehicle to follow a path along a desired set of waypoints. The pure pursuit algorithm consist of the following steps: Get vehicle's current location Look ahead and identify a goal point Compute a curve and steering angle to the goal point Move towards the goal point following the curvature set by the steering angle Go to step-2 Pure pursuit steering suffers from 3 common issues.
