A node to handle data from Lidar, if the Permocar gets too close to an object it sends a stop signal.
- Topic scan as sensor_mesgs::LaserScan containing lidar scan.
- Topic vw_estimate as std_msgs::Float32MulitArray containing [velocity, angular velocity].
- Topic lidar_stop as std_msgs::Bool true if collision threat is imminent.
Parameter that can be set.
- k11,kr11 -> default 1.5, timing variables for stop time (kr11/k11^2).
- collision_threshold -> default 0.5, distant to stop before collation in meters (messed from lidar).
- t_delay -> default 0.0, delay to compensate for system delays.
