Software architecture corridor challenge
Initially, six functions are to be written to perform specific tasks to complete the corridor challenge.
Function: const_hard
Description: Stop Pico from running into a wall by readjusting if any point in the laser data is under a threshold.
Input: laser data
Output: cmd_vel
Syntax:
Function: readlaser
Description: Reduce the set of laser data to a managable set of variables by only taking the the data from the front, sides and back (from the frame of reference attached to Pico).
Input: laser data
Output: laserfront, laserright, laserback, laserleft
Syntax:
Function: sit_eval
Description: Use the laser data to determine the situation the robot is currently in, corridor (1), T junction left (2) or T junction right (3).
Input: laserfront, laserright, laserback, laserleft
Output: sit_number
Syntax:
function: corridor
Description: sit_number = 1, attempts to stay in the middle of the corridor and continue straight on.
Input: laserright, laserleft
Output: cmd_vel
Syntax:
Function: t_junction_left
Description: sit_number = 2, drives a set distance forward, turns left and again drives a set distance forward.
Input:
Output: cmd_vel
Syntax:
Function: t_junction_right
Description: sit_number = 3, drives a set distance forward, turns right and again drives a set distance forward.
Input:
Output: cmd_vel
Syntax:
