RGB Swarm Robot Project E-puck Code (outdated)

This page documents the e-puck code for the RGB Sensing Swarm Robotics project. The code on the e-puck was written in C and compiled using Microchip's MPLAB C Compiler for dsPIC DSCs (student version).

This code is a branch of the Swarm Project E-puck Code.

Tasks

Complete

• Restructured code to make more modular.
  • Split dsPIC_XBeePackets and wheel_speed_coordinator into h and c files
  • Pulled packet assembling code out of main and created send_packet() function in send_packet.h/c.
  • Pulled a bunch of variables and defines (NUM_DATA_SETS, NUMBERS_PER_SET, DATATYPE_BYTELENGTH , DATA_ARRAY_LENGTH , ADDITIONAL_NUMS, notRTS, T1_INT_FLAG, x_i, u_i, w_i, x_sum, w_sum, MAX_WHEEL_V_TICKS, deadband, COMMR, SAFEDIST, MINDIST, u_x_ideal, u_y_ideal, x_motion_integral, y_motion_integral, SQUARE) that were scattered across h files into global_vars.h/c. Makes it easy to include them in a particular file with the extern keyword.
• Added color_cal() function in color_cal.h/c
• Added wheelSpeedSingleBot to wheel_speed_coordinator

To Do

• Finish color_cal
• Make the vision system position information updater smarter.
• Replace wheelSpeedSingleBot with the three step move controller from NUtest.c
• Implement new algorithm
