  1. Meeting - 2013-09-04
  2. Meeting - 2013-09-11
  3. Meeting - 2013-09-18

(Global) Planning

Week 1 (2013-09-02 - 2013-09-08)

  • Installing Ubuntu 12.04
  • Installing ROS Fuerte
  • Following tutorials on C++ and ROS.
  • Setup SVN

Week 2 (2013-09-09 - 2013-09-15)

  • Discuss about splitting up the team by 2 groups (2,3) or 3 groups (2,2,1) to whom tasks can be appointed to.
  • Create 2D map using the laser scanner.
  • Start working on trying to detect walls with laser scanner.
  • Start working on position control of Jazz (within walls i.e. riding straight ahead, turning i.e. 90 degrees).
  • Start thinking about what kind of strategies we can use/implement to solve the maze (see usefull links).

Week 3 (2013-09-16 - 2013-09-22)

  • Start work on trying to detect openings in walls.
  • Start working on code for corridor competition.
  • Continue thinking about maze solving strategy.

Week 4 (2013-09-23 - 2013-09-29)

  • Decide which maze solving strategy we are going to use/implement.

Week 5 (2013-09-30 - 2013-10-06)

  • To be determined.

Week 6 (2013-10-07 - 2013-10-13)

  • To be determined.

Week 7 (2013-10-14 - 2013-10-20)

  • To be determined.

Week 8 (2013-10-21 - 2013-10-27)

  • To be determined.

localisation code (matlab generated)

clc %%x is driving direction!

Y1_1=-5; X1_1=-2;

Y1_2=-6; X1_2=6;


Y2_1=6; X2_1=-5;

Y2_2=5; X2_2=-6;

rc1=(X1_1-X1_2)/(Y1_1-Y1_2) %%of left-hand line
rc2=(X2_1-X2_2)/(Y2_1-Y2_2) %%of right-hand line

%%##determine relative driving angle
Theta=tan(rc1+rc2)/2

%%##determine distance to left wall
offset1=X1_1-Y1_1*rc1;
Y1=-offset1/rc1

%%##determine distance to right wall
offset2=X2_1-Y2_1*rc2;
Y2=-offset2/rc2
