Roomba wall follow command?

Question

does anybody know the code to make a roomba follow a wall. we are using a Java based program. the code to make the roomba go is roombacomm.drive([speed],[radius]). we are trying to get the roomba to follow a wall, either left or right, to get out of a maze.

some other samples of our code:
if ( roombacomm.bumpLeft()) {
roombacomm.pause(200);
roombacomm.spinRight(90); }
roombacomm.pause([duration]);


thank you for your help.

Answer 1

if bump_left
turn a little right (5 degrees)
go fwd
else
// not bump left
turn a little left to find the wall again.
