Re: Problem with setting robot's position

by Simone Gaiera :: Rate this Message:

sorry for the three post but there was error 500 so i try to post three time...

the problem is even worse...
now with - degree the robot starts in 0 and decrease always the value -0.01 -0.04 -0.06 so with degree -10 we have -degree from the robot so ideally I think is correct.
whith degree it do the same but whe have +0.01 +0.04 +0.07...

the problem is that when start is 0 when it turn 90 degree the value is about 0.8 but in stage the value is dtor(-90) that is -1.57

when the robot return in the initial its value is 1.2 and not dtor(90) and when he turned in 90 degree again its value is 1.8 and so on...
I'm sayng only that is too different from stage...

Are you trying to say that the roomba is reporting a positive turn
displacement when you command a negative turn rate?
