Hello,
I'm having this issue with the coordinate system on the whiteboard. After setting an initial position by measuring the strings of left and right. The calculated x and y where within a few millimeters off the actual distance. But, when I connect to hardware and start I move the robot upwards towards the top of the board (+motor speed). I then re-calculated the x and y, and the new x and y are incorrect. The initial x and y was about .2171x.2551m respectively. But, the new x,y came out to be .2045x.2621m. I should be about 0.220x0.110m(x,y).
How come the measurement are wrong? I checked the code in task 2 and everything is correct. Could someone further explain to me the coordinate system that is used in this project? I think I understand but there might be something I am missing.
Thanks,
