PS2 mouse + Arduino = RC car odometer and speedometer(Emaxx)

This video shows how I managed to mechanically connect the motor of the Traxxas Emaxx to an old PS/2 ball-type (mechanical) mouse. The device is connected to an arduino to capture the data.

The mouse encoder is modified so that it only counts two pulses per revolution because I prefer wider range than better precision.

This is a cheap and easy way to build an odometry device for your robotic platform (if the motor does not provide those measures already).

See a tutorial in www.https://webfiles.uci.edu/cagell/Dreambot/photo_gallery/photo_gallery.htm

The sensor is part of the DreamBot project developed by Carlos Agell under the supervision of Professor Kane H. Kim and with the funding of Fundación Caja Madrid.

This project is part of my MS thesis in the DREAM Lab of the EECS department at University of California, Irvine (USA).

The autonomous vehicle will have a buch of other sensors. Some other videos of the Dreambot can be found at http://youtube.com/cagell . For downloads please visit http://www.carlosagell.tk .

How you measure the speed (Velocity) What Software you use and its accurate????

Cause I making a robot RC all terrain car and i had also this on mind but my problem is accuracy and software....pls respond

I get it... good work, but damn man get a better camera! No one will know how "genius" you are if they cannot see it. Don't say you don't care either because you posted this video for all to see...you do.

that a good idea use one of the axels in the mouse and read it with the arduino not bad 5 stars
