Here is the english transalation

Version 3 validated
November 4, 2009
Version 3 has abandoned the compass to return to the odometer. Early results with the odometer were not conclusive because the software missed pulses. The main loop was too slow and odometer sensors do not cause interruption. So the timer interrupt sensor which scans the odometer. Just turn and reverse are controlled by odometer.

abandonment of the edge detection frequency with the LM567 (PB frequency stability and sensitivity adjustment) to return an amplitude detection signal with a better treatment



The Poulette Version 2
March 28, 2009
Spring has arrived and I am not yet quite ready. But I dropped the chick version 2 today on a lawn, trembling with impatience and ready for battle. The fight lasted 2:10 ET first results are satisfactory but there is still work. Products Some photos below: The control board is equipped with a PIC 16F737 the motor is ensured by 2 geared motors
with 2-blade cutting



voila dropped on the lawn equipped with its bumper, its detectors U.S., its detectors buried wire. The mechanical version 2 is better, electronic pest problems ask me ... (edge detection) to follow so

Hello everyone!
October 4, 2008
The chick is the first version of my robot lawnmower.



Welcome to my blog as my minimalist robot pullet.

I just put up this blog to share my experience and benefit from your comments.

The prototype works but requires reliability and improvement.

I am customer of all good ideas.

I am hmnrobot (french) and would be glad to answer any question.

spring is back and the grass is growing ! the Version 4 is working : the main difference is that the "forward direction", now the blades are ahead, main wheels are at the back more and more Husqvarna like !

So I gather French people dislike cutting the grass as much as Americans?

Actually I enjoy pushing the lawn mower around, but it sure would be cool to have a robotic one just to see the looks on my neighbors faces.

Post a video of ver.4!

You're right , French can be lazy as well but in fact it took me much more time to build that mowbot than cutting the grass with my mower !
Here the video of version 4
