Hi it is almost the easter weekend. I managed to get hold of a large castor wheel at an amateur radio flea market last weekend. My plan is to mount this castor as a third wheel for the robot lawnmower instead of the 2 balancing castor wheels presently employed on the robot.

My infrared proximity detectors are mounted and are working on the +5 volt power supply used for the 386 computer. The detector is unfortunately prone to ambient light even though the signal is modulated at +- 3 Khz and the same filter on the receiver.

I should have more photos of the latest developments which I will post on my web page as soon as I can get them developed. Note the diagrams for the motor control and infrared units are also on my site now.

Greetings to you all
