When I was younger, my grandmother worked for a newspaper and would bring home leftover rolls of paper. Usually, the rolls were several feet wide and had 10-20 feet of paper left on them and they were free. Look up plotter paper suppliers and (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

Hi - I posted a letter just before and I don't know If it went thru. I take it again there - Is there some hardware modifications to Mindstorm so it can have more IO ports - like more Motor control ports and more sensor ports? - And a second thougt (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

| | RE: optical mouse chips as vision sensors?
|

Since the optical mouse is a miniature camera, the same type of principal could be applied using the Lego Camera, maybe even with a custom template in VC. This would at least be an "all lego" solution (for the purists out there). The focal point (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

| | Re: optical mouse chips as vision sensors?

This whole thread just caused an interesting thought to pop into my head, although I suspect it would only apply to cases where LegOS were being used. If the mouse serial port output (transmit line) were to be connected to a LMC555 (running at (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

One other interesting thing about this idea-- If it works, not only will you get the optical sensor, but you can probably get up to 5 touch sensors and a rotation sensor at the same time. I'm not sure how the signal is sent, but will the RCX be able (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

Just use the bottom half of the mouse, trimmed as much as possible, as a skid plate. It will need to be mounted to allow vertical movement, but it should work alright. This wouldn't solve the spin issue, but the clearance shouldn't be a problem. A (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

(...) I knew Assembler would come into play sooner or later. I have downloaded a copy of the H8/300 Assembly language spec. What I still don't understand is how you turn the object code into 'S'-type records with 'ld'? (...) Can I assume the RCX has (...) (23 years ago, 1-Jul-02, to lugnet.robotics.rcx.pbforth)

Another idea would be to get a big piece of dry erase (white board). I got a 4x8 ft piece from Home Depot for about $10. Then, your ant could draw all over the 'floor'. You could put a black 'wall' around the edge, to keep your robot inside. This (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

As I wrote in my last mail I'm planing to build a system for robots guidance and communication similar to ants. I can't get a big enough paper and I can't paint my floor so anyone has an idea of how to 'draw' a path without damaging my floor. The (...) (23 years ago, 1-Jul-02, to lugnet.robotics)
