(...) If you go to the website of the show, they say that *everything* in the junkyard is seeded. Everything that's there was put there by the show's producers. Not that it really makes the show less enjoyable. Although for some strange reason a (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

(...) Yeah, DGPS would probably be accurate enough, assuming you could get around the no-lock problem. (...) I believe the on-board GPS receiver would still need to fix on the Navstar constellation, regardless of whether or not it was a (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

| | New Outdoor Robot Photos
|
|
I took some new photos of a couple of my robots, and they came out pretty good so I thought I'd share them. The photos were taken outdoors in indirect sunlight, with a Canon Powershot S20 3.34MP mounted on a Velbon tripod. Post-processing consisted (...)

I have a Halogen uplight lighting a room and my solar cell will power a motor, with no load up to a distance of around '6 (3' work height) from the light pole. This will fluctuate according to the reflectance's of the ceiling, walls, etc. Rose (...) (24 years ago, 6-Apr-01, to lugnet.robotics, lugnet.dacta)

Okay, gotta play the devils advocate and take this a step further. ;) Robot (noun). A robot has to have an onboard computer (processor) that is takes input from sensors and decides what to do with its outputs (actuators). It must be able to sense (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

| | calculating sensor resistance (Ohm's Law)
|
|
I've been helping my little sister with her RCX-intensive science project, but we just finished all the calculations and her results seem screwy. Does anyone who understands RCX internals and/or Ohm's Law have some time to look this over and make (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

hi Lauren, you're quiet right, the inside of the RCX (in touch-sensor mode) is ok, and Ohm's law is also. So the problem lies probably in the sensor used. The cheap resistive pressure sensors are totally non-linear, more expensive sensors are full (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

|

O.k., I've never had this happen before, and don't know why it's doing it now. A program as simple as: task main() { SetPower(OUT_A,7); OnFwd(OUT_A); } won't stop running after i hit the "Run" button on the rcx (1.5). Also, the little person in the (...)
