 | | proximity detection with laser?
|
|
The following idea just came into my mind. Will it work? Put a video camera and a laser projector on the mobile robot. The laser projector beams out a pattern of light. The camera picks up the pattern, then we deduce the robot's proximity by (...) (25 years ago, 4-Jan-01, to lugnet.robotics)

Hey! Competition time! I'm fairly new to the online LEGO community and regular competitions like this sound like a great idea. Glad you have the time to put into it. Cheers, Raoul (ICQ 17521252) (25 years ago, 4-Jan-01, to lugnet.robotics)

GPS requires a clear, unobstructed view of the satellites in the sky. Forget about using it indoors. Earthquake researches use sensors that can detect movements of less than an inch. I don't know how they work, but it involves GPS to some extent. (...) (25 years ago, 4-Jan-01, to lugnet.robotics)

The reason you are getting better resolution is the US Government turned off selective availability (the random noise inserted into the timebase, then encrypted so military applications can use it).

Hi Bob, I am glad you agree, these contests have certainly caused me to stretch my building wings. Scoring is based on the distance to your target, the further your robot can throw, the greater your score. Alternatively, you could go for a target (...) (25 years ago, 4-Jan-01, to lugnet.robotics)

Rich, I think contests are a great motivator for building. I am thinking about entering, and I have a question. The rules say "Place the target at a pre-determined location relative to your robot". Can this be any distance? How is the distance (...) (25 years ago, 4-Jan-01, to lugnet.robotics)

(...) According to their FAQ they can't accept orders for shipment outside of Canada. This is also supported by the fact that you have to enter a Canadian provence to proceed to step 2 of the checkout process. Bummer. Know any Canadians? Dave (25 years ago, 4-Jan-01, to lugnet.robotics)

Well, the print ad I'm looking at has the RDS priced at $267.99 (after $30 rebate) CDN. I assumed they swapped the prices on the two sets, since the RDS is at the lower end of the spectrum. I didn't check the pricing of the RDS online though. -- (...) (25 years ago, 4-Jan-01, to lugnet.robotics)
