 | | rtl21 - Can Stacking
|
| Hey folks, I had an idea for a new game, and I want to float it here--see if there's any interest. Previously, I had suggested a "can weighing" game. Whoever ends up with the heaviest can wins. This, in retrospect, isn't that interesting. My new (...) (19 years ago, 2-Mar-06, to lugnet.org.ca.rtltoronto)

I tried a nice little 2 wheeled beast with castors, thinking that I'd save room in the 'bot, but the castors threw the 'bot off so much, especially right after a (...)

That would explain why something that seemed exactly the same would work outside the robot, but not when it's (...) (19 years ago, 2-Mar-06, to lugnet.org.ca.rtltoronto)

| (...) Are you thinking the robot could adjust its direction on the fly? In my limited experience, precision matters when the robot is close to the TO, especially if it can cover a lot of ground in the time it takes for the sensors to come back with (...)

This is the main reason I went with two light sensors--knowing that there'll be moving 'bots and such, I wanted to 'home in' using the best and easiest possible way. using the two ight sensors as a differential, you can steer right towards any (...)

The light readings are going to be pretty variable, and the robot targets and obstacles are all moving, so do you really need that much precision to (...)
