WHile i was plugging in the cable for the IR tower, i heard a snap and noticed that some pins on the plug got shoved halfway into the computer. How should i fix this. Also If i were to get a USB adapter for the plug, and plugged it into the (...) (24 years ago, 14-Feb-01, to lugnet.robotics)

(...) The possibilities are endless. I would start with the sensor and move on from there. The stability and accuracy (precision) requirements will depend heavily on the robot configuration. It does not need to have pointed feet like a ballerina (...) (24 years ago, 14-Feb-01, to lugnet.robotics)

(...) The two gates he presents seem a little complex and bulky. I think the reason is the choice of representation for the logic levels 0 and 1...and perhaps even the idea of base-2 arithmetic at all. It seems to me that if you chose '0' to be (...) (24 years ago, 14-Feb-01, to lugnet.robotics)

(...) Well, I think your software has to be able to predict (mathematically) what will happen to the robot and the pendulum as it accellerates the motor. You can't rely on the simple "if pendulum in middle all is well" thing. You need to know the (...) (24 years ago, 14-Feb-01, to lugnet.robotics)

Heh...I left out the key word...That being what's the "MAXIMUM" voltage and/or mA it'll take. I want those 'lil motors running with max torque/output -but I'd rather not fry my RCX's 'lil brain. And even #24 guage is just a wee bit too big for (...) (24 years ago, 14-Feb-01, to lugnet.robotics)

I don't know much about mechanics or walkers, but what about a gyro device that's more stable than a rotational sensor. Surely someone out there would know how to use one of these to "balance" a walker. Of course this means powering the gyro to spin (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

The large weight waiting to drop would be a bunch of (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

(...) I don't have the time to work on this, but I see a relatively simple way to do this that might work well. Build a column to stack all 3 cans into. Place 3 "spikes" roughly dead center at each can, the RCX powers a bar that moves the spikes in (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

Hi There, Hmm, you found the loophole! Okay, the rules have been changed to indicate that all cans must be crushed at least 50%. This should prevent the instant win, but still keep the formula as it was. The updated formula is a good one, but since (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

Sorry if this one has been suggested: (URL) have seen two others, but searches came up empty and didn't someone post a brick sorter that read in a sequence of 1x2 tiles to produce an "order" to be "picked" from hoppers of different colour? Couldn't (...) (24 years ago, 13-Feb-01, to lugnet.robotics, lugnet.general)
