(...) Actually, I've found that the orange button cannot be used independently, at least not from an NXT-G program. A simple program in NXT-G demonstrates the buttons supercede each other as follows: Right button (lowest priority) Left button Off (...) (17 years ago, 21-Jan-08, to lugnet.robotics.nxt, FTX)

(...) Confirmed. The arrows and grey button share a common resistor ladder and only one can be detected. But the orange "on" button has an independant circuitry and can be used separately. See keypad schematics in the HDK. Philo (17 years ago, 21-Jan-08, to lugnet.robotics.nxt, FTX)

Can someone confirm that the front panel buttons on the NXT are wired in such a way that it does not work to press two of them at once? Not too surprising, I suppose, just as early computer keyboards were pre-decoded to signal which single key was (...) (17 years ago, 21-Jan-08, to lugnet.robotics.nxt, FTX)

(...) Nice. And I agree, nice-looking. I once Bricklinked some of those same "rubber skirt" pieces for this, but never did get them in an effecter that I liked (I was trying smaller at the time). Now I use the flexible 1x2 studless beams that first (...) (17 years ago, 19-Jan-08, to lugnet.technic, lugnet.robotics)

Hey everyone. I have built a realistic grasping end effecter that can feel when something in is its grasp (without touch sensors). I have attached a deconstructed version that I use. (URL) principle is pretty simple. As the end effecter closes and (...) (17 years ago, 18-Jan-08, to lugnet.technic, lugnet.robotics)
