(...) I was comparing sensor reading to sensor reading and your point compares sensor reading to motor on/off condition, which is even better. I have never considered your idea of motor stall. That is probably because I am notorious for high gear (...) (17 years ago, 19-Jan-08, to lugnet.technic, lugnet.robotics)

(...) 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)
