 | | Some questions on batteries and AC power for lego
|
| There seems to be a difference between the voltage outputs of battery boxes and wall powered sources like the train speed regulators. From just listening to the sounds that motors make, a battery box puts out the same voltage as a speed regulator on (...) (18 years ago, 15-Feb-08, to lugnet.technic, lugnet.robotics, FTX)

|
| LOL, the School in Brooklyn where I teach Robotics, gave me an NXT Kit (consumer version) to create a robot for them to use at the Science Fair. [LEGOSet 8527] I did not have a bag to carry the box, so I carried it on the Subway. LOL, everyone was (...) (18 years ago, 14-Feb-08, to lugnet.robotics.nxt, lugnet.general, FTX)

| (...) Strangely enough, the AVR does NOT read motor encoders, the lines coming from the encoder directly enter the ARM processor... Philo (18 years ago, 14-Feb-08, to lugnet.robotics.nxt)

|
| (...) Yep. But note that Philo was talking about *torque*, not force. A torque of 50 N•cm means that it could supply a force of 50 N with a lever arm of 1 cm, or a force of 500 N (more than 100 lbs) for a lever arm of 1 mm... but that would imply an (...)

| Thank you for clarifying this, Brian. I was reading (URL) It stated that the NXT with "Stalled torque) up to 50 N.cm. 50N... it equates approximately 10lbs?! That is without any further gearing down, but just the NXT motors!? Wonder if anyone has (...) (18 years ago, 13-Feb-08, to lugnet.robotics.nxt)
