(...) 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 (...) (17 years ago, 13-Feb-08, to lugnet.robotics.nxt)

(...) Many thanks John and Jason for your work on this. I am a comparative newbie to NXC programming but I have my NXT working like a PF IR remote handset now that I set up the sensor correctly! NXC has given me the programming environment to (...) (17 years ago, 5-Feb-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics)

Hi, I wonder if anyone may be familiar with the spec about the nxt brick: I found this on the ww.hobbyengineering.com . NXT Brick * 32-bit ARM7 microcontroller * 256 Kbytes FLASH, 64 Kbytes RAM * 8-bit AVR microcontroller * 4 Kbytes FLASH, 512 Byte (...) (17 years ago, 13-Feb-08, to lugnet.robotics.nxt)

(...) It looks like the PF IR receiver will be very useful for train control and other continuous duty applications. But the only remote available is for intermittent operation. So the only LEGO option to running in PWM/continuous duty is to use a (...) (17 years ago, 31-Jan-08, to lugnet.technic, lugnet.trains, lugnet.robotics)
