 | | nxt controller specification —Elizabeth Mabrey

| | | 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)

| | | | (...) Yes. The AVR is responsible for a number of things, including PWM and encoder reading on the motor ports (IMS), the reading of the front panel button state, power management, and A/D from the input lines for analog sensors. It is not (...) (17 years ago, 13-Feb-08, to lugnet.robotics.nxt)

| | | | | 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)

| | | | | | (...) 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 (...)

| | | | (...) Strangely enough, the AVR does NOT read motor encoders, the lines coming from the encoder directly enter the ARM processor... Philo (17 years ago, 14-Feb-08, to lugnet.robotics.nxt)
