Hello, LUGNET readers. In case you don't know, I'm the lugnet.robotics.nxt curator. I used to update the NXT section sidebar with [in]frequent regularity, but during the last couple months I've not done anything to it. I get busy and/or don't take (...)

(...) I am in the middle of creating new API functions for NBC/NXC which will enable the same PF motor control via the mindsenors NRLink device. They should be done and in an official beta (b35) by the end of the week. John Hansen (17 years ago, 20-Feb-08, to lugnet.robotics.nxt)

|

hello, I've read the news on nxtasy.org that the new test release of bricxCC can control the speed of PF motors via the Hitechnic IrLink.. is it possible to do the same thing with the mindsensors irlink ? thank you Cristian (17 years ago, 20-Feb-08, to lugnet.robotics.nxt)

| | NXT on the Subway
|

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 (...) (17 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 (17 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 (...) (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)

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)
