Re: Turning Accuracy
I would suggest you try with the move block, the same thing you did with the motor blocks. After the move block, put a delay for some time (like 1 second). Make sure the block is set to "Brake". You should see that after motor B & C reach the desired location, the momentum of the robot...

Re: Screen flickered then died.
There was a revision that moved the contents of the daughter board to the main board. Also, the buttons which were about 1/2 inch tall, were extended to two or three times as big, so they could reach to the main board. I don't know the exact dimensions of the buttons, so don't worry about correcting...

Re: Efficiently running RC motor with NXT
My thoughts on this. Are you using the NXT for anything beyond turning off the power when the required pressure is reached? Here's a very nice trick for controlling the compressor pressure... Instead of the pressure sensor, put another [small] piston with a rubber band, to keep it compressed, and on...

Re: Labview problem: IR Link with Power function
A couple comments... 1) Make sure the NXT port is NOT 0-based. The easy way to do that is to use your same program, and plug the IRLink into port 2. 2) The sequence beam is only required if you want to execute several block in sequence. Not really needed here. 3) Is the stop set to true? (does the p...

Re: LEGO is not moving straight!!
The firmware has functions to make the motors move the same distance using PID functions. The call you're making, only sets the motor power, without trying to trying to synchronize them.
You should look to see if there are any parameters, or other functions that include synchronizing them.

Re: LEGO MINDSTORMS EV3 Announced
MCP ? what's MCP ? most people who get invited are very active the in the community. They contribute through the software they make, the models they create or the blogs they maintain. That's all I'm already doing, but got no invitation though. Now I find that very strange. The MCP is "MINDSTOR...

Re: NXT Help

Re: Self balancing motor bike
The hardware is ready, but I lack a lot on the adequate mathematical rules for finding the balancing équations and sensor filters to apply to get my bike standing up (drive and steer). A few programs I saw were far too complex to understand for me and to implement correctly (MatLab, LabView,SimuLi...

Re: RCX Robolab timer issue
I have not seen or heard much about Robolab in several years. I would suggest you look at this web site to try to talk with someone who may know more: http://ceeo.tufts.edu/

Re: vision command
I don't think it's been discussed, here. If it has, not very much. I'm not sure you'll find many pre-made options. The vision command is pretty much just a web cam that plugs into a PC. The PC runs software designed to take input from the web cam, and send messages to the RCX. I suspect it would be ...
