NXTasy Challenge 2 - “NXT Triathlon”
Friday, December 1st, 2006The NXTasy Challenge #2 is getting started! This time we have a programming only contest, which requires you to build TriBot and use the test pad to complete three tasks. The exact details, rules, prizes etc. will be published in the next few days, but I didn’t want to disappoint our readers waiting for the announcement.
So, here is the overview - write a program (in any language NXT-G, NBC, Robolab, LabView, RobotC etc.) that moves the tribot from the “START” mark on the pad, completing three rounds on the black line (task #1 - line following), turns around and complete three rounds outside the line (task #2 - dead-reckoning) and finally locates, aims and capture a target positioned somewhere in the middle of the pad (task #3 - targeting).
I’ll brief you on the exact details when I finialize them, and get answers from possible sponsors regarding prizes. Till then - start planning!

PSP-Nx NXT-G Block Preview
Friday, December 1st, 2006
How many blocks do you need to turn your NXT into a remote controlled car? three blocks (well, four if you count the loop). Here’s a screenshot of the program that does it. The first block is the PSP-Nx block I’m writing for mindsensors.com, which communicate over I2C with the PSP-Nx PS2 controller interface by mindsensors.com. This new sensor block outputs the four analog joystick values scaled to the range -100 to +100, and can also check the status of the many buttons in the PS2 controller. Of course, it can be used within a Wait block, a Loop block or Case block, just like any other sensor block.
The block is planned to be released next month, when the NXTToolkit for LabView is announced.
