I just had to share this awesome robot that can autonomously fold and shoot paper planes! Very cool.
The next installment of the LEGO Mindstorms platform -EV3 – has recently been announced at International Consumer Electronics Show in Las Vegas. EV3 is to succeed NXT and continue the LEGO robotics product line.
MINDSTORMS EV3 will enhance the on-brick programming, so it should be possible to build and program robots without using a computer. The highly-hackable Linux firmware will allow robots to be controlled from an iOS or Android mobile phone. The new OS is part of a much versitile system, as the EV3 includes as SD card for storage, and a built-in infrared sensor.

LEGO MINDTSORMS EV3 is expected to hit stores mid-2013, the core unit retailing for US$350.

I did promise that I’d release the source code of the Not eXactly C program I used for this year’s RoboCupJunior Rescue, and now I have. The code is available on GitHub: bungeshea/rescue. Enjoy!
Aswin over at Guy NXT Door has posted a rather informative article about the in’s and out’s of the LEGO ultrasonic sensor. Definitely worth a read.

This round was my worst round for the day. The course was composed of quite a few turn tiles without shortcuts, a ramp tile and of course the chemical spill tile complete with a can-victim.
My robot completed the course fine. When it got to the water tower tile the scan missed the can and the robot drove straight off the board. Back to the start, another faultless run through the course but this time at the can challenge tile the robot saw someone’s foot and thought it was a can. Back to the start again, but by then the timer had gone off. Fortunately the scores from this round were dropped at the end because it was my worst round. At the end of this round I was placed 4th.
