November 11, 2010 A Lego Mindstorms robotics kit controlled by an HTC Nexus One smartphone successfully untangled a Rubik’s Cube puzzle in 12.5 seconds at a ARM developer conference in Silicon Valley. Here is a video of it solving a cube. Source: Device Guru

Durante el campeonato de sumo robótico hubo una demostración de destreza futbolística de parte de un humanoide bautizado Forlán! Aquí les dejo un video donde claramente se ve un derroche de talento! jeje

A couple of videos, the first of our robot and the second of another group. Enjoy!!! And here comes the robot of another group, go Junior!!!

Here you can see the scenario. The robot has to take one cube of each color an put them in line on the right side. At the end there should be 12 lines of cubes of different colors on the right side. Here are two robots. At the bottom is one following the black line and sensing distance to detect the presence of cubes. Above is one trying to load some cubes. Each robot has to do the work by itself, but while we try each group tries its robot on different places. A look from above. The robot on the left is sensing the color of the cubes and the robot on the right is following the black line.  This robot took 3 cubes and is taking them to the other side.

PC Pro has performed a comprehensive test of Windows 7 vs Ubuntu 10.04 . They've tested and scored the two operating systems on a number of criteria, including usability, bundled apps, performance, compatibility and business. The final result is much closer than you might expect. 'Ubuntu is clearly an operating system on the rise,' PC Pro concludes. 'If we repeat this feature in a year's time, will it have closed the gap? We wouldn't bet against it' Source:  PCPro - read through slashdot

My first robot build with Lego Mindstorms, created with a group as an assignment of a University subject. As it is our first time it does very little, it just manages to stay in the dohjo by detecting the white line. Also if it detects an object it attempts to load it and carry it to the border to unload it. It uses an ultrasonic sensor to detect this objects. It has a color sensor 1 cm above the ground to detect the white line. It also has contact sensors at the back but we didn't use them, although we planned to. On the video below you can see two runs. The first time I forgot to connect the color sensor, so you can see that the robots bumps out of the dohjo. The second time the color sensor is connected. You can see the light shining on the floor on the left side of the robot. Well, hope you enjoy!
