Still struggling to get an idea for a robot to compete in the MINDSTORMS Summer Olympics Building Challenge? Here’s a video of an NXT “Gymnastic Robot” that could inspire you. This robot can really move!

The following video was posted in February of 2008 and shows an NXT robot that can always solve the Rubik’s cube—within a minute or less! The robot’s creator is Daniele Benedettelli, who has experimented with a number of robot designs to solve the Rubik’s cube in the fastest possible way.
Movie Monday time! Stepping back to early 2007, here is a video from Brian Davis titled “LNE: LEGO Packbot.” Nothing can seem to stop this robot; one of my favorite parts is the scene with the robot “swimming” across packing peanuts. You can watch the movie below, and Brian has posted a number of pictures of the robot on Brickshelf.
Previously, there was a “secret” NXT movie that could be accessed on the home page of the MINDSTORMS website by clicking an exclamation mark in a sentence. The hyper-linked exclamation mark seems to be gone now, and while the URL is still valid, the same movie and a few others featuring Alpha-Rex have appeared on the “movies” section of the MINDSTORMS website. Check these little movies out if you want to see an Alpha-Rex play ball, dance, and fight a fly (and win!).
I’ve mentioned a particularly funny NXT movie to more than one person over the past couple of months. While this movie has been around for a little while, it’s worth bringing up again. So here’s the link:
The official MINDSTORMS website has upgraded NXTLOG to version 2.0. You can read the announcement here. One of the main improvements is that users can now upload video of their robots. Previously, there was no way to include video, and I’m glad to see that this has been resolved. Check out the new NXTLOG here and start uploading some of your creations!
The official MINDSTORMS NXT Biped Building challenge, which was launched earlier this month, is asking NXT fans to create two-legged walkers—among the most difficult robots to build. Fortunately, the MINDSTORMS website lists some sample bipeds on NXTLOG to give inspiration to the community.
However, a simple video can be very effective when it comes to giving inspiration. Following is a video made by YouTube user Laurens200: it demonstrates one of his NXT biped creations. This robot implements one of several possible methods for creating an NXT biped–and it’s quite amusing to watch!
I’ve added video of Claw-Bot, the robot from Chapter 13 of The Unofficial LEGO MINDSTORMS NXT Inventor’s Guide, to the “Pages” section of the blog. You can also watch the video below.
Claw-Bot is based on the Zippy-Bot model from Chapter 11, adding a claw-like subassembly with an ultrasonic sensor and a light sensor. Claw-Bot moves toward the center of the NXT test pad, spins in a circle until it detects an object with its ultrasonic sensor, and then drives forward to push the object until its light sensor detects the black line. The robot is programmed to find three objects, but it’s easy to change the number to more (or less) than three. Go Claw-Bot!
I’ve added video of Bumper-Bot, the robot from Chapter 12 of The Unofficial LEGO MINDSTORMS NXT Inventor’s Guide, to the “Pages” section of the blog. You can also watch the video below.
Bumper-Bot is based on the Zippy-Bot model from Chapter 11, adding a bumper built around a single NXT touch sensor. Bumper-Bot is content to explore its surroundings by randomly running into objects and then changing its path. Fortunately, robots don’t get headaches from bumping into objects—unless they’re programmed to get headaches, of course.
I’ve added video of Golf-Bot, the robot from Chapter 16 of The Unofficial LEGO MINDSTORMS NXT Inventor’s Guide, to the “Pages” section of the blog. You can also watch the video below. Have you ever seen a LEGO robot golf? This bot scans its surroundings for a special LEGO target, places a ball on the ground (a LEGO ball, of course), and then hits the ball into the target. Despite its size and complexity, Golf-Bot can be created from the pieces in a single NXT set. There’s just not that many pieces left over by the time you’re finished building!
