Let Your Android Control Your Robot

Today, LEGO has announce a new Android App for LEGO MINDSTORMS NXT.  If you have an Android based phone, you can use this to manipulate your LEGO robots using Bluetooth.  I have a Motorola Droid, and I have two MINDSTORMS NXT sets, but have never built anything with them.  I really should get around to doing something about that.

Tilted Twister – Mindstorms NXT Robot Solves Rubik’s Cube

I just came across Tilted Twister while reading Mike Walsh’s LEGO Blog (link removed, as apparently his site has been compromised). It’s a Mindstorms NXT robot that can solve the Rubik’s Cube!

The really amazing part is that it’s built using only the parts in the stock NXT kit.  Instructions are provided – I’m tempted to make one myself.  (Note however that you either need to buy a special color sensor, or modify the colors of your Rubik’s Cube so that white and yellow can be distinguished by the stock light sensor.

Daniel Rojas’ Cable Car

One of the more impressive LEGO robots I’ve seen lately is Daniel Rojas’s Cable Car. He came to one of the BayLUG meetings recently and met some of us, and told us about the project, and when he finally posted his finished product he was kind enough to email us about it.

It’s a great model of a cable car, and a very clever robot too. Like the real deal, it has a grab-arm which goes below the track to hold on to a cable which pulls it. And it’s controlled by an RCX (Mindstorms). It even has a working emergency brake! Daniel even made a great YouTube video so we can see it in action:
