I was Thinking about getting some more sensors besides the ones that come with the set like the IR LINK, Compass, Accelerometer ECT. Which one do you like the best? So pick which one that you have, want , or would like the most. You can select up to two of them if you cannot make your mind up. Also if there is just one that you love so much You can just vote by replying.

Go over to the forum to vote on your two favorites.

Poll: Which Sensors are the best?

Here are the ones that I thought would be the most popular:

• Hi Technic IR LINK

• Hi Technic Compass Sensor

• Hi Technic Acceleration / Tilt Sensor

• Hi Technic Gyro Sensor

• Hi Technic Color Sensor

• Mindsensors Acceleration Sensor

• Mindsensors PS2 Interface

• Mindsensors Compass Sensor

• Mindsensors Infra Red Obstacle Detector

• Mindsensors RCX to NXT Communication

LEGO has now Unveiled the winners of the NXTLOG building challenge:

MINDSTORMS NXT Camera Bot Building Challenge Winners

I stumbled Across this video on YouTube and thought it was awesome. It uses a unique way of meshing the green wheels to the 40 tooth gears. from what you can see in the video it looks very strong and powerful.

2+1 = 4 . This robot’s function is a special drive train called a Motor Multiplexer. It works by having 2 motors to drive the vehicle, and another motor in between the 2 to slide them forward along a gear rack. When they are in the front position a bump sensor is pressed, and it stops the center motor. The 2 motors are now disengaged from the wheels, and engaged to the 2 worm gear-boxes on the front, which have attachments on them. So, basically, it’s purpose is to have 2 powered drive wheels and 2 powered attachments, with only 3 motors. It was originally designed for FLL.

Here is the video of the robot mezzauk the winner of NXTLOG 5000.

Here’s a great new project I just made: a forklift!

Giganto is a joint effor of several people I know and me. It uses two XL PF motors, several NXT motors, and two NXTs. This is it’s second version, and while it is still not THAT big it’s alot bigger than many robots I have built so far. See more of it on NXTLog Here:

And by the way, the Lego Technic Bulldozer I bought came in the mail today, so some of my upcoming projects are going to have a obvious size difference than my old ones!

Meet the (S)emi (P)ortable (M)usic (P)layer (SPMP)!This is the new hi-tech music player! The iPod now has a rival! Or maybe I should wait till someone buys mine before I say that…Anyways, this is a robot that can carry around your Boom Box wherever you go! It even has a rack to carry all of your CDs. It’ll play mp3s too as soon as LEGO improves the sound capability of the NXT… (hint, hint, LEGO!)And if your music is all on your computer…It will carry that too! More pictures

Here is the Newest NXTLOG building challenge:

From NXTLOG:

“These robots are made for walkin’

Alpha Rex can’t be the only biped you’ll ever make, so we’re asking you to create the NXT two legged walker!

Bipeds are said to be the most difficult robot to make, but we know NXTLOGgers are up for the challenge!

All entries to NXTLOG fall under the Terms of Service

Entries must be submitted from Saturday March 1, 2008 - Monday March 31, 2008

All entries must be tagged “NXT200803″

Only LEGO elements may be used.

There is no limit on the amount of LEGO MINDSTORMS NXT sensors, motors, NXT programmable bricks, HiTechnic sensors, or Bluetooth communication. No home brewed sensors allowed.

A programmable LEGO MINDSTORMS NXT brick must be onboard the robot and must control the robot’s actions.

The NXT robot must be a robot that can take still pictures with a camera and you must explain how the robot is a “Biped” robot in your NXTLOG documentation.”

And the winner of the 5000th NXTLOG entry is: mezzauk and his Creation: Mars Explorer Mk1 with Lander(PF Inc)

His Creation Defiantly deserves #5000 Here is Part of his description go HERE to see more of it.

“This is my first NXT project. It is a simple explorer with a PF enabled Lander. The explorer begins by ordering the lander to lowering both sides then the front so it can exit. I had a medium PF motor spare so quickly stuck a small radar/communication tower at the back - it rotates whilst the left, right and front are deployed.

The explorer has all sensors built in but of course only 4 work depending on which program I choose to use. I am working on 3 programs 1st - will use the light, compass, IR distance sensor and Pf Sensors. 2nd - light, compass, IR and ultrasonic sensors and finally Compass, IR, Ultrasonic and Touch.

My main program uses the light sensor to locate the brightest source using the turntable, record the compass heading and use the heading to navigate to the light source…” More

There were also many others that were very nice as well Go check them out HERE.
