Challenge #1 Pull That Weight
NXTCentral’s first challenge is now over!!! We sadly only had 3 entries for the challenge. Here are the rules for challenge #1:

I am challenging all builders to pull as much weight as you possibly can. This will test your creativity to build a robot that not only can pull a bunch of weight, but that looks like something that can actually pull it. Will it be like a tug boat, or a Locomotive? There is no limit on the amount of weight that you can pull. You must pull the weight 10 feet in the lowest amount of time.

The following are the people and their Robots who entered

mini_man176 – The Tractor
NXTMonger – TugBot II
Snowblader13 – Loco the Puller

And the winner of NXTCentral Challenge #1 is:

NXTMonger With his TugBot II, He was able to pull 10.3 Pounds in 1 Minute 21 Seconds!!! Here is a pictures and video of his Bot:

Snowblader13 came in 2nd with 8 pounds pulled in 4 Minutes 15 Seconds. Here is a pictures and video of his Bot:

Mini_Man 176 came in 3rd pulling 3.3 pounds in 5 Minutes 36 Seconds. Here is a pictures of his Bot:

Please let me know if you have any more questions or want o see more photos about the robots.

LEGO.com MINDSTORMS NXTLOG MINDSTORMS NXT NXT Building Challenge

snowblader13 — Fri, 02 May 2008 08:00:50 +0000

NXT NXT…? Are you seeing double? Yes! We are presenting a doubly fun building challenge where you create a robot that uses 2 NXT bricks! We are also giving you double the amount of time to enter this challenge (projects must be entered by June 30, 2008).

The 2 NXT’s can be onboard the robot or the 2 NXT’s can be separate (for example if 1 NXT is used as a remote controller for the 2nd NXT). The NXT’s must communicate with each other.

Don’t have 2 NXT’s? Why not enter the challenge with a friend!

Video: LEGO Bobcat Skid Steer Loader

snowblader13 — Sat, 19 Apr 2008 07:11:57 +0000

Here is a really cool Bobcat that i found on you tube, it uses Lego pneumatics to control the lift and tip of the bucket. This is a really good example of how one can combine pneumatics and the NXT together. I wish there were more information on it so that it would be easier to replicate, or make improvements.

The NeXT Bus

NXTMonger — Thu, 10 Apr 2008 08:01:29 +0000

This is my first entry for the Earth Day Building Challenge: The NeXT Bus! It is one of the first robotic public buses, and possibly the first made out of LEGO.
So here is how it helps the Earth:
This bus uses the same amount of energy as a TriBot, right? Well, maybe a little more, but about the same. So what’s the point? I’ll tell you. This bus easily carries 8 minifigs, but these minifigures are traveling alone, so if they weren’t on this bus, they’d be in 8 different cars! So with this bus, you would be using approximately 1/8 of the energy that would have been used.
Admittedly it doesn’t look much like a real bus, but at least it is functional! It has rack-and-pinion steering like a real bus, windows etc.

NXT Connect 4 Robot

snowblader13 — Wed, 09 Apr 2008 09:00:48 +0000

Here is a pretty cool project that Sascha from Germany Sent me.

Here is the information from Sascha:

“This is the Lego NXT “4 In A Row” robot project.
This robot is able to play against you on itself.
He is independend of any computer, so the program – programmed with NXC – is running on the NXT brick.
The human player can choose the row while pushing the touch sensor as often as the row’s number. The computer decides on its own, which row would be the best for it.
This KI is working mainly on the MINIMAX algorithm. However the computer is not as hard as i want him to be, because of the less NXT Brick speed.
the algorithm works like that: The computer simulates the next 3 possible steps and gives any game situation a specific number of points. The Row with the most points will be the next computers choice.
The robot uses three NXT motors:
- one is moving the gameboard
- the second fixes the stones
- the third opens the gate”

Golden Lego Bricks

Airkraft — Mon, 07 Apr 2008 20:04:45 +0000

As we all know, Lego turns 50 this year and to celebrate they’ve produced a bunch of “gold” bricks as a free gift with purchase of over $50.

The new set, “Town Plan” also includes three 2 by 2 golden bricks as well as a letter from company owner Kjeld Kirk Kristiansen, who appeared on the original town plan box when he was much younger and returns on this one.

They’ve also produced a nice little anniversary site with a historical overview of their products.

You can read more about this on the Lego site

NXTrain – a LEGO Monorail

NXTMonger — Sun, 06 Apr 2008 07:33:24 +0000

This is a LEGO monorail I made that ferries Storm troopers over the ravine between… um … stoolistan and chairville. Hope you like it. The stop motion isn’t that great, but that might be because of my lack of any animation software. Still, I think it’s good! The music is by my friend Ben and his dad Mark.

Video: NXT Playing The Drums

snowblader13 — Thu, 03 Apr 2008 05:19:30 +0000

Check this out!! This is a really good example of a robot playing instruments. From what I see it records what he drums and plays the beat back. How cool!!!
