LoTek > Challenge > Single set power pulling

Current Scores!

Information

This is a challenge to pull as much weight as possible with the pieces from one set. It's been inspired by Steve Lane's similar competition but simplified (?) a lot since only one set is allowed.

This will prove some really popular sets pretty useless such as the 8480 Space Shuttle due to bad tires while set's like 8720 Power pack will prove quite a challenge indeed! The RIS kit should pull most since it has two motors.

Classes

There will be a class for each motorized LEGO set. There will be a league for each of the classes.

Rules

Sets & pieces

Any set that has an inventory at Peeron is allowed. If it's not there, well, make one and get it up there :) Also, the inventories at Peeron are the official one in this challenge. If the piece you want to use is not listed in the inventory for the set at Peeron the piece is not allowed. Same thing with number of pieces and part color. The color rule is there to at least give us some chance to verify that this rule is not broken.

No modifications to parts are allowed and the entry must be built from 100% LEGO!

Since no lubricants come with the set they are not allowed! Not even water .)

Note that the string, pulley and weight does not have to be included in the set.

Motors

The motor can be made in three ways: Pneumatics, rubberbands and electrical motors.

Pneumatics: There must be an prepumped airtank, the airtank must be filled with an LEGO airpump. No industrial strength compressors or similar! If you use the Airtech clawrig you can build an compressor for your entry since you have the pieces for it. Handpumping while pulling is not allowed. The set must move w/o interaction from outside forces such as pumping.

Rubberband: The rubberbands must be the same kind and number (or less) that came with the set.

Electrical: Batteries in the set's battery box is the only allowed power source. You might use external power while building and testing but when doing a real pull it must be batteries.

After the entry is started it can not be moved or touched by any outside force until it fails or succeeds. The point is to make the LEGO do the work.

Surface and distance

The model must be able to pull the weight for at least 10 cm (3.937 inches). The surface for the puller must be smooth, horizontal and ordinary copy paper should be used as surface.

Weight/load

The weight should be connected to the model via a string and hung over the edge of a table/whatever via a pulley. The pulley must not be arranged in a way that decreases the load on the entry. A picture of the pulley/string configuration is appreciated.

The string between the pulley and the entry must be horizontal.

A hint on the load: Use a small plastic bag and fill it gradually with water, one ml (1/1000 of a liter) equals one gram. The league will be presented in steps of 10 grams.

Looks

The entry does not have too look like something real although it is a bonus :)

How to participate

Take some pictures, write a brief description and post it all OnLine, if you don't have a homepage use Kevin Lochs Brickshelf. Then e-mail a link to the page and it's in the competition and will be placed in it's proper league. Remember to type which class you enters (e.g. what set you used for pieces). Also write how big load you were able to pull :)
