Nils Völker - Robotics - Dotje - Programming and Construction. There are two NXT bricks on this robot, one for the movement and one controlling the pen. Both communicate via bluetooth and are powered by rechargeable batteries, permanently plugged to battery chargers from the ceiling. Three motors on the edges turn the spools and move the robot along the ropes. A fourth motor, connected with the second NXT, rotates a lever that pushes down the pen. The pen is mounted within in an acrylic tube, hanging on rubber bands. I know a lot of people limit themselves strictly to use only Lego parts. The whole construction is about five by six meters large. The process is started as soon a visitor is looking long enough at an image of an object that is inside a viewing box. Then this data is saved into a txt-file and sent to the robot via a very long USB-cable.
The program on the robot, written in NXC, starts reading the txt-file. After it has reached the given coordinate NXT #1 tells the second one via bluetooth to push the pen down on the paper. Nils Völker - Robotics - Spherical Robot. This is a ball-shaped "robot" based on a Lego Mindstorms NXT. It moves in any direction by simply rotating the internal mass horizontally and vertically. At the moment it's remote controlled via Bluetooth from a second NXT. So to be precise it's actually not a real robot more kind of a Rolling-Orbital-Bluetooth-Operated-Thing (to make it short: robot). But seriously: It's planned to implement the ability of moving autonomously later on.
And to answer the most obvious question right away: No, there is no deeper sense or purpose, but a lot of fun driving it. Projects for NXT 2.0. Products.

Thomas Avery has also performed measures on 5292 motors, see Lugnet thread. The roster Weight Supposed to be equivalent to 71427, 43362 motor is 30% lighter.
This is generally an advantage, except when the motor is used as a counterweight, or to balance the structure, for example in COG-shifting walkers. No-load characteristics Test conditions: motor is powered by a variable, regulated power supply. 43362 has a higher no-load current than 71427, probably caused by higher internal friction. 47154 has a fairly high no-load current, because of its 5-stages gear reduction.
As is usual for DC motors, rotation speed is proportional to voltage applied to them, this can be seen on graphs below. Stalled characteristics Stalled current consumption is simply measured with motor axle shaft locked by hand. Take care to avoid extended period stall condition, as power dissipated in motor case is quite high (6 Watts for 2838, 3 W for 71427) will cause a rapid temperature rise. Mindstorms add-ons.
