Entry: chMney
		By GeoBrick

Part Specs:

	RIS 2.0, Ultimate Builder's Set, [a lot of liftarms from] Vision 	Command, and various other less notable sets

Robot Description:

	More or less M shaped (as discussed on the the forum), 		hence the name chMney. The long arm out in front of the 			robot is for a counterweight that keeps the robot from rotating 	backwards as it climbs. The conglomeration of gears in the 	back is a differential system allowing one motor to pull a pin 	to extend the arms and to drop cargo (a rocket-shaped 	doohicky I made just for fun). The arms, once released, are 		extended by several rubber bands pulling the peaks of the M 	together.

Performance Specs:

	Minimum Dimensions: 6.75 in. tall, 11.25 in. wide, 15 in. long
	Maximum Dimensions: 7.75 in. tall, 14.5 in. wide
	Chimney Width: 13.5 in. wide
	Speed: The robot climbed 1 ft. in exactly 25 sec.
	Weight: About 2 lbs.
	Max. Payload: About 3 lbs. (So basically, the robot can 				transport a maximum of 5 lbs. including its own 		weight.)

Program:

	It's a very simple, self explanitory program. The only notable 		thing is the countoff at the beginning. That just gives me a 		chance to get my hands out of the way after pressing the run 	button.

Notes:

	The robot drops its cargo when the light sensor detects 			darkness. In tests, I had a third wall in the chimney. On that 	wall, I drew a black line. So, when the robot reached the line, 	it would drop its cargo and end the program.
