Just before the WI regional I ran across an article in SERVO magazine about a spinning battle bot that needed to get IR commands from its operator. He took a 18" x 1" lexan rod and drilled and tapped a hole thru the center. He then fitted the rod over the IR sensor. IR form the remote would be collected by the rod and the threads acted as prisms to direct the light toward the sensor. He got 360 degree coverage and increased the light capturing area from 1/4 square inch to 18 square inches.

We used this on our bot and doubled the range of our IR board.
