Last year we had a four-foot-long pivoting arm to hold tubes and an about-face button on our controls. The about-face depended on the gyro, which wasn't plugged in properly. To make a long story short, the robot spun around at high speed flinging the arm out in an 8' diameter circle. That day we learned to slow the about-face down, secure the arm from lifting as well as from falling, and never test driving code in a tiny room.
