RADIO FREQUENCY REMOTE CONTROLS IN MOBILE MACHINES

摘要

You are an operator of a concrete pump that is delivering concrete to the top of a six-story building. You need to move the nozzle into position and have the ability to start and stop the flow of the concrete into the forms that your crew has built. Screaming "Turn it on" and "Move it a little left" and "Move it a little right" through a bucket brigade of people relaying your responses back to the machine operator is a very inefficient, unsafe way to control the work.
