The previous method was more expensive, used large amounts of chemicals and produced much chemical waste. The new robot is housed in a special room and has its own water treatment facility in the next room. All water used in the process is reclaimed and used again. The operators must thoroughly understand the x,y,z coordinate system to program the robot correctly. The robot arm simulates the way a human arm would move, and each joint must be understood in terms of its own x,y,z coordinate system.
Programming is critical and a programming error can result in a part damaged beyond repair.
A ringstand with dowels clamped to represent x,y,z is a simple method of doing this. Students can position the robot arm, then directly measure off the distances using the ringstand guide. Establish a reference point to use as an origin. Graph the series of points on graph paper that will indicate a 3-D plane. To keep things simple, use only positive values.
