  skos:definition """The Spatial Coordinate Apparatus (SCA) consists of four arms
connected to potentiometers. The top three arms can move in a
vertical plane while the fourth arm can rotate upon its
longitudinal axis. As the arms rotate, the angles of the
rotation are measured in terms of voltages from the
potentiometers and recorded in a computer. These voltage
readings were then converted into 3-dimensional coordinates (x,
y, z) of the endpoint of the top arm.
