Pendant control housing

A machine and control are provided for effecting motion of a function element, such as an adhesive material dispensing gun, and controlling the operation of the function element by means of a control signal proportional to the velocity of a workpoint associated with the function element. The control produces a velocity signal representing the velocity of the workpoint, calculates the value of a control signal using the velocity signal and predetermined constant defining the constant of proportionality and zero velocity output and applies the control signal to a digital-to-analogue converter to produce an output signal for controlling the function element.

Velocity proportional dac for use with a program controlled manipulator

Apparatus and method are disclosed for teaching a cycle of operation to a computer operated robot arm. A keyboard is provided comprising first keystroke means which are operative in two different teaching modes. In a first teaching mode, the keystroke means cause storage of individual instructions defining an operation to be performed by the robot arm at a point in space. In the second teaching mode the first keystroke means are operative for creating a macro comprising a sequence of such instructions for later use. There is a pendant which controls the movement of the end of the robot arm and has second keystroke means for causing a previously stored macro to be assembled into an operating control program for the robot arm. The second keystroke means also may be used for causing assembly of individual instructions into the operating control program.
