Welding Robot Programming Controls & Sensors
Welding Flowchart Program
Open the ROBO Pro software. Follow the directions below to complete the activity.
In this activity, you will create your own control program to run the Welding Robot model you constructed
in the last lesson. You will first learn more about the pulse counter and its properties.
Many fischertechnik model robots use pulse wheels. These gear wheels operate a switch four times
for every revolution. With pulse wheels, you can turn a motor on for a precisely defined number of
revolutions rather than for a given time. To do this, you need to count the number of pulses at an input of
the Interface. For this purpose, you would use the
Pulse counter
element, which waits for a user-definable
number of pulses.
Connect your model to the interface and turn the power on.
