To begin the lab, set up the robot controller and verify the functionality of the suction cup by
writing a simple program to turn it on and off using the DO command. Observe the I/O status to
determine which output controls the suction cup. Next, attach the suction cup to a scale, gently
lower the scale until detachment occurs, and record the maximum suction force. Use this data to
calculate air suction pressure. Once the suction cup operation is finished, program the robot to
move in a square pattern using the MOVA command, ensuring it runs continuously until
manually stopped.
For pick-and-place operations, write a program that picks an object at PT1 and places it at PT2
using the suction cup, incorporating DO, TIMR, and JMP commands to automate the process in
a loop. Test suction stability by picking up objects of different weights (50 g to 500 g) at varying
robot speeds (1% to 100%), recording the fastest speed at which the suction cup maintains grip.
Analyze the effect of speed on suction performance by plotting a graph of speed percentage
versus weight. Finally, present a free-body diagram of the suction mechanism and discuss how
weight influences suction stability, drawing conclusions based on experimental data.
