Using the Feeder

Gravity Feeder

In this activity, you will create a program that makes the robot pick up parts from a feeder and drop them 

into a metallic can. When the feeder becomes empty, the robot will remain at the home position until parts 

are placed in the feeder.

Writing the Program

On the work surface, place the objects as shown below:

1. 

Gravity Feeder Set-Up

Connect the normally-open contact (yellow and black jacks) of the feeder microswitch to the TTL 

2. 

input 1 of the robot base. The microswitch will prevent the robot from trying to grasp a part when the 

feeder becomes empty. 
Open the 

3. 

RoboCIM

 software. From the Welcome screen, select Create a new

 RoboCIM 

workspace.
