Introduction: Vacuum Gripper System Using OpenCR

About: ROBOTIS is a Global Service Robot Solutions Provider and a leading developer of smart servos (DYNAMIXEL), industrial actuators, manipulators, open-source humanoid platforms and educational robot kits/tech toys…

We provide a way to set the vacuum gripper system using OpenCR. It can be used for the OpenManipulator gripper Instead of standard gripper. It is also useful for using to the manipulators that don't have sirial linkage structure such as OpenManipulator friends.

Step 1: Insert ARDUINO 4 RELAYS SHIELD Into OpenCR.


Step 2: Insert the Coupling Into the Control Valve.

Insert the coupling into the control valve.

One of them uses 6Ø coupling and the other uses 8Ø coupling.

Step 3: Connect the Cable to the Control Valve.

Connect the cable(NEBV-Z4WA2L-P-E-2.5-N-LE2-S1) to the control valve.

Step 4: Insert the Air Tube

Insert the air tube (8Ø) into the pump motor on one side.

Step 5: Connect the Air Tube

Connect the other end of the air tube (8Ø) inserted in step 4 to the 8Ø coupling of the control valve.

Step 6: Connect Air Tube (6Ø)

Connect air tube (6Ø) to Suction cup.

Step 7: Connect the Air Tube (6Ø)

Step 8: Connect the Power Supply, Suction System, and Arduino Shield

Connect the power supply, suction system, and arduino shield as shown below. Here, the cables connected to the control valve can be connected in any way, without distinction between vcc and gnd.
