Mechanical Design of Stäubli Gripper

Mechanically operate using a pneumatic cylinder

Pick up tennis ball tube

Pick up tennis ball Withstand a 10.5 lbf

generated from the 60psi

Scara Gripper

Page 12: Assembly Line Simulation With Multi-Robot Control

Scara Gripper• Vaccum Pump that is

connected from the solenoid control valve to the gripper tool suction cup.

• (2) Rollers on each side of the suction cup.

• The suction cup has enough compression when the lid is being placed on the tube that the rollers can put pressure against the top of the lid. The gripper rotates 180° clockwise and counterclockwise to seal the lid.

Design of Lid Nest

Capable of securing 3 lids

Allow access to SCARA vacuum gripper

Be removable

Robot Control Programming

Robots control consists of Staubli Adept controller, Scara Adept controller, and the host computer.

Page 17: Assembly Line Simulation With Multi-Robot Control

Adept Programming

.PROGRAM placelid1()

TOOL TRANS(0,0,100,0,0,0)

CALL tennisballhome()

BREAK

SET a = TRANS(370,-151,56,0,180,0)

BREAK

APPRO a, 50

BREAK

CALL close()

• Both the Stäubli and Scara use V+ programming to control the movements of the robots.

RCML Programming Robot Control Markup Language

Created language that uses XML programs to control the robots in the workspace from a host computer.

A <step> command is used to send instruction to the respective serial port.

Page 19: Assembly Line Simulation With Multi-Robot Control

Sample RCML Code<configuration>

<conn variable= "staubli" connection= "COM2" interpreter="api.AdeptInterpreter"/>

<conn variable= "scara" connection= "COM4" interpreter="api.AdeptInterpreter"/>

<conn variable= "microbot" connection= "COM5" interpreter="api.MicrobotInterpreter"/></configuration>

<execution timeout= "30000">

<for count= "infinity">

<set><step>scara.wait1</step><step>scara.wait2</step><sequence><step>staubli.tubetotrack</step><step>staubli.pickrotary</step>

Java Programming• Java is used as the host PC programming

language.• Existing code interprets the command set

by the RCML program and distributes a string to the serial port by use of the AdeptInterpreter and MicrobotInterpreter.

Java Programming The XX1 microbot was initialized in the

MicrobotInterpreter to control the rotary table:

XX1(speed, m1, m2, m3, m4, m5, m6, t1, t2, out)

Page 22: Assembly Line Simulation With Multi-Robot Control

Work That Can Be Done Java Program For I/O Control Sensor for Microbot rotary table Increase Efficiency

Simultaneous movements of the robots Add more pallets Design of way to load rotary table or system

to supply continuous operation
