1. General Presentation

The terms "Gripper", "Adaptive Gripper", "Robotiq Gripper", "Robotiq Adaptive Gripper", "B-Model", "2-Finger Gripper" and "2-Finger 200" used in the following manual all refer to the – Robotiq 2-Finger Adaptive Robot

.Gripper 200–

Note

The following manual uses the metric system, unless specified, all dimensions are in

.millimeters

Note

The following section presents the key features of the Gripper and must not be considered as appropriate to Gripper operation, each feature is detailed in appropriate sections of the manual. Safety guidelines must be read and understood before any operation is attempted with the Gripper.

The 2-Finger Adaptive Robot Gripper 200 is an electric robot peripheral that is designed for industrial applications,– featuring high grip force, rugged design and sealed casing. Its design makes it a unique robotic end-of-arm tool to quickly pick, place and handle a large range of parts of varying sizes and shapes.

The Gripper has two articulated fingers that each have two joints (two phalanxes per finger), as shown in Figure 1.1. The Gripper can engage up to six contact points with an object (two on each of the phalanges and on the palm). The fingers are underactuated, meaning they have fewer motors than the total number of joints. This configuration allows the fingers to automatically adapt to the shape of the object they grip and it also simplifies the control of the Gripper.

Details on the power wiring and communication wiring can be found in section and its subsections.3.5 Wiring

The 2-Finger Gripper has a single electric actuator for opening and closing the fingers, the fingers automatically adapt to the shape of the object manipulated. Fingers will adopt either a parallel grip or encompassing grip as shown in figure 1.2.

Robotiq 2-Finger Adaptive Robot Gripper - 200 Instruction Manual

Figure 1.2 : The encompassing and parallel grip.2-Finger Adaptive Robot Gripper 200–

Note

It is important to note that a parallel grip can only be performed when the fingers touch the object with the distal phalanxes first. Inversely, for an encompassing grip, the fingers must touch the object with the proximal or the lower section of the distal phalanxes first. Also, to ensure stability, the object should be held against the Gripper palm before performing an encompassing grip.

Info

Closing or opening is done via "Go to requested position" command and is input to the Gripper.

Whether the fingers close to produce an encompassing or fingertip grip is decided at the

. It will depend on:Gripper level automatically

The part's geometry; The relative position of the part with respect to the Gripper.

In other words, picking the same part could result in either an encompassing or fingertip grip based on a part's position and geometry.

The 2-Finger Adaptive Robot Gripper 200 encompassing mechanism can also be locked allowing– only parallel movement of the fingertips, the Gripper then acts as a classic parallel claw. Locking the parallel movement mechanism only requires a 12 mm axle (see ) to be inserted on each finger in the appropriateSpare Parts hole, see for details and Figure 1.3 for location of locking hole.section 3.3.1

The 2-Finger Adaptive Robot Gripper 200 also offers internal and external gripping. The fingers can pick hollow– parts by applying pressure with the outside of the fingers. See Figure 1.4 for representation and see forsection 4.6 details on the possible position commands for your Gripper.

Note

The Gripper actuator provides the same force with the inside or the outside of the fingers, but beware that surface contact may not be the same.

The Gripper is powered and controlled via the Robotiq Controller (2-Finger Adaptive Robot Gripper 200 Controller,– Figure 1.5). Upon delivery your controller will be set with the adequate communication option and ready to use. The details on the controller wiring and usage are described in and .section 3 section 4

The Robotiq 2-Finger 200 Gripper equilibrium region is the gripping region that separates the encompassing grip– from the parallel grip. When gripping an object close enough to the inside (palm) of the Gripper, the encompassing grip will occur (unless the object size or shape is not adequate) and the fingers will close around the object. If gripped above the equilibrium zone, the same object will be picked up in a parallel grip and the fingers will close with a parallel motion.

The following Figure 1.6 shows the , the , and the encompassing grip region equilibrium zone parallel grip

on the 2-Finger 200 Gripper finger pad :region –

Figure 1.6 : Equilibrium zone for the Gripper finger pad.

Info

The same principles apply for an inside grip, but the encompassing grip region becomes the parallel grip region and vice-versa.

Info

The equilibrium zone will remain the same even with custom made fingers.

Hint

Picking an object directly in the desired region is a good way of predicting the grip mode that will occur, when contact is on the equilibrium zone, small variations in the size of the part and the position of the Gripper will result in different gripping modes.

4. Control

4.1 Generalities

The Robotiq 2-Finger Adaptive Robot Gripper – 200 is operated from the robot controller (see Figure 4.1.1) using an industrial protocol (EtherNet/IP, DeviceNet, CANopen, EtherCAT, etc.). The programming of the Gripper can be done with the of the robot or by offline programming.Teach Pendant

Info

The operator can control the force and the speed of the fingers. The fingers movement is always synchronized, movement is done with a single "Go to requested position" command (the motion of each mechanical phalanx is done automatically).

Since the Robotiq 2-Finger Adaptive Robot Gripper – 200 has its own controller, high-level commands such as "Go to requested position" are used to operate it. The Robotiq Adaptive Gripper 2-Finger – 200 Controller takes care of the regulation of the speed and the force prescribed, while the mechanical design of the fingers automatically adapt to the shape of object(s).

Figure 4.1.1 : Robotiq 2-Finger Adaptive Robot Gripper – 200 connections.

Robotiq 2-Finger Adaptive Robot Gripper - 200 Instruction Manual

4.2 Status overview

The 2-Finger Adaptive Robot Gripper – 200 returns several registers of information to the robot controller:

Global Gripper Status - A global Gripper status is available. This gives information such as if the Gripper is closed or open.

Object Status - There is also an object status that lets you know if there is an object in the Gripper. Fault Status - The fault status gives additional details about the cause of a fault or warnings about the

current controller status. Position Request Echo - The Gripper returns the position requested by the robot to make sure that the new

command has been received correctly.

Motor Position Status - The information of the motor position is also available. Current Status - The current of the motor can also be known. The force applied at the actuation linkage of

the finger can be known from the current, since the torque of the motor is a linear function of the current.

Robotiq 2-Finger Adaptive Robot Gripper - 200 Instruction Manual

4.3 Control overview

The Gripper Controller has an internal memory that is shared with the robot controller. One part of the memory is for the robot output, . The other part of the memory is for the robot input, (seeGripper functionalities Gripper status Figure 4.3.1). Two types of actions can then be done by the robot controller:

Write in the registers to activate ;robot output functionalities Read in the registers to get the of the Gripper.robot input status

Info

The Gripper must be initialized (activation bit) whenever the power is turned on. This procedure takes a few seconds and allows the Gripper to be calibrated against internal mechanical stops.

Caution

The object detection is precise only to the order of a few mm. In some circumstances object detection may not detect an object even if it is successfully gripped. For example, picking up a thin object in a fingertip grip may be successful without object detection occurring. For this reason, use this feature with caution. In such applications the "Fingers are at requested position" status of register is sufficient to proceed to the next step of the routine.gOBJ

4.10.5 Application with Universal Robots

This section contains some additional information related to the communication between the Gripper and the Univer

model and using the protocol. sal Robots UR-5 UR-10 Modbus TCP

Modbus TCP works with 16-bits registers, whereas the Adaptive Gripper is configured using 8-bit bytes. Therefore, it is necessary to compute the value of each 16-bits register using two bytes. Also, the endianness is different for the Gripper than for the robots. This means that the first register is built using the following formula:UR

REGISTER0 = BYTE1 + 256 * BYTE0

Tip

One thing to try first is to send the value 256 to the REGISTER0. This command (1 on the activate bit) will trigger the initialization routine and therefore you should see the Gripper open and close to reach its mechanical stops.

Writing and reading other registers will be based on similar computations. Also, please note that the read/write registers are not the same. As an example, writing to REGISTER0 will send a command to the Gripper whereas reading REGISTER0 will give you the status of the Gripper.

Robotiq 2-Finger Adaptive Robot Gripper - 200 Instruction Manual

Info

The "Actuation Force" is the force that can be applied to an object by the motors of the Gripper. The Gripper is self-locking.

The user of the Gripper must always ensure that the result of the forces being applied to the finger is always lower than the maximum holding Force. As defined in figure 6.2.1, the weight that can be lifted is defined by :

F is the force that is applied to the load by the Gripper. Cf is the coefficient of friction between the fingertip pads and the load.

Sf is a safety factor to be determined by the robot integrator.
