2 Introduction

The RG2 is an industrial robot Gripper, designed for grabbing objects, typically used in pick and place
applications. Its long stroke allows it to handle a variety of object sizes and the option to adjust the gripping
force allows the Gripper to handle both delicate and heavy objects.
The standard fingers can be used with many different objects, but it is also possible to fit custom fingers.
The installation complexity is minimal, the RG2 cable attaches directly onto any supported robot. All
configuration of the Gripper is controlled in the robot software.

7.2.2.2

TCP settings

The option to make the URCap plugin set the TCP [X,Y,Z,RX,RY,RZ] rotation vectors at program start and/or
every time the RG2 performs an action, is available at the top right corner.
If the TCP is controlled manually and the “Depth Compensation” is not used, it is recommended to disable
both check marks. If the TCP is changed dynamically (during a program) and the “Depth Compensation” is
used, it is recommended to enable “set TCP at RG2 action”.
7.2.2.3

Disable single step

If “Disable single step” is selected, the robot program can be started fast and is not dependent on the
number of RG2 nodes, but in this case it is not possible to single step the RG2 nodes. If it is deselected, the
case is the opposite. This option is also located in the top right corner.
7.2.2.4

Depth compensation settings

All the “Depth compensation” settings are used for controlling how the Depth compensation should
behave, when a RG2 node is set to enable Depth compensation.
“Soft stop” will reduce all robot joint accelerations at the end of the compensation and minimize the
integrated compensation error, but will make a small increase of the node execution time.
If the “Lag warning” is enabled the robot will give a warning if the robot movement lags the RG2 above the
specified threshold. The reason for lag can be a low value of the speed slider, low gain, high lookahead time,
strict safety settings, robot kinematic, fast RG2 movements (high force) and full RG2 stroke.
The “Lag threshold” is the threshold that will trigger a warning message if the lag warning is enabled.
The “Gain” is the gain used for the servoj function used in the depth compensation. See the UR script
manual.
The “Lookahead time” is the lookahead time used for the servoj function used in the depth compensation.
See the UR script manual.

Width and Force

“Width” is the target width that the RG2 will try to reach. If the specified force is achieved, the RG2 will stop
at a width that differs from the target width.
“Force” is the target force that the RG2 will try to achieve. If the target width is reached before the target
force, the RG2 will stop moving and the target force may not be achieved at the anticipated width.

7.3.2

Payload

When the “Set Payload” calculation is selected, the object weight must be entered in the Payload field. The
URCap plugin will then perform the calculation of the resulting payload mass (sum of bracket, RG2(s) and
object). The center of mass for the object is assumed to be in the TCP. The object for the active Gripper is only
taken into the calculations if an object is grabbed.
The math behind the calculations:

𝑛

𝑀 = ∑ 𝑚𝑖
𝑖=1
𝑛

1
𝑹 = ∑ 𝑚𝑖 𝒓𝑖
𝑀
𝑖=1

n: number of present components
i: bracket, RG2_master, RG2_slave, master_object, slave_object
m: mass for each component
r: center of mass vector for each component
M: resulting mass send to UR controller (payload)
R: resulting center of mass vector (CX=Rx, CY=Ry, CZ=Rz)

The above formulas correlates with the TCP configuration setup, which is shown below for reference. To make
it simple, when the “Set Payload” is selected, it is only necessary to take the weight of the object handled into
account.

0.5Kg
Single mount bracket:
Robot payload = 0.09kg(bracket) + 0.65kg(RG2) + 0.5kg(work piece) = 1.24kg
Dual mount bracket:
Robot payload = 0.18kg(dual bracket) + 0.65kg(RG2 master) + 0.65kg(RG2 slave) + 0.5kg(work piece) = 1.98Kg

7.3.3

Depth compensation

When “Depth Compensation” is enabled, the robot arm will try to make a movement that compensates for
the circular movement of the finger arms. There will be a small lag between the RG2 and robot arm
movement. This lag will be dependent on the settings set in the installation, see 7.2.2.4. The compensation
is done along the z-axis, so any manual change that will change the orientation of the z-axis will affect the
compensation.

RG2 TCP node

The RG2 TCP node can be inserted to set the current TCP for the robot. The view and the controls are similar
to the Mounting setup screen. The “TCP radio buttons & values” and “TCP width” is identical to the settings
from the Installation, except that they only affect the single node and not the installation.
For explanation, please see 7.2.1.3 and 0 (if dual Grippers are installed see 7.2.1.5 and 7.3.5).

RG2 Script function

When the On Robot URCap is enabled, there will be a defined RG2 script function:
RG2(target_width=110, target_force=40, payload=0.0, set_payload=False, depth_compensation=False,
slave=False)
All the input arguments are the same as the one used by the RG2 node. The script function is useful for
parameterized programming. For example a relative movement for quick releasing a work piece can be done
like this:
RG2(measure_width+5, 40)
That will open the Gripper 5mm with the target force set to 40N.
And if a soft/compliant work piece needs to be marked with a certain depth(2mm) it could be done with:
RG2(target_width=0, target_force=3, depth_compensation=True)
RG2(target_width=measure_width-2, target_force=40, depth_compensation=True)
