6 Actuator Contact and Motion

6.1 Actuator Contact

WARNING: Excessive pressure to the DUT surface during test can damage the Actuator

Attachments and the DUT.

Figure 8 Figure 9

To properly make contact with the DUT surface lower the Actuator Carriage along the Z-Axis

using the red handled toggle on top of the Carriage Tower. The Actuators are spring loaded and

should only be lowered enough to make contact. Make sure a gap remains between the

Actuator tip and the bottom of the Actuator Capsule, as shown in Figure 8 and Figure 9.

6.2 Linear Motion

PT3 allows for linear motion with a single Actuator or up to eleven Actuators at 1.5 cm center to

center spacing, as shown in Figure 10.

To create a linear motion interaction with the DUT;

1. Install and position the desired Actuator Attachments.

2. Lock the R2-Axis in at 0 deg.

3. Position the DUT using the R1-Axis so the desired linear motion path is parallel to the Y-Axis.

4. Position the Actuators over the starting target by adjusting the X-Axis and Y-Axis

5. Once the Actuator is in the desired starting position lock the X-Axis using the break on the

Carriage Tower.

6. Check that the linear motion path is parallel to the Y-Axis by moving the Actuator to the end

target; if the path is parallel the actuator will end over the ending target. If the actuator

does not end over the ending target repeat steps 3 through 6 until it is.

7. Return the actuator to the starting target

8. Contact the DUT surface with the Actuator, using the Z-Axis

WARNING: Excessive pressure to the DUT surface during test can damage the

Actuator Attachments and the DUT.

9. Move along the Y-Axis until you reach the end target

10. Lift the Actuator off the DUT surface, using the Z-Axis

6.3 Arc Motion

To create an arc motion interaction with the DUT;

1. Install and position the desired Actuator Attachments.

2. Using the X-Axis, Y-Axis, and R1-Axis position the Actuator over the starting target, than lock

the X-Axis, Y-Axis, and R1-Axis




4. Using the R2-Axis move the Actuator to the desired end target

6.4 Pinch Motion

Converging and diverging pinch motion can be achieved using the Pinch Actuator Attachment.

1. Install the Pinch Actuator Attachment

2. Move the Actuators to the desired starting separation

3. Align the Pinch Actuator Attachment over the desired DUT surface location




5. Move the actuators to the desired ending separation


7 Trouble Shooting

7.1 Z-Axis Motion

If the Z-Axis motion does not move freely in both direction check to make use the Z-Axis break is

completely loosened. The knob for the Z-Axis break is located on the front of the Carriage Tower

and needs to be turned counterclockwise to loosen.

7.2 Actuator Tip is stuck

If the actuator tip becomes stuck in the up position, check to make sure there is enough space

provided between the tip and the actuator capsule during DUT surface contact. See section 6.1.

8 Maintenance

8.1 Replacing Finger Tip Fabric

Before each use of the tool the fabric tip of the actuator should be inspected. If the fabric is

tattered, warn, dirty, or no longer holding to the shape of the finger tip, it should be replaced.

To replace the fabric you will need:

• A pair of sharp scissors

• New conductive fabric

LessEMF.com part number: A321

• Heat Shrink

i. Remove the old fabric and heat shrink form the tip of the finger.

ii. Clean the brass tip of the finger, the tip should be free of dirt and any residue from the old

fabric and heat shrink.

iii. Cut a piece heat shrink

iv. Cover the tip of the actuator with an oversized piece of fabric

v. Slide heat shrink over the tip and fabric to hold fabric in place while cutting

vi. Cut the fabric just below the heat shrink

vii. Slide the heat shrink over the cut edge of the fabric

viii. Use the heat gun to shrink the heat shrink

WARNING: The fabric will melt if overheated. Only head the tip enough to shrink

the heat shrink, but not enough to melt or discolor the fabric.

8.2 Linear Guides

Grease forms a lubricating film between steel balls and the rolling surface of linear guides

reducing friction. Grease loss and deterioration will cause shorter life of linear guides. Apply

grease appropriately depending on your condition of use.

Recommended Lubrication Intervals: Every 6 months or Every 3 months when travel distance is

extensive, or every 1000km of travel distance. If grease deterioration and contamination is

severe in your operation condition, grease application intervals should be shortened.

Recommended Grease:

- Pinch attachment linear guide: Multemp Grease PS2 by Kyodo Yushi Co., Lid.

- X-Axis and Y-Axis linear guides: Alvania Grease S2 by Showa Shell Sekiyu K.K.

- Z-Axis Ball Spline: Alvania Grease S2 by Showa Shell Sekiyu K.K.

If the recommended grease is not available Kyodo Yushi LRL3 grease is a recommended

substitute. Kyodo Yushi LRL3 grease can be purchased form Misumi and is part number GAV400-

LRL3-A. When changing the grease type, it is recommended to wipe off the old grease then

apply the new grease.
