Section 2: Setup of the Delta Robot Back to Table Of Contents
2.1 Unfolding the Robot Collection Net
1. Place the robot on top of your table tennis table. (Photo 2-1)
2. Carefully fold apart both sides of the net at the same time until the first stop. The net bars
will be horizontal at this point as shown. (Photo 2-2).
2.2 Positioning the Support Legs
1. Swing the curved tubular Support Legs outward toward the front of the robot into position
(Photo 2-3), approximately 6-8 inches apart.
2.3 Rotating/Raising the Throwing Head into Play Position
The flexibility of being able to adjust the throwing height of the Delta robot allows for a very
realistic match experience. By adjusting the height (from one of four different positions)
together with the ball trajectory settings, you can have the robot throw you any type of ball
from a low fast serve to a high lob.
Photo 2-1
Photo 2-3
Photo 2-2

Power Pong User Manual Page 6
Note: If you are unpacking the unit for the first time, remove the rubber bands used on the
throwing head which protect the Deflector Plates during shipment.
When adjusting throwing head height, always be sure that one of the 4 painted rings is slightly
above the Ball Feed Tube Locking Assembly. Failure to adjust the height properly can lead to
throwing malfunctions, including throwing two balls simultaneously.
1. Loosen the Throwing Height Adjustment Knob found on the rear of the Ball Feed Tube
Locking Assembly typically one-half to one turn. (Photo 2-4)
2. Grasp the curved Ball Feed Tube and rotate approximately 180° so that the ball head / exit
route is pointing toward you and/or the front of the robot. You may have to pull up slightly
on the Ball Feed Tube to rotate. See Photo 2-5 (before) and Photo 2-6 (after).
3. Pull the head upwards on the Ball Feed Tube until the second ring on the tube is just visible
(Photo 2-7). SLIGHTLY tighten the Throwing Height Adjustment Knob to hold the throwing
head in place - just enough to prevent it from dropping.
Caution: Overtightening can damage the Ball Tube!

Power Pong User Manual Page 7
The height of the throwing head can be adjusted to one of four possible heights as shown in
photos 2-8 thru 2-11. Before tightening the Throwing Height Adjustment Knob, it is important
that one of the Ball Feed Tube rings be located just above the Ball Feed Tube Locking Assembly.
Never operate the robot with the height beyond the 4th red ring.

2.4 Connecting the Throwing Head Communication Cable
1. Connect the Communication Cable coming from the Throwing Head Assembly to the 15-pin
connector found on top of the robot base (Photos 2-12, 2-13 and 2-14).
2. Tighten (snug) the two thumb screws on the cable connector. Note: This cable MUST be
disconnected anytime you swing the table support legs back into their transport position to
prevent damage to the cable.
2.5 Fully Opening the Collection Net
1. Standing behind the robot, grip the top points of the net and completely fold the net down
on both sides until the net fully opens (Photo 2-15).

2.6 Mounting the Robot on the Table
1. From behind, grasp the robot with both hands on the bottom of the base. Pick up the robot,
angle the Support Legs downward, and slip them under the end of your table. (Photo 2-16)
2. Gently push the robot onto the end of the table with the Power Pong logo aligned with the
center line of the table. (Photo 2-17)
3. Carefully let go of the robot base and it will hang securely by its own weight.
4. Lower the Corner Brackets of the net around the corners of your table.
5. With a newer robot, the corners of the net may not stay completely down at this point –
this is okay and as the material loosens up the corners will stay in place.
Note: If the table to which you are attaching the robot to, is the table that you will always use,
you can secure the mounting by using the included longest Velcro strip to secure the robot to
the end of the table. You may also use supplied Velcro on the corners of the table.
2.7 Adjusting the Support Legs (Rubber Tips)
The Delta robot is designed with adjustable Support Legs allowing it to fit onto tables with a
variety of thicknesses, up to 1 inch. There are adjustable rubber tips on the end of the Support
Legs that can be turned clockwise or counterclockwise, as needed for your table, so that the
Throwing Head Assembly is positioned straight up and NOT tilting either forward or
backward. Failure to adjust the legs properly will cause ball placement to be inaccurate.
1. Turn the adjustable rubber tips on the ends of the Support Legs as needed so that the Ball
Feed Tube is straight up, not tilting forward/backward. (Photo 2-18, Figures 2-1, 2-2)

2.8 Securing the Side Nets
1. Pull one of the Side Nets along the side of the table and secure to the net post hardware
(Photos 2-19 and 2-20), by looping the rubber band over the top of the net support and
then down around the clamp screw that holds the net support onto the table.
2. Repeat with the other Side Net.
2.9 Connecting the Control Panel Cable
1. Connect either end of the Control Panel Cable into the jack (looks like a headphone jack) on
the side of the Robot Base Assembly (Photo 2-21). Be sure to fully seat/insert this cable.
2. Extend the other end of the Control Panel Cable to the opposite side of the table and
connect to the Control Panel (see Photo 2-22 and 2-23). Be sure to fully seat/insert this
cable.

2.10 Mounting the Control Panel to the Table
The Control Panel Bracket and Control Panel can be mounted on either side of the table.
1. Attach the Control Panel Bracket onto the side of the table, near the end so that you can
easily reach/operate it. (Photo 2-24)
2. Attach the Control Panel to the mounting tabs on the Control Panel Bracket. You may use a
Velcro strip to help secure the bracket onto the side of the table if you will always be using
the same table. (Photo 2-25)
2.11 Connecting the Delta Robot to a Power Source
1. Insert the power connector from the power adapter into the power jack on the side of the
Robot Base Assembly. (Photo 2-26)

Section 3: Delta Control Panel Back to Table Of Contents
3.1 Control Panel Introduction (Photo 3-1)
The Delta Control Panel is used to control all aspects of
how the balls are thrown/delivered to you. This includes:
•placement of the ball on the table
•speed, spin, and trajectory of the balls
•starting/stopping and the rate of ball delivery
•programming Drills and Clusters
•the use of random placement/ball type features
This section of the User Manual focuses on the function
of the individual buttons, dials, and LEDs that are part of
the control panel. References to Drills (which are grouped
sequences of balls) and Clusters are used in this Section,
however those functions will be covered in greater deal, in Section 4.
3.2 Controls Affecting the Single Thrown Ball
3.2.1 Ball Select Buttons / LEDs (Figure 3-1)
There are eight Ball Select buttons and eight Ball Select LEDs across the top of the Delta Control
Panel. The eight Ball Select buttons are used for several purposes including:
1. Adding a Ball to a Drill –To add a ball, press a Ball Select button for a ball number (1-8)
that is not in use (LED above the button OFF). The ball will become “active” and the Ball
Select LED above the button will begin flashing ON/OFF. Attributes (PLACE, SPEED, SPIN,
etc.) from the previously “active”ball will automatically be copied to the just added ball,
however it can be modified as needed at this point.
2. Removing a ball from a Drill –To remove a ball that is in use, hold the Ball Select button
down for at least two seconds, for the ball you wish to remove. The corresponding Ball
Select LED will turn OFF indicating that the ball is no longer in use.
3. Making a ball “active”–To edit the attributes of a ball that is already in use (LED ON),
the ball must be made “active”. Do this by pressing the Ball Select button once, briefly.
The corresponding LED will begin flashing ON/OFF and you can now edit the ball’s
attributes.
4. Removing all the balls in a Drill –Pressing both the Ball 1 and the Ball 8 Select buttons
and holding for 2 seconds will remove all the balls from a Drill –along with their
settings, in one step.
Below is a summary of the eight Ball Select LEDs and the status that they provide:
OFF –The corresponding ball is not programmed and is not currently being used
ON Yellow –The corresponding ball is currently in use
ON GREEN –The Ball Select LEDS for Ball 1 and Ball 2 can be ON with GREEN color in
addition to Yellow. The GREEN indicates that the ball is configured as a Serve ball and as a
result, will have a short time delay before it is thrown.
Photo 3-1

Power Pong User Manual Page 14
Flashing ON/OFF Yellow or Green –The corresponding ball is “active”, and its settings can
be configured and/or changed.
3.2.2 1-S and 2-S Buttons (Figure 3-2)
Ball 1 and Ball 2 have additional functionality and can be designated as SERVE balls. Doing this
provides an added delay before the ball is thrown. To make Ball 1 or Ball 2 a SERVE ball, press
the Ball 1-S or Ball 2-S Select button twice rapidly. The Ball Select LED will start flashing ON/OFF
GREEN to indicate that the ball has now successfully been designated as a SERVE and is
“active”. This means the attributes for the SERVE can now be set. When saving the Drill, the
SERVE designation WILL be saved. To turn this SERVE designation OFF, press the 1-S and/or 2-S
button twice rapidly.
3.2.3 PLACE Buttons / LED Display (Figure 3-3)
The left/right PLACE buttons are used to set the placement of the ball, related to the centerline
of the table. When the Green “G” LED is lit on the PLACE LED Display, the ball will be delivered
approximately down the center line of the table. Press the left PLACE button to have the ball
Figure 3-2
Figure 3-1

Power Pong User Manual Page 15
delivered left of the center line or press the right PLACE button to have the ball delivered right
of the center line. Additional presses of the left/right PLACE button will cause the ball to be
delivered further to the left/right of the center line. The PLACE LED display will always provide
you with an indication of the ball placement of the table.
3.2.4 TRAJECTORY Buttons / LED Display (Figure 3-4)
The Trajectory buttons raise or lower the “active”ball trajectory (throw angle). One short press
of either button will change the trajectory by about one-half degree, either up or down. If you
hold either button down (long press), the change in trajectory can be made rapidly. The
Trajectory LED display will update with major changes (8 or more short presses) of the
trajectory button.
3.2.5 SIDE-SPIN (DEG) Buttons / LED Display (Figure 3-5)
The SIDE-SPIN (DEG) buttons change the direction and amount of side spin on the “active”ball.
When the “0” LED is illuminated, there is no side spin on the “active”ball. Pressing the
left/right SIDE-SPIN buttons, will change the amount of spin and whether the spin is left or
right. The Side-spin LED will update with each click (left or right).
