1. Scope of delivery & assembly
Scope of delivery
Robot incl. mains assembly, power cable and power supply unit (input: 100~240 V, output: 24 V), remote
control.
Other parts included: Allen key (2 and 4 mm) for ejector discs, tting piece for ejector wheels, spare
rubber rings for ball catcher net, Velcro strip, white spare steel strip for deector plate, table holder for
optionally purchasable tablet.
Assembly
1. Place the robot on the table tennis table and fold down both sides of the net until they lock at about 45°
(picture 1). Then turn the retaining hooks out to a distance of about 20 cm (picture 2).
2. While holding the head with the other hand, carefully loosen the locking screw behind the ball tube
(picture 3) and turn the head 180° so that the ejector points exactly towards the centre line. Pull the head
upwards until the second ring can be seen slightly above the guide tube (picture 4). Then tighten the
locking screw again to x the height.
!CAUTION: Do not overtighten the screw or damage to the tube may occur.
3. Now lift the robot with both hands and angle it slightly so that the retaining hooks can be guided
under the table frame. Guide the robot to the edge of the table and then set it down carefully (picture 5).
Connect the cable of the ejector head to the interface of the base (picture 6).

!ATTENTION: The GEWO Omega Nexxt robots are preset for tables with a 25 mm surface. To ensure
a good grip and a clean ball ejection even with thinner surfaces, the retaining hooks are equipped with
a height adjustment at their upper end. If necessary, turn the adjustment heads upwards enough to
compensate for the difference in surface compared to the 25 mm of the standard setting.
iTIP: If necessary, you can attach the longest of the Velcro straps supplied to the back of the table
surface to additionally x the robot head to the table.
4. Now fold down the ball net completely.
5. Pull the side ball nets along the side edge of the table to your net. First pass the rubber loop under-
neath the net set (picture 7) and then fasten the rubber loop to the adjusting screw of the respective
net post.
6. Then attach the corner caps to the edges of the table and connect the Velcro fastening strip of the
net to that of the respective bracket at the corners of the table to provide additional stability (picture 8).
iTIP: If necessary, the two short Velcro strips can be additionally attached to the corner caps to give
the net even more support.

7. Connect the power supply unit to your mains
supply and connect the plug to the
connector on the side of your robot (picture 9).
8. Fill at least 50 clean table tennis balls into the
ball catching area before you start playing.
2. Operation
Adjust the head height
To simulate the real game as well as possible,
the robots of the GEWO Power Pong Nexxt series
offer the possibility to adjust the head height. To
do this, hold the ball tube rmly with one hand
and loosen the large black wing screw with the
other hand.
Afterwards, the tube can be adjusted to a diffe-
rent height by pushing or pulling it slightly.
To select a different height, make sure that one
of the silver rings at the transition of the lower
tube is slightly visible (picture 10) before tightening the screw again.
!CAUTION: Do not overtighten the screw, otherwise the tube may be damaged. Tighten the screw only
at the 4 marked positions. Incorrect head height can lead to ball blockages, incorrect ejections or other
problems.
Download the Power Pong app
As preparation before using the GEWO Omega Nexxt robot for the rst time, you should install the Power
Pong app on your mobile device. This requires a connection to the internet. The app is available to you
free of charge in both the App Store for iOS and the Google Play Store for Android. Use the following QR
code/link to get to the download.

Connect the robot to the smartphone/tablet
Now connect your mobile device to the robot via Bluetooth. To
do this, select the „Connection“ tab and tap on „Scan“ to
search for GEWO Omega Nexxt robots in the vicinity. Then tap
on your Omega robot in the list to connect it to your terminal
(picture 11). Once the connection is established, you will return
to the exercise overview.
If you cannot nd your robot in the list, there are different
methods of troubleshooting:
1. Make sure that the Bluetooth connection on your terminal is
properly switched on. Disconnect the Bluetooth connection once
and activate it again.
2. Check if the robot is already connected to another device.
Your GEWO Omega Nexxt robot can only be connected to one
device at a time. If you want to use another device with
your robot, rst disconnect the existing connection before
establishing a new connection.
3. If you still cannot nd your robot, close the app on your end
device and start it again and try to connect the robot again.
4. Disconnect the robot from the power by unplugging the power supply and wait at least one minute
before plugging the power supply back in to restart the robot. And try again to see if you can connect
your robot.
5. If restarting the robot does not help, restart your terminal once.
6. If all the above methods fail to achieve a connection, please test if you can connect another device to
your robot.
7. If the robot cannot be found even from other terminals, please contact your GEWO dealers.

Centring the robot
Now select the exercise Test Drill 1 under the drills tab in the
Power Pong App and tap on Start Exercise.
Now balls should be ejected along the centre line. If the balls do not
land on or near the centre line of the table, stop the exercise, loosen
the black locking screw on the tube of the robot head and turn the
head carefully. Now tighten the locking screw again and repeat the
steps until the balls land as close to the centre line as possible.
!ATTENTION: If the robot has not been properly centred before
playing, it is possible that balls will not land on the table during
some exercises!
Exercise overview – tagging, organising, sharing
and copying exercises
(Picture 12) In the exercise overview you can see all the exercises
stored on your device. This also includes the 45 preset exercises. If
you want to nd a specic exercise more quickly in the list, use the
search function, which you can open via the magnifying glass at the
top right of the screen. In the search you can search your exerci-
ses either by name or by the tags assigned to your exercises (# +
handle of the exercise) (picture 13). Another way to nd specic
exercises is to tap on a tag under one of the exercises shown. This
opens the search function directly and the exercises are ltered
according to the respective tag.
iTIP: Tags are a great way to organise your exercises. Assign
tags such as „serve“, „topspin“ or „backspin“ to your exercises so
that you always have quick access to suitable exercises.
To enter the editing mode, tap on one of the exercises and hold
your nger on the screen until the background turns green (picture
14). Once you are in edit mode, you can mark more exercises by
tapping them briey and unmark them again by tapping marked
exercises again.
All marked exercises can then be added to an exercise grouping via
the 3 dots at the top right of the screen. To do this, tap on „Add to
group“ and select all the groupings to which you want to add the
marked exercises. You can also use the „+“ sign to create a new
grouping. When you have selected all groupings, tap on „Conrm“ to
conrm your selection.

In addition, marked exercises can also be copied with the „Copy“ but-
ton, sent with the „Share“ button or irrevocably deleted with „Delete“.
If you want to leave the editing mode again, tap on the „x“ in the top
left-hand corner.
To create a new exercise now, tap on the large „+“ symbol at the
bottom right of the screen.
Exercise settings – random and mirrormode, inter-
val training and ball frequency
(Picture 15) If you want to add a new ball to an exercise, tap on the
blue button „Add ball“. Then the ball settings open for the newly
added ball. (see page 10).
Below the „Add ball“ button there are 4 further settings with which
the exercise can be changed.
The „random“ mode ensures that the balls stored within an exercise
are ejected in random order. This mode is necessary if you want to
train realistic irregular exercises with the robot.
The „mirror“ mode mirrors the balls of the congured exercise.
This setting has two benets. Firstly, an exercise created for right-
handers or left-handers can be adapted so that it can also be played
with the other hand. In addition, a second practical side function is
that a completely new exercise can be created quickly and easily.
For example, a forehand exercise can be changed to a backhand
exercise in a matter of seconds.
With the „duration“ mode, the exercise is given a timer. You can
select a playing time between 10 seconds and 10 minutes by tapping
on the time display (picture 16, see page 10). As soon as the selec-
ted time has elapsed, the robot stops the exercise. If the „duration“
mode is activated, „break“ can also be activated to switch to interval
training. The time display to the right of the break switch indicates
how long the pause time is after the selected playing time has elap-
sed before the exercise starts again. Like the playing time, the break
time can also be adjusted by tapping the display from 1 second to 5
minutes by tapping on the display.
Among the 4 selectable settings is a BPM control with which the ball
ejection speed can be congured. Speeds between 10 and 120 balls
per minute can be set here.

Above the table shown in the picture is another bar. Here you can
see the name of the exercise. This can be changed with a tap.
To the right of the name is a diskette that can be used to save
changes and 3 dots.
Tapping on the 3 dots opens another menu. Tags can be added to
the exercise or the exercise can be assigned to a group, copied,
shared with friends or deleted.
If you are in a pre-programmed exercise view, there is also a
screen icon on the right side next to the table shown. Tapping
on it will take you to a YouTube video in which the exercises are
presented by professional junior players.
When all the necessary settings have been made, you can start the
exercise with the help of the green button „Start exercise“.
Ball settings - placement, trajectory, speed, spin
and IFC
(Picture 17) If you want to adjust a ball within an exercise, rst select
the ball by clicking on it. When you have selected a ball, the selected
ball is marked by a yellow frame and the respective selected ball
settings become visible.
Now you can make 6 different settings for your ball:
The placement of the ball on the table can be adjusted via „drag
& drop“. To do this, tap the ball and drag it to your desired landing
point. This can also affect two of the other settings: „Trajectory &
Speed“. The length of the balls played depends largely on „Trajec-
tory“, „Speed“ and spin. By moving the length via drag & drop in a
new exercise, trajectory and speed are adjusted so that the balls
are always played correctly.
However, the „Trajectory“ can now still be changed if necessary via
the controller on the right-hand side next to the table shown.
Settings between 0 (at ejection) and 175 (high ejection) are possible
here. After changing the trajectory for the rst time, a small shadow
circle is always displayed on the scale (picture 18).
This shadow circle indicates the necessary trajectory to achieve
the desired placement with the selected speed and spin values.
The 4 controls „Tempo“, „Spin“, „Sidespin“ and „Delay“ are also
located under the table shown.
