Thank you for purchasing Cruzr with the Zorabots Operating System (ZBOS).

Cruzr is an autonomously moving robot, that listens to voice-commands and responds or acts accordingly. It can move to a location, start apps on the tablet or say the current weather report for example. The software for Cruzr has been designed to be highly customizable when interacting with humans (i.e. Kiosk app), can be used to ask customers for feedback (i.e. Survey app) and can navigate a map once it has been learned.

In addition to these (basic) functions, Cruzr can also move the arms while speaking, to ease the interaction with humans. This feature is also reflected in the composer-page of ZBOS Control (the app used to configure compositions on the robot). In the composer-page, the user can manually move the limbs to certain predefined positions while in the middle of speech or while playing a video on the robot.

The most useful feature would most definitely be the ability of the robot to move (somewhat) freely on a stored map. This map can be customized to fit the environment, and can be adjusted with points for the robot to move to or contain virtual walls to limit the area Cruzr is allowed.

A specialised edition with additional temperature-monitoring was created. For more information, see Epidemic edition

Limitations of the Lidar system

The following limitations apply to the used lidar system and subsequent mapping process:


  • Sight distance (or object-detection) of 16m

  • Maximum length and/or width for a map is 100m (theoretical area = 10000m²)

  • Highly recommended surface area for the map is 1000 m²

  • Detection of the LiDAR at 12 cm height above the floor

  • Passageways must be at least 95 cm wide

Material restrictions

The following limitations apply to the detected material

The LiDAR signal is ineffective against glass, stainless steel and pure black materials.
For glass walls, 6cm wide opaque materials should be attached, centering at a height of 12cm.
The RGBD sensor is ineffective against black light-absorbing materials and glass.
The ultrasonic sensor is ineffective wave-absorbing materials (e.g. acoustic absorbing or foam materials).
The ground IR is ineffective against complex surfaces (e.g. checkered surface in black/white or stainless steel)


The following examples could cause problems for being detected

  • Glass wall

  • Borderless table

  • Desk Chairs

  • Table and chairs with stainless steel legs

  • Stainless steel and black-and-white surfaces

  • Steps/objects lower than 12 cm

  • Passageways that are too small


Cruzr will stop at the entrance of the passageway or Cruzr will get stuck partway in the passageway. The passageway must be at least 0.95m to allow Cruzr to pass through safely.

Recommendations for mapping

ZoraBots recommends using the following procedures when creating a map:

  • Stay behind the robot when creating/updating a map

  • Drive close to the walls / reflective surfaces to improve the data quality

  • Drive in a straight line as much as possible

  • Drive slowly so the map is filled in completely after one or two pass(es)

  • Turn the robot a full 360 degrees (while staying behind the robot) at regular intervals

  • Create virtual walls to contain the robot and/or to create safety-zones where the robot really shouldn’t go

Getting started

This section will describe how to start using your Cruzr robot.

Please keep the original box in case the robot ever needs to be shipped.

Initial setup

Once the robot has been connected to the charging station and is charging, the initial setup can be performed. Push the On/off button (see the Back View) to turn Cruzr on.

Once the robot has been turned on for the first time, the initial setup will start. This setup contains the following steps:

  1. Selecting a language for the setup

  2. Setting up the wifi (optional)

Language Selection

The first step is to select the language the robot will use. By default English, French and Dutch are available.


This language will be used for:

  • The remaining setup-display (display-language)

  • The language James will listen to (voice-commands)

  • The default language when rebooting the robot (initial microphone configuration and display)

  • The subsequent default-language for starting kiosks and/or voice-commands (These options can be changed later in the settings)

Configuring the WiFi

The next step is to configure the WiFi. Tap the name of the prefered network, enter the password and tap the button Connect.

When re-running the initial setup, the wifi information doesn’t need to be entered if the network is known.

Connecting to the robot

Finally, a page containing the information to connect to the robot is shown.


Scan the QR-code shown in ZBOS Control to connect to the robot. For more information, see the manual for ZBOS Control (Manual ZBOS Control)

Interacting with Cruzr

There are several ways to interact with Cruzr (especially during games or custom compositions), but the main control-method is by using voice commands, by using the tablet or by using the ZBOS Control app.

Power options

Powering Cruzr on

Use the following steps to power Cruzr on:

  • Tap the power-button at the bottom if the robot isn’t powered on yet.

  • Hold the power-button at the back of Cruzr down until the main light is flashing.
    Release the power-button to power on Cruzr.

Powering Cruzr down

Use the following steps to power Cruzr down:

  • Swipe down the screen with at least 3 fingers to show a screen asking for a PIN-code

  • Enter the password (by default: 111111)

  • Tap the option 'Just once' when asked which launcher to use to start the link

  • Tap the power-button in the top-right corner of the Ubitech default launcher

  • If a popup is shown asking to shut down, tap it to shut the robot down
    Otherwise, hold the power-button at the back of the robot to shut it down

Emergency shut-down procedure

Use this option only in emergency.

Tap the power-button at the bottom of the robot to shut the robot down

Voice Commands

Cruzr can be controlled (to a certain extent) by using voice-commands.

Cruzr will listen to pre-programmed voice commands after the wakeword OK Cruzr has been understood. Stand in front of the robot for the best results.

If the setting Rotate the robot when hotword is recognized is enabled, the robot will even turn to the source of the sound.


The following speech-related settings can be found in the advanced-section of the settings.

  1. Listen to voice-commands

  2. Rotate the robot when hotword is recognized


The microphone at the bottom of the home-screen on the tablet can also be used as an indicator to see if Cruzr is listening.

Not listening



Prerequisites for the voice commands

Not all voice commands can be used all of the time, the following conditions must be set in order to use (some) voice-commands.

  • Settings of the robot

The setting 'Spoken commands' in the general settings needs to be turned ON before the robot will respond to the wakeword "OK James" and start listening.

If the option 'Spoken commands' is off, the option 'Rotate the robot when hotword is recognized' will be greyed out and unable to be changed.
  • Internet

Certain features require an active internet-connection to retrieve the latest data and to keep up-to-date (e.g. Weather, Verklizan or installed apps).

  • VoIP

In addition to having a connection to the internet, a stable connection is needed to make calls using VoIP-services (the minimum bandwidth needed for a VoIP-call is between 85 and 100 kpbs). The section VoIP / SIP in the settings has been created to enter the account-information needed to call the Verklizan helpcenter (or any other VoIP-service). A SIP-account needs to be registered at Verklizan before any VoIP-calls to their help-center can be made.

Voice Commands

The following is (an extract of) the list of voice-commands.

Advanced features

Cruzr also features the following additional settings:

  1. Turn to the source of the voice

    • Cruzr will turn to the direction of the voice if the wake-word has been understood and the option ‘Rotate the robot when hotword is recognized’ is enabled.

  2. Display the command in the kiosk

    • If the kiosk-app (home screen) is active, the recognized command will be displayed on the tablet.

  3. Start an activity when no input has been detected

    • Cruzr can start an activity (composition, moving to charging station, …​) if no input has been detected by the user for some time. This action can then be stopped by any user-interaction (speech, tapping the tablet, …​)


Kiosk app

The Kiosk app is the default launcher for Android-powered ZoraBots-robots (e.g. James/Cruzr). This app is used as:

  • Main display

  • User-interface to configure features

  • Platform to launch other apps

For more information, see the Kiosk-manual

ZBOS Control app

The ZBOS Control app (avaiable for iOS or Android-devices) can be used to control Cruzr. This app can be used to create custom compositions or kiosk-datasources and manually control Cruzr.

In addition to the app, an online platform ( is also available for registering and controlling a Cruzr-robot.

For more information on using ZBOS Control or the online platform, see

By using the online platform, you agree to our Terms and Conditions for use.

Epidemic edition

This specialised edition was created to aid in epidemic prevention.

Cruzr scans people safely to check for elevated temperature and face mask. When certain configured conditions are met, an alarm is generated which can then be the trigger for a series of actions performed by the robot, or notifications pushed to ZBOS Control so that staff can take appropriate measures.

The robot has been equipped with an additional thermal camera (see Specifications) to perform these tasks.

Camera 1

Required software

The following apps need to be installed on the Cruzr Epidemic:

  • App 'Temperature' (by UBTech)

  • ZBOS Kiosk v1.5.1+

  • ZBOS RAIL v1.4.1+


The following features were specifically designed for this version of Cruzr:

Temperature monitoring

The thermal imaging camera will scan the face of every person passing by the camera. If the scan-results indicate that the conditions are met (e.g. detected temperature is higher than threshold or face mask is worn incorrectly), a photo will be taken of the person and an alarm-event will be sent to the robot and any connected ZBOS Control app.

Capturing photos may not be available in your region due to local privacy legislation. For example, in EU this feature is not activated in order to comply with GDPR-regulation.

The photos will be only be stored for a predefined interval on the robot, and when available, pushed to a cloud storage account.

Customizable options in ZBOS Control

Tap the gear-icon (ionicon gear) in the toolbar of the Monitoring-page in ZBOS Control to display the available options for the alarm-events:




If this option is checked, an alarm will be sent when people are wearing their face mask incorrectly (or not at all).

Retention Days

Set the time for how long the images and alarm-events will remain stored locally on the robot.



If enabled, an alarm will be sent when someone has been detected with a body temperature higher than the threshold.

Retention Days

Set the time for how long the images and alarm-events will remain stored locally on the robot.

Temperature threshold

Set the minimal detected temperature before an alarm will be sent (in degrees Celsius °C).

Tap the check-button (md check) in the top-right corner to apply the changes for new events.

Additional options

Each alarm-event will be sent with certain properties, which can be used to filter the list of events in ZBOS Control. Tap the filter-option (md funnel) in the Monitoring-page in ZBOS Control to display the available options:


Filter by Type

Tap to toggle the display of alarm-events for:

  • Temperature-events

  • Mask-events

Filter Mask alarms

Tap to toggle the display of alarm events:

  • Yes: Someone was detected wearing a face mask correctly

  • No: Someone was detected wearing no face mask at all

  • Incorrectly: Someone was detected wearing a face mask incorrectly

This will only change the display of the items in ZBOS Control, the list of triggered events will still be available on the robot.

We sincerely hope Cruzr will provide a valuable service to your home or business. Hopefully you will continue to provide us with the desired features or bugs which occurred in the workplace, so we can keep improving and expanding the product.
