Technical information

Edbot server

An Edbot connects to a Bluetooth enabled computer. The Edbot Software running on this computer is configured as a server. This server can support multiple Edbots. You can configure more than one Edbot server on a network, but each Edbot should be connected to one and only one server.

As a server the Edbot Software:

  • Connects to Edbots - it connects to any number of Edbots using a Bluetooth wireless connection.

  • Handles requests - it handles requests from your program to control each connected Edbot.

  • Controls access - it assigns control of each connected Ebot to the selected client.

Edbot client

The Edbot Software automatically runs in client mode looking for Edbot servers on the network. This is true whether the software is configured as an Edbot server or not. This mode is specifically designed to forward Scratch requests to the Edbot server. You should run the Edbot Software on all computers where Scratch is used. If you aren't using Scratch then you only need to run an Edbot server.


You will find your product key on your Edbot carry case.

After successful activation, the product key is permanently associated with that specific Edbot.

The same product key can be used on a different computer on a different network with the same Edbot. This flexible licensing approach allows the Edbot to be used in different locations.

Example setups

See topology diagrams below for more information.

Edbot architecture

The Edbot Software is a client/server application developed using Java. The main components are:

  • Main control window - provides a list of configured and discovered Edbots and a message pane.

  • Server setup window - used to configure an Edbot server which handles API and plugin requests.

  • Plugins window - used to configure languages such as Scratch which are unable to use the Edbot API.

See architecture diagram below for more information.

Network settings

Port Numbers

Edbot clients connect to the Edbot server via a system service port number. The default for HTTP is TCP/IP port number 8080. This works for standard client/server networks. However, if your network setup requires an alternative port number for the Edbot service, the Edbot server port number is edited in:

Edbot server >App > Server Setup > Settings.

See example screen shot below.


If your network is operating a firewall, it may have closed or restricted access to system service ports to increase network security. The Edbot service requires the permission to accept incoming requests from client computers. To grant permission the system service port must be opened.

To do this go to the Ports and Services section in your firewall application and add Edbot server as a system service with the TCP/IP port number set in Server Port.

Install Edbot Software

Install Edbot Software on all computers that will access your Edbot.

After downloading the latest version of Edbot, run the installation program and follow the on screen instructions to install Edbot on your computer.

Network installation

If installing across a network, depending on your setup, you may be able to run an unattended software install using the following setup command line parameters:

*/SP /verysilent *

The installation does not require a restart.

Enter [Edbot installation program name] /? at the command line for more help.

Upon launch, the Edbot Software will scan for Edbot robots and Edbot clients and display results in the Messages pane at the bottom of the window. See example screen shot below.

Install programming languages

Install the programming languages you plan to use, for example, Scratch or Python, on all computers that will access your Edbot. This provides the tools and libraries to write programs.

Connect your Edbot robot to the Edbot server

Connect Edbot via Bluetooth

To do this, your Edbot server will need to have Bluetooth enabled. Some computers, such as laptops have Bluetooth built in. If your computer is not Bluetooth enabled, you can plug a USB Bluetooth adapter into the USB port on your computer.

Turn on and login to the Edbot server computer.

Turn on your Edbot robot using the on/off toggle switch located at the back of the shoulder area. At initial start-up all Edbot’s servo LEDs will flash red once and its Bluetooth LED, located in the shoulder area, will blink blue continuously. Your Edbot is now discoverable to Bluetooth devices.

On a Windows 7 computer select the Start > Control Panel > Hardware and Sound > *Device Manager. *

Locate Bluetooth in the list of devices and right click.

On the dropdown menu click Enable and close Device Manager.

Select the Start > Control Panel > Hardware and Sound > Add a Device.

Select ROBOTIS BT-210 and click Next.

The ROBOTIS BT-210 will need to be paired with your computer, this means you need to enter a four digit code to connect.

Click Pair and enter the passcode 0000.

Click Next.

Your Edbot will be listed as ROBOTIS BT-210 Paired.

Your computer and Edbot will usually automatically connect anytime the two devices are in range of each other with Bluetooth turned on.

When successfully connected the flashing blue LED on Edbot will change to steady blue LED. If your Edbot does not connect automatically see Section 8 Troubleshooting.

Name your Edbot

During the configuration you will be asked to name your new Edbot. Choose the name carefully because it will be its name for life. The name you choose will be encrypted and linked to all the programmes written for your Edbot – like a finger print!

There is no limit to the length of the name, however, a short name (less than 10 characters) is recommended. You could name your Edbot after a famous character, make up an acronym based on your school name or take inspiration from Roald Dahl and make up a new word, use your imagination and have fun with this. To get you thinking, here are the names of some famous robotic characters:

  • Wall-E (Waste Allocator Load Lifter – Earth class)

  • R2-D2 (Robotic 2nd generation Droid series 2)

Or more humanoid robots like

  • C-3PO

  • Data from Start Trek

Start-up LEDs not flashing – check batteries

Servo motors with a steady red LED on start-up – this indicates a problem with the servo motor. Turn the Edbot off, when the servo motors have become passive, gently manipulate the affected servo back and forth, and turn on again. If the servo motor still has a steady red LED on start-up repeat the process, turn the Edbot off, remove the batteries, gently manipulate the affected servo back and forth, refit the batteries and turn on again. This should clear the issue, if the problem persists report it to Robots in Schools Ltd.

Edbot not connecting to Edbot server via Bluetooth – check the following settings:

  • Check Edbot server has Bluetooth connectivity turned on.

  • Check Edbot is turned on and blue LED is flashing.

  • Check Edbot is within Bluetooth transmission range of 10 metres (30 feet).

  • Run a scan for Bluetooth devices.

  • If Bluetooth on Edbot server requests a pairing code, enter 0000.
