assembly 7


Lay your Edbot Mini down on a clear, flat surface with a minimum size of 2m². Your Edbot Mini needs a relatively smooth surface with some friction to operate. A wooden or melamine desk or vinyl floor is ideal. It doesn't like rubber surfaces or carpets - and no it isn't a Dalek! Ensure your Edbot Mini is in the starting position. See below.


Make sure the shoulder servo motors are not over-rotated 360°: the cables connecting the shoulder servo motors should be loose, allowing the shoulder joints to move freely.

Switch on your Edbot Mini using the slider switch at the rear of your Edbot Mini behind the shoulders. The servo motor LEDs should flash red once. If they flash red five times the batteries need to be recharged, see Charging. You should see a red light on the micro-controller indicating the power is on. Your Edbot Mini's Bluetooth module will now flash blue, indicating it is trying to make a Bluetooth connection. Make sure the Edbot Software is running and configured. Press the connect button. After a few seconds the Bluetooth module should display a steady blue light, indicating it is connected.

Your Edbot Mini is now ready to run your code!

The batteries should last for an hour or more during normal operation.

Switch off your Edbot Mini between active sessions. Your Edbot Mini does not have to be kept on continuously during a classroom session, when students are busy coding and not ready to send their programs to the robot. After switching on press the connect button in the Edbot Software to reconnect.

Note if the servo motors are switched on they will still use power to maintain their position, even if they are not moving.

After use

Switch off your Edbot Mini and carefully move the servo motors so that your Edbot Mini can fit into the foam cut-out inside the Edbot Mini case. See the diagram. Gently push your Edbot Mini back into the foam cut-out making sure the servo motor cables do not snag before closing the case and storing it safely away.
