Your Edbot Mini is supplied with two spare rechargeable batteries inserted into the charging cradle.
Carefully take your Edbot Mini out of its case by gripping the main body under the arms and gently easing the limbs out of the foam cut-out. Charge the batteries to full capacity before use. For further information see the next section.
Each battery has the following properties:
Type: Lithium-ion (Li-ion)
Dimensions: 24 x 70 x 27mm
A protection circuit module (PCM) is incorporated to protect the battery from overcharge, discharge and excessive current.
Your Edbot Mini is supplied with two removable, rechargeable batteries: one inserted at the back of your Edbot Mini and one inserted under the chest plate at the front.
Make sure your Edbot Mini is switched off before removing or fitting the batteries.
To remove the back battery, grip both ends of the battery and pull the battery, keeping the battery parallel to the holder.
To remove the front battery first splay both legs 90°. This moves the hip servo motors creating the space to slide the battery out. Grip both ends of the battery and pull the battery downwards, keeping the battery parallel to the holder. Then slide the battery out to one side under the chest plate.
To fit the batteries to your Edbot Mini follow the removing instructions detailed above, ensuring you line up the battery contacts with the battery holder connectors and push the battery into the holder until you hear it click.
The battery charging cradle is comprised of two separate chargers each with its own micro USB socket and adjacent charging LED. You can charge up to two batteries at once with the charging cradle.
Line up the metal connectors on the battery with the contacts in the charging cradle. Keep the battery parallel to the charging cradle and push the battery into the cradle until you hear it click.
Connect the charging cable to the cradle by fitting the two micro USB plugs into the two corresponding sockets on the cradle.
Connect the plug on the other end of the charging cable to a USB charger (not supplied).
Battery charging is indicated by a steady red light on the charging LED. The LED will extinguish when the battery is fully charged.
We recommend using a USB charger that can deliver at least 2.5A at 5V to give a charging time between 2 and 3 hours.
The newer ERM162 Edbot Mini model allows you to charge the batteries in situ. Please note you won't be able to use the Edbot Mini while charging the batteries in this way.
Switch off your Edbot Mini before continuing. Connect the charging cable to the micro USB sockets on the battery holders. You will need to carefully raise the left arm to gain access to the front battery. Connect the other end of the charging cable to a USB charger.
The batteries will be automatically disconnected from your Edbot Mini whilst they are being charged.
Download and set up the Edbot Software. You'll find the product key printed on a label attached to the outside of the Edbot Mini case.
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.
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.
