Before starting please read the safety precautions. |
The Edbot Dream box has been designed to keep the various components together. The key parts are described below. See the parts list at the end of this guide for a complete list.
CM-150 microcontroller.
SM-10 servo motor.
2 x GM-10 geared motors.
Bluetooth module with cable.
Packets of rivets and a round plastic case to store them.
Rivet extraction tool.
Plastic plates, wheels etc. for assembly.
LB-041 rechargeable Li-ion battery.
LBB-041 battery cradle.
Micro USB to USB charging cable that connects the battery cradle to a USB charger (not included).
RC-100 remote control unit - not used by the Edbot Software.
Charge the battery. Your battery will initially contain a small amount of charge for testing and may not have enough power to supply the microcontroller and Bluetooth module. See the charging section for details.
Remove the CM-150 microcontroller from its packaging (it is packed along with the two geared motors). This microcontroller has a built-in buzzer, noise detector and three infrared distance sensors. It has four ports for connecting external equipment. The geared motors connect to ports 1 & 2. Ports 3 & 4 are multi-purpose 5-pin ports for connecting the servo motor and various other sensors and modules (supplied separately).
To switch on the microcontroller first connect the battery, then hold the start button down for a second until it beeps twice. Release the start button. Press the start button again to switch off the microcontroller.
|
It is very important to press and hold the start button until the microcontroller beeps twice. This places it in command mode and enables it to communicate with the Edbot Software. |
Your Edbot Dream is supplied with two motors (GM-10) and a servo motor (SM-10). Connect motors to port 1 / port 2 of the microcontroller using a 2-wire cable. You can control the motor speed and direction. The servo motor connects to port 3 / port 4 using a 5-wire cable. It can operate in wheel mode when it acts just like a motor. It can also operate in joint mode when you can set it to a specific position and read it's current position.
Connect the Bluetooth module to the microcontroller using the supplied cable as shown below. Be careful to connect the cable the right way round. You may find the plug needs a firm push home.
Empty the rivets into the round plastic storage case. The rivets are used to fasten the various components together. You'll need to assemble each rivet before use by clicking the pin into the rivet base.
It is very important to ensure the pin is inserted into the rivet in the correct orientation such that the lugs on the end of the pin are aligned with the slots in the rivet and the pin can freely slide inside the rivet with ease. Failure to align the pins correctly could mean they break or become loose and fall out when the Edbot Dream is in operation. |
When inserting a rivet, make sure the pin is not pushed into the rivet before use. Use the supplied rivet extraction tool to remove a rivet.
The battery has the following properties:
Type: Lithium-ion (Li-ion)
Weight: 50g
Dimensions: 24 x 70 x 27mm
Voltage: 3.7V
Capacity: 1300mAh
A protection circuit module (PCM) is incorporated to protect the battery from overcharge, discharge and excessive current.
The battery is charged in situ. The batteries will be automatically disconnected from your Edbot Dream whilst they are being charged.
Connect the charging cable to the cradle by fitting the micro USB plug into the corresponding socket on the battery 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 1.3A at 5V to give a charging time between 2 and 3 hours.
We provide a link to our PDF assembly instructions for 20+ robots after purchase. They include sample code in Scratch and Python.
You can also view the assembly instructions using the 3D animated R+ m.Design App from Robotis.
Download and set up the Edbot Software. You'll find the product key printed on a label attached to the outside of the Edbot Dream box.
|
Once activated, your product key will be permanently associated with its Bluetooth module. If you have purchased multiple Edbot Dream kits it is a good idea to use colour-coded stickers to link the two together. Place a coloured sticker on the product key label and affix the same coloured sticker to the Bluetooth module. Repeat this for each of your Dream kits using a different colour for each kit. |
