Arduino Robot (Italy)

Description:

The Arduino Robot is the first official Arduino on wheels. The robot has two processors, one on each of its two boards. The Motor Board controls the motors, and the Control Board reads sensors and decides how to operateEach of the boards is a full Arduino board programmable using the Arduino IDE.

Both Motor and Control boards are microcontroller boards based on the ATmega32u4. The Robot has many of its pins mapped to on-board sensors and actuators.

Programming the robot is similar to the process with the Arduino Leonardo. Both processors have built-in USB communication, eliminating the need for a secondary processor. This allows the Robot to appear to a connected computer as a virtual (CDC) serial / COM port.

As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. This means you can learn exactly how it's made and use its design as the starting point for your own robots. The Arduino Robot is the result of the collective effort from an international team looking at how science can be made fun to learn.

Power:

The Arduino Robot can be powered via the USB connection or with 4 AA batteries. The power source is selected automatically,The battery holder holds 4 rechargeable NiMh AA batteries.

Note: Do not use non-rechargeable batteries with the robot.

For safety purposes, the motors are disabled when the robot is powered from the USB connection.

The robot has an on-board battery charger that requires 9V external power coming from an AC-to-DC adapter (wall-wart). The adapter can be connected by plugging a 2.1mm center-positive plug into the Motor Board's power jack. The charger will not operate if powered by USB.

The Control Board is powered by the power supply on the Motor Board.

Both of the Robot boards have a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.

Input and Output:

The Robot comes with a series of pre-soldered connectors. There are a number of additional spots for you to install additional parts if needed.

All the connectors are labelled on the boards and mapped to named ports through the Robot library allowing access to standard Arduino functions. Each pin can provide or receive a maximum of 40mA at 5V.

Programming:

The Robot can be programmed with the Arduino software (download). Select "Arduino Robot Control Board" or "Arduino Robot Motor Board" from the Tools > Board menu, The ATmega32U4 processors on the Arduino Robot come preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the AVR109 protocol.

You can bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) heade.
