Use Rosbot

1. You need to enable the serial port and disable serial console on your Raspberry Pi. You can config in the desktop perference or use command line sudo raspi-config then go to Interfacing Options > Serial to enable the serial port.

2. Set the jumpers next to USB port on the Rosbot to RPI mode.

3. Install the communication firmware to your Rosbot. You can find the firmware in this repository and we provide a helper script to install the firmware to your Rosbot. You can run the following command to install the firmware.

python arduino_upload.py

Press the reset button on the Rosbot and you will see the following message in the terminal.

bootloader  0.4 4
cpu name: ATmega328P
flash 0/31213
flash 128/31213
flash 256/31213
flash 384/31213
.....

To verify the firmware is installed correctly, you can run the following command to check the serial port. The M2 command will turn on/off the LED(Pin13) on the Rosbot.

echo "M2 13 0\r\n" > /dev/ttyAMA0
echo "M2 13 1\r\n" > /dev/ttyAMA0
