The TX2 kernel will need to be rebuilt to enable support for the FTDI converter on the Arduino.

Follow these instructions. Before ./makeKernel.sh, execute this:

sudo sed -i 's/.*CONFIG_USB_ACM.*/CONFIG_USB_ACM=y/' /usr/src/kernel/kernel-4.4/.config

And then finish the instructions.

Finally: sudo apt-get install arduino arduino-core

Upon attaching an Arduino to the TX2, a device named beginning with ttyACM should be listed in your /dev/.

rosserial

sudo apt-get install ros-kinetic-openni2-camera
sudo apt-get install ros-kinetic-openni2-launch
sudo apt-get install ros-kinetic-rosserial-arduino
sudo apt-get install ros-kinetic-rosserial

Find your IP with: hostname -I (case sensitive)

Add the following to your ~/.bashrc:

export ROS_IP=<IP>
export ROS_HOSTNAME=<IP>
export ROS_MASTER_URI=http://<HOST IP>:11311

And then: source ~/.bashrc

Acquire HOST IP from hostname -I on the ground control computer. See Rainbow Dash Ground Control
