Powering and Programming Interface

Note: This tutorial is applicable for Kerloud Flying Rover equipped with Raspberry Pi model 4

The onboard Raspberry Pi can be powered by either the battery or the provided power adaptor. We highly recommend users to use the power adaptor as the power source for programming, so as to avoid overdischarge of the battery. The power and HDMI ports are shown in the figure below. Both HDMI ports can be used for display.

📌 Overdischarge of the 6S battery to voltage under 21v or lower can lead to permanent damage.

By connecting the Raspberry Pi with a screen via the provided mini HDMI cable, we can log in the onboard computer. We advise users to use screens with native HDMI ports. The default user name and password are both ubuntu. We installed the QTcreator as the default IDE for software programming. To launch the Qtcreator interface, just enter qtcreator in a terminal.

To create a new qt project for a ROS package, users can import existing source code as shown below:

Users can also log into the computer remotely. To achieve this, both the Raspberry Pi and a remote PC have to be in the same local wifi network. Suppose the IP address for the Raspberry Pi is 192.168.0.101, then we can log into it with commands:

    sudo apt update
    sudo apt install openssh-server
    ssh ubuntu@192.168.0.101
