Hardware overview is in the video with a better description.
Jetson TK1 processes images from the USB webcam and the two Raspberry Pi NoIR cameras then sends commands to the Arduino Mega in order to move autonomously around the environment avoiding obstacles.
The software is custom written and uses OpenCV for image processing. No ROS, no SLAM, no neural nets or whatever.
The idea in short:
I will send a robot around planet earth. The robot will be sent to you free of charge. Let it run in your area for 24h and show all earthlings your projects or a piece of your country. Send the rover to the next destination after your mission is over (postal charges will be refunded).
The robot can be controlled through a web interface while transmitting a live video stream. All young scientist and of course all discoverers that are young at heart get free access to the robots, there is even no registration needed.
I had bought a RC Car from walmart for about $15 to use with the Arduino Motorshield a while back (see here). Fortunately, I had taken some pictures before I removed the RC receiver circuit from it. Turns out that its lot more efficient to use the onboard controller along with an Arduino instead of using a motorshield. I didnt some research and found out that many “cheap” RC cars use the same Realtek TX2 & RX2 chips inside. I was lucky enough to find the same inside this RC car.
