Max Kern has taken a Raspberry Pi Zero W, a camera module and some power circuitry and sensors and created a first-person viewpoint wheeled security drone, the ZeroBot Pro, an upgrade from the previous ZeroBot (without the Pro!). The software UI has been created using Node.js and Socket.io and the motors are controlled using PWM through the pigpio library. The hardware is packed inside a delightful 3D-printed chassis and he has open-sourced the whole design. The STL files are available on Thingiverse and he has uploaded a custom Raspbian image with all the software pre-installed which is available here on Hackaday.io, along with all the instructions you’ll need to build the robot. A brief walk-round of the robot can be seen below:
