Zero-Op Mercenary Automated Paintball Sentry Gun

Like the best of projects, this started with a question- “I wonder if it’s possible…”.

It turns out the answer is YES!, but not without a lot of hard work.  This project alone was my crash course in C++, Linux, Computer Vision, Servo Control, and designing circuit boards.  I can’t think of a more exciting way to learn.  Although I can think of a few less painful ways.

What is it?

The Mercenary is a robot that can ‘see’ the world through a single camera, and can interact with the world by aiming and firing its paintball gun. Basically, the goal is to replicate the behavior of a person guarding an area, with a robotic system.


  1. I wonder if you could post some more specific information. Is the software opensource? Could you post a quick overview of how you designed your targeting algorithm and so on?
