DIY Pipe Inspector Goes Where No Bot Has Gone Before
Originally published on hackaday.com by Dan Maloney on 27 November 2024
Stargate System built an innovative homebrew sewer inspection robot to tackle a plumbing nightmare in a 50-year-old house. The sewer line had a persistent blockage, worsened by a 120-degree bend near an old joint. This configuration left traditional inspection cameras ineffective, prompting Stargate to construct a compact, remotely operated vehicle (ROV) that could navigate the tight and unpleasant environment. The bot’s 3D-printed ABS hull was sealed with acetone for waterproofing and featured gear motors for mobility, with upgraded drive tracks replacing the original wheels after testing.
A Raspberry Pi Zero powered the robot, controlling the camera and lights. Connectivity and power were managed through an Ethernet shield with a custom PoE system. The compact design allowed it to fit in the pipe and maneuver around the bend, capturing footage that revealed the blockage’s extent. Stargate even improvised a chain flail tool to break apart large obstructions and restore the pipe’s flow.
The footage, while not for the faint-hearted, highlights the robot’s success in addressing the issue. This clever solution showcases how makers can apply ingenuity and robotics to solve unique and challenging real-world problems, even in the most inhospitable environments.
