Uber Eats uses four-wheeled robots to handle the final stretch of food delivery. Fixing underground water pipes usually means digging up roads and sidewalks -- a process that's disruptive and expensive. However, researchers at the University of Sheffield in the U.K. are working on a different approach. They've developed small robots called "Pipebots" that can travel inside water pipes to find and potentially repair leaks, all without any excavation.

The world of robotics is expanding with every passing day and now, robots will be used to keep a watch on pipe networks in England and Wales. According to the water industry economic regulator Ofwat, England and Wales lose around three billion litres of water due to water pipe leaks and the robots can be the solution to these problems. Scientists told BBC that the miniature robots will patrol the pipe network and produce constant updates about any potential leaks or damages.
