An Indian engineering graduate, Pulkit Gaur, has developed a robot that can go underwater and clean water or chemical tanks. This project is developed by Gridbots, an entrepreneurial venture by Gaur, this low-cost robot will remove any sludge particles in water. "This compact machine has tracks fitted for movement. It has a drive system on the front side to which a brush mechanism is attached to scratch dirt from the tank walls. We are also considering using a filter," said Gaur to Bangalore Mirror.

This robot is available for consumers as well. This robot is available at Rs. 15,000 to Rs. 20,000, and is a consumer version of SaUsR, the robot that is already in use in medicine industries. These robots are targeted at those who make medicines. They employ them to prevent sludge formation in tanks. "SaUsR carries out underwater operations with ease and lets you use this robot as a sophisticated underwater cleaning unit. It has on-board intelligent electronics that lets it navigate in fully-autonomous mode. With a high resolution on-board camera having pan-tilt c
