A team of young engineers based in Bengaluru is developing an innovative floating robot designed to address the persistent issue of waste accumulation in local lakes. Incubated at the RV College of Engineering, the startup Scrub Robotics is behind the project known as SCRUB V2.
Unlike traditional lake-cleaning machines that utilize conveyor belts to haul rubbish out of the water, this new model features a simplified design. The device relies on its forward and reverse movement through the water to gather floating debris. As the robot moves forward, an intake opening allows waste to enter, and when it shifts into reverse, the opening seals shut to retain the collected material.
Because this collection mechanism operates without additional motors or powered moving parts, the design aims to minimize energy consumption and reduce maintenance requirements. The startup has previously conducted field testing with an earlier iteration, the SCRUB V1 platform, at Bengaluru's Kengeri Lake in coordination with the Bruhat Bengaluru Mahanagara Palike. Alongside demonstrating floating waste retrieval, the team has also tested capabilities for monitoring water quality.
Urban water bodies across India face significant pressure from pollution, sewage, and inadequate upkeep. Bengaluru, historically recognized for its interconnected network of lakes and waterways, has experienced widespread ecological impacts due to rapid urban expansion. While surface cleaning removes plastics and weeds, experts note that comprehensive restoration also requires addressing untreated sewage, subterranean pollution, and source-level waste management.
Looking ahead, the developers aim to transition their prototypes into practical tools for municipal bodies. Their developmental roadmap includes deploying a floating platform dedicated to gathering water-quality data, as well as introducing a separate system intended to intercept debris within rivers and canals. The ultimate viability of SCRUB V2 in aiding Bengaluru's water bodies will hinge on continued field trials, consistent operational performance, and eventual adoption by local civic authorities.
