AI Robot replaces humans in dangerous canal cleaning in Thiruvananthapuram — Here’s how G-SPIDER works

In a major step towards eliminating manual scavenging and ensuring the safety of sanitation workers, the Thiruvananthapuram Municipal Corporation has introduced G-SPIDER, an AI-powered robotic canal-cleaning system, at the Amayizhanchan Canal near the railway station premises in Thampanoor.

The Amayizhanchan Canal — particularly the covered stretch beneath Thampanoor Railway Station — presents serious operational challenges due to restricted vertical clearance, continuous water flow, confined working conditions, and the absence of safe human entry points. These conditions have long made routine cleaning and maintenance extremely difficult through conventional methods.

To address these challenges, the AI-powered robotic system was commissioned by Local Self-Government Minister M. B. Rajesh.

The initiative is the result of a collaboration between the Thiruvananthapuram Municipal Corporation and Technopark-based Genrobotic Innovations, the developers of the well-known robotic scavenger Bandicoot.

Officials said the introduction of this advanced robotic system would eliminate the need for sanitation workers to enter dangerous and unhygienic environments. They described the initiative as a groundbreaking move that enhances operational efficiency while significantly strengthening safety standards in waste management.

The G-SPIDER Automated Canal Cleaning Robot, developed by Genrobotic Innovations, is designed to operate in complex and high-risk canal environments without human entry. Built on a Cable-Driven Parallel Robotics (CDPR) architecture and powered by AI-enabled vision and sensor intelligence, the system can precisely detect, assess, and remove accumulated waste.

Using advanced machine vision, the robot autonomously identifies and adapts to different waste types, water flow conditions, and structural constraints in real time. Its five-degrees-of-freedom robotic mechanism, equipped with a biomimetic claw-type grabber, allows accurate positioning and secure handling of mixed and irregular debris.

The extracted waste is directly transferred into designated collection vehicles, enabling a fully hands-free canal-cleaning process — from detection and extraction to safe disposal.

The deployment of the G-SPIDER robotic system marks a transformative step in urban sanitation management. By automating canal cleaning, the technology significantly improves worker safety by reducing exposure to toxic gases, contaminated water, and hazardous waste.

"The robot is designed to function efficiently even during high water levels and continuous flow conditions, ensuring uninterrupted maintenance of urban waterways. It can safely extract mixed and hazardous waste, including plastics, sharp debris, and other harmful materials, thereby improving sanitation standards," the statement said.

Through scheduled and systematic cleaning, the robotic intervention also enhances drainage efficiency, helping prevent urban flooding and contributing to a cleaner and safer urban environment.

The deployment of the G-SPIDER Automated Canal Cleaning Robot represents a decisive shift towards safe, mechanised, and technology-driven canal maintenance. By eliminating the need for workers to enter hazardous spaces, the initiative protects sanitation workers’ lives while improving operational efficiency and strengthening sustainable urban infrastructure.

Officials said the system also serves as a scalable and replicable model that could be adopted for other high-risk canals and drainage networks across the state.

Aligned with the vision of the Swachh Bharat Mission, such technology-driven interventions demonstrate how cities are increasingly embracing innovation to modernise sanitation systems while prioritising the dignity, safety, and well-being of sanitation workers.
