ESRES Tech deploys fully automated, remotely monitored robotic systems for underwater sludge cleaning, industrial sediment removal, and hazardous environment maintenance — keeping your operations compliant and efficient.
Our robotic platforms handle hazardous, high-depth, and confined environments where human entry is dangerous or impractical.
Fully automated robots navigate sediment pools, lagoons, and basins using SONAR, LiDAR, and vision mapping to agitate and extract accumulated sludge without halting plant operations.
Precision robotic systems access confined sumps and pits, removing sediment and contaminants safely while providing real-time data on material composition and volume.
Automated internal tank inspection and cleaning for oil & gas, chemical, and power industries. Our robots map the interior before cleaning, producing a verified sludge profile report.
Long-range telemetry via LoRa and XBee spread-spectrum communication. Real-time underwater mapping with inertial navigation, providing accurate sludge profile data before, during, and after cleaning.
Integrated agitator and vacuum pump systems lift and route removed material for safe disposal or processing, maintaining environmental compliance at every step.
Detailed pre and post-cleaning reports with quantified sludge data, helping heavy industries maintain regulatory compliance and demonstrate environmental responsibility.
Our system is powered by a remotely operated hydraulic power pack, completely eliminating electrical hazards in hazmat, explosive-atmosphere (ATEX), and confined-space environments. No live electrics underwater — making it the safest solution available for high-risk industrial sites.
A front-mounted, hydraulically driven rolling-blade drum delivers high-torque mechanical agitation directly to compacted sludge beds. The helical blade geometry ensures continuous material breakup across the full drum width, with no electrical components near the working head — even in the most corrosive or explosive atmospheres.
A sealed suction hood beneath the agitator drum captures agitated material the moment it is loosened. The same hydraulic circuit drives the extraction pump, routing sludge through reinforced hoses to surface-side collection — a single, unified mechanical loop with no secondary power source required.
A ruggedised edge AI processor analyses multi-sensor data in real time — fusing depth maps, obstacle detections, and sludge density readings to make autonomous decisions without relying on surface connectivity. Machine learning models trained on sediment behaviour adapt cleaning intensity dynamically for maximum efficiency.
SONAR, LiDAR, and Inertial Navigation System data are fused through a vision-based SLAM pipeline, giving the robot a precise real-time map of its environment — including sludge depth profiles — regardless of water visibility or turbidity.
Chirp spread-spectrum radio (LoRa / XBee) maintains a robust command and data link over long distances and through industrial RF interference, allowing full remote monitoring and override from the surface control station at all times.
ESRES Tech is a robotics and automation company based in Bandel, West Bengal, specialising in robotic systems for industrial cleaning in hazardous and underwater environments.
Our team combines expertise in embedded systems, mechanical engineering, and computer vision to develop robots that replace human workers in dangerous confined-space and underwater cleaning tasks — improving safety, reducing costs, and maintaining environmental compliance.
We work across heavy industries including oil & gas, chemical processing, power generation, and municipal infrastructure, providing tailored robotic cleaning solutions for the most challenging environments.
