Gecko Robotics TOKA 4
Our Verdict: Revolutionizing tank and vessel inspection with data-dense thickness mapping that manual methods cannot match.
The Gecko Robotics TOKA 4 is a magnetic wall-climbing robot that performs ultrasonic thickness mapping of steel structures including storage tanks, boilers, pressure vessels, and ship hulls. It drives across vertical and overhead steel surfaces using powerful magnetic wheels, taking thousands of thickness measurements per hour.
The robot’s cloud-based Cantilever platform processes the collected data into detailed thickness maps and corrosion heatmaps, identifying areas of wall thinning and predicting remaining asset life. This data-driven approach transforms inspection from a periodic checkbox into a continuous asset integrity management program.
