The RAIN-Hex is designed to be an advanced Walking Machine Centre with enhanced mobility (speed and adaptation with different leg layout), machining capability (work volume and stiffness) and versatility (deploy different tools/sensors).

The RAIN-Hex has demonstrated the advanced machining and walking capabilities with customised leg-layout configurations during its preliminary testing stage. The current industry use case is to deploy the RAIN-Hex for in-situ sampling for inspection of pressurised water reactor with industrial partner Rolls-Royce Power Engineering plc.
