The AgileX RANGER is an omnidirectional UGV capable of navigating both indoor and outdoor environments with a payload capacity of 100 kg, extendable to 150 kg with specific configurations. It reaches speeds of 2.6 m/s with up to 8 hours of runtime. Four-wheel independent suspension handles slopes exceeding 10 degrees, and a hot-swap modular battery system minimizes downtime with fast charging capability. The modular architecture supports free module combinations, T-slot rails, CAN bus protocol, and open-source SDK for research, industrial, and logistics applications.
