The Topsky GAJQRXL-LTZS is a quadruped firefighting and emergency response robot built for load transport, hose deployment, and remote operation across varied and difficult terrain. Sharing the same core specification profile as the GAJQRPP-BLTZS platform — 880 × 640 × 550 mm dimensions, a weight under 150 kg, a rated load capacity of 150 kg or greater, and a 1,500 N minimum traction force — the GAJQRXL-LTZS is designed for missions where a robot needs to move heavy equipment, drag hoses, and transmit live audio and video under IP67 environmental protection. A 500 mm wading depth and obstacle crossing height of 220 mm or greater support operation in wet, debris-laden, or structurally complex environments typical of industrial and wildland firefighting scenarios.

The platform's modular architecture and secondary development expansion interface allow mission-specific payloads and sensors to be integrated, making the GAJQRXL-LTZS adaptable to a range of emergency response and industrial safety configurations. Remote control with audio-video transmission allows operators to conduct reconnaissance, check hazardous areas, and support incident command decisions without exposing personnel to direct risk. With a maximum linear speed of 1.5 m/s or greater, climbing ability of 70% grade or steeper, and straight-line travel deviation under 0.5%, the robot is suited to coordinated emergency logistics and support roles in challenging outdoor and industrial environments.
