DEEP Robotics' Jueying X50 runs 2 km with 50 kg on its back, 2.5 times what its X30 carries

DEEP Robotics (云深处科技), the Chinese quadruped maker, launched the Jueying X50 on Nov. 6 for emergency firefighting and power-grid work. The company says the robot carries a 50 kg load on the move without a bigger body, and can run more than 2 km at 3 m/s with that load on its back, The Paper reported.

That is a different job from the one its X30 industrial quadruped does. The X30 is rated for 20 kg of continuous payload and a top operating speed of 2.5 m/s, according to its product page. Fifty kilograms is 2.5 times that, and the uses DEEP Robotics lists for the X50 are about hauling: hydraulic tools, insulator strings and grounding-wire sets for line crews, tens of kilograms of firefighting gear carried into a fire, a hose that keeps spraying, and life detectors, breaching tools and medical supplies for rescue teams, according to Wenhui. The X50 is meant to be the crew's pack animal.

To get there over rough ground, DEEP Robotics fuses lidar point clouds with IMU data and uses a reinforcement-learning controller to pick footholds. It says the X50 can climb onto 80 cm ledges one after another, cross stepping stones 70 cm apart, climb open-riser stairs, and hold its stance against the recoil of a fire hose.

Rainbow Robotics is selling the same buyers on price

The same week, Korea's Rainbow Robotics showed its RBQ quadruped at RoboWorld 2026 climbing onto a 1 m platform without jumping, then hopping down, the Robot Newspaper reported. A company representative said the base model costs nearly half as much as the market's leading product, and that commercial rollout starts next year, aimed at defense, police, private security, firefighting and rescue. DEEP Robotics is pitching what the robot carries; Rainbow is pitching what it costs.

The range figure covers a sprint

The one loaded range DEEP Robotics gives is short. Two kilometers at 3 m/s takes about 11 minutes, which fits the run from a fire truck or a substation gate to the work site. The X30 page quotes about 2.5 hours of endurance under load. How long the X50 lasts at walking pace with 50 kg aboard will decide whether a grid crew sends it out for a whole inspection round or only for the first trip in.
