Unitree and Deep Robotics dominate the robot dog market, and we have compared their models in our Go2 and Lite3 guide and industrial inspection guide. But in 2026 European buyers can also choose from Galileo, PUDU and Faraday Future, with models ranging from compact patrol robots to 118 kg platforms that carry 100 kg.
This guide compares these alternatives on size, payload, protection and intended use.

Why look beyond Unitree and Deep Robotics?
Alternatives matter for three reasons: heavier payloads than mainstream models, specialised versions such as explosion-proof or wheeled designs, and a second source for fleets and long projects.

Galileo: from compact to heavy industrial
Galileo C1 is the compact model, with a 48 V, 960 Wh battery, autonomous charging and a low-power standby mode listed at a year or more, which suits remote patrols. Galileo E1 adds a dual computing architecture with ARM and x86 processors and a 1,440 Wh battery; E1-W puts wheels on its feet for faster travel on flat ground.
Galileo S1 is a heavy industrial platform: 1,200 x 550 x 650 mm, 118 kg, dual batteries totalling 3,540 Wh, speeds up to 3.5 m/s, slopes of at least 30 degrees, 3.5 to 5 hours of runtime and a continuous walking load of 100 kg. Galileo EX-1 is an explosion-proof version weighing 120 kg with a 30 kg load and 2 hours of runtime; for EU hazardous areas, ask for ATEX or IECEx certification of the exact model.
PUDU D5 and D5-W
Better known for service robots, PUDU entered the industrial quadruped market with PUDU D5: 900 x 543 x 572 mm, 61 kg, IP67, an operating range of -20 to 55 °C, 250 mm steps and 30-degree slopes. D5-W is the wheel-legged version for large sites.
Faraday Future FX Aegis
Faraday Future’s FX Aegis family targets security, education, research and companionship, with Wi-Fi and 5G, high-power drive modules, battery swapping and autonomous patrol and follow modes. The range spans Edu, Pro and Ultra versions plus wheel-legged models.
