Robot dogs are moving into industrial inspection, but navigating a factory is only part of the job. They also need to collect useful data, complete reliable missions and integrate with site workflows. ROBOT24.com compares six quadrupeds across inspection capability, autonomy, mobility, payload, endurance and deployment evidence to assess which best suit different industrial environments.

The Robots Behind the Rankings

1. ANYbotics ANYmal X: ATEX/IECEx Zone 1 IIB; IP67

Overall score: 93.5/100

ANYmal X leads for hazardous-area inspection because it combines explosion-protected certification with a purpose-built inspection payload and autonomous data collection. Documented tools include 20× optical zoom, thermal imaging, microphones and 360-degree LiDAR.

Its certified Zone 1 IIB application is decisive where explosive atmospheres prohibit ordinary equipment. This is a specialized industrial platform; certification scope, temperature limits and deployment configuration must be checked for the exact site.

2. Boston Dynamics Spot: 14 kg payload; published API

Overall score: 91.0/100

Spot offers a mature inspection ecosystem, repeatable missions, supported sensor additions and developer interfaces. Manufacturer documentation provides a 14 kg payload limit, making it adaptable to multiple inspection arrangements.

Its 90-minute average runtime is relatively short and its IP54 ingress rating is below the IP67 level published for several rivals. Runtime changes with payload, so a buyer should validate endurance with the intended thermal or acoustic inspection stack.

3. DEEPRobotics X30: IP67; -20 to +55 C

Overall score: 84.5/100

X30 is designed for inspection and industrial mobility. The manufacturer specifies IP67 protection, -20 to +55 C operation, 45-degree stair capability and 2.5–4 hours of continuous operation.

Its inspection outcomes depend on the installed sensors and software. Public material supports the base platform and industry positioning more strongly than specific, independently measured anomaly accuracy or intervention rates.

4. Unitree B2: More than 40 kg walking payload; IP67

Overall score: 80.0/100

B2 combines unusually high carrying capability with long unloaded or moderate-load walking endurance. Unitree publishes greater than four hours walking with a 20 kg load, IP67 protection and optional autonomous charging.

Unitree notes that some functions require human operation or secondary development. A capable platform is not the same as a verified end-to-end industrial inspection offering, so inspection analytics and site workflow integration should be assessed separately.

5. DEEPRobotics Lynx M20Pro: IP67 Pro; hot-swappable batteries

Overall score: 76.0/100

The M20 Pro configuration combines wheeled travel and articulated legs, LiDAR perception and a hot-swappable battery concept. The Pro column is differentiated from base M20 in the manufacturer comparison and provides industrial-environment versatility.

The base M20 figures, including 15 kg payload and IP66 rating, must not automatically be assigned to Pro. Independent inspection mission results and exact-Pro payload/endurance comparisons remain limited in the reviewed sources.

6. MagicLab MagicDog-W: 10 kg maximum payload; 2–4 h

Overall score: 62.0/100

MagicDog-W blends wheel-leg mobility with cameras, LiDAR and mounting options. MagicLab lists a 10 kg maximum payload and two-to-four-hour operating range, making it a flexible platform for custom instrumentation.

The manufacturer presents inspection as an application, but exact-model deployed industrial reporting, validated autonomous inspection completion and a published industrial ingress rating were not established. It ranks lower on turnkey inspection proof, not on basic mobility alone.

The best fit depends on the application

ANYmal X has the clearest advantage for certified hazardous-area industrial inspections; Spot is compelling for mature inspection workflows and integrations. X30 and Unitree B2 are powerful industrial platforms with different endurance and payload priorities, while Lynx M20Pro and MagicDog-W may suit more customized deployments.
