Substation patrol in winter: which quadrupeds are IP67 and still operate at -20 °C or colder?

Question

Rapidflare · Accepted Answer

Four quadrupeds are rated IP67 and still operate at -20 °C or colder:

**IP67 quadrupeds rated to -20 °C or colder**

| Robot | IP rating | Operating temperature | Battery runtime | Onboard Jetson |
|---|---|---|---|---|
| Ghost Robotics Vision 60 | IP67 | -40 °C to 55 °C | 3.15 h | NVIDIA Xavier 32GB |
| Unitree B2 | IP67 | -20 °C to 55 °C | 6 h | NVIDIA Jetson Orin NX |
| PUDU D5 | IP67 | -20 °C to 55 °C | 2.5 h | NVIDIA Jetson Orin AGX 64GB |
| PUDU D5-W | IP67 | -20 °C to 55 °C | 3 h | NVIDIA Jetson Orin AGX 64GB |

- **Ghost Robotics Vision 60** is the only one rated well below -20 °C. Its lowest operating temperature is -40 °C, which matters if your winters regularly get colder than -20 °C.
- **Unitree B2, PUDU D5 and PUDU D5-W** are rated down to exactly -20 °C, so -20 °C is their limit.

**Robots that didn't make the list:**
- **Addverb Trakr 5** is built for inspection and security patrols, but its IP67 rating is optional and its lowest operating temperature is 5 °C.
- **Unitree Go2 EDU** is only rated down to 5 °C.
- **ANYmal C**, **DEEP Robotics Mini** and **Xiaomi CyberDog** don't have an IP rating or operating temperature listed in the catalog, so I can't say whether they meet your requirements.
