Boston Dynamics Spot vs Unitree Go2: The Professional System Meets the Affordable Quadruped

Spot weighs 33.8 kg, stands 61 cm and carries 14 kg. The Go2 weighs 15 kg and carries 8 kg. The Go2 is faster, though: 3.5 m/s against 1.6 m/s. Both have 12 joint motors and both run briefly: Spot about 90 minutes on a 564 Wh battery, the Go2 about 1.5 hours on a 230 Wh pack.

The difference shows in toughness. Spot has an IP54 enclosure and an operating range of −20 to 55°C, which lets it work on a construction site or in a mine. The Go2 is lighter and more agile, but the manufacturer offers it as equipment for people, not for full-shift work in harsh conditions. In return the Go2 has a 4D LiDAR with a 360°×96° field of view, an HD camera, voice control based on a GPT-type model and gaits trained with reinforcement learning, features rarely seen at this price. Spot offers a mature software ecosystem, charges in an hour and, according to the manufacturer, lasts 180 minutes in standby. The Go2 comes in three variants: Air (entry level), Pro (stronger motors and sensors) and EDU (for research, with a full SDK and ROS2), so when comparing with Spot check which variant is meant. The Go2's camera and LiDAR call for attention regarding GDPR, which we cover in “Data Security: Robots with Cameras and the GDPR”.

The Go2 in its Air version starts at about USD 1,600 (Unitree's site), the Pro at USD 2,800, and the EDU version at about USD 11,190. Spot cost USD 74,500 according to 2020 data, which today equals about PLN 288,777 (≈ EUR 66,060); the manufacturer does not publish a price. At starting prices the difference is about 46-fold.

In Polish shops the numbers look different: the Go2 Air costs PLN 9,900–12,000 (≈ EUR 2,260–2,740) (deltarobots.com, drony.net, Botland, x-kom), the Pro about PLN 21,400 (≈ EUR 4,900) (Komputronik, drony.net), and the EDU Standard PLN 35,900 (≈ EUR 8,210). So here the gap to Spot is about 25-fold. Even the most expensive Go2 configurations with an extra LiDAR (PLN 105,000–115,000 (≈ EUR 24,020–26,310)) cost less than half of Spot's estimated price. Differences between shops run to a few thousand zloty, so check the exact variant and kit. You can buy the Go2 from several shops and get an invoice. Spot has no confirmed distributor in Poland. More about the Go2 and prices is in “Unitree Go2 Review: Prices and the Air, Pro, X and EDU Versions”.

For a school and a university the Go2 is the obvious choice: cheap, available, with an EDU version and ROS2, and enough for technical demonstrations. It also suits light algorithm testing and simple inspections. The Go2 EDU costs PLN 35,900 (≈ EUR 8,210) in Poland, about one eighth of Spot's estimated price.

Spot makes sense where the robot is to work every day for years: industrial inspection, documenting progress on a construction site site, patrols in security. You pay for support, deployment history and the ecosystem. We know of no documented Spot deployments in Poland, however. A Polish example of an inspection robot is the MAB Robotics Honey Badger 4.0, used in Poznań's channels, and an overview of uses is in “Quadruped Robots: Uses in Inspection, Security and Industry”.
