The machine in motion
The Unitree Go2 is a four-legged robot, often called a robot dog. It stands about 70 centimetres long and 40 centimetres tall, and weighs around 15 kilograms. The maker, Unitree, builds it for consumers, schools and researchers.
Each leg has three motors, so twelve in total. The body is aluminium alloy with hard engineering plastic. A small laser scanner on the head, called LiDAR, lets the robot see its surroundings.
What it can actually do
The robot walks, trots, climbs stairs and gets back up after falling. Unitree lists a top speed of 2.5 metres per second on the cheapest version. The faster versions reach 3.7 metres per second, with about 5 metres per second measured in the lab.
It can carry about 7 to 8 kilograms on its back, depending on the version. Unitree gives a short-term maximum of 10 to 12 kilograms. Steps up to roughly 16 centimetres and slopes up to 40 degrees are listed as manageable.
The laser scanner covers 360 degrees around and 96 degrees up and down. With the phone app it can build a point-cloud map of a room and then walk a path you set. A follow mode keeps the robot beside you using a wireless tracking tag, at a remote distance Unitree states as over 30 metres in open ground.
Battery life is about one to two hours on the standard 8,000 milliamp-hour battery. The education version uses a 15,000 milliamp-hour battery for about two to four hours. All figures come from Unitree’s own specification table.
Where it stands
Unitree showed the Go2 in July 2023 and opened orders at the same time. The company’s own store sells it directly and lists shipping within about one month, so it is a shipping product, not a concept.
Published prices, before tax and freight, are 1,600 US dollars for the Air version, 2,800 for the Pro and 4,500 for the X. The education version has no public price; Unitree asks buyers to contact sales. A separate hand controller costs extra on the cheaper versions.
Typical buyers are hobbyists, universities and companies testing legged robots. Unitree also sells a wheeled variant called Go2-W and markets larger models for industrial inspection.
What is unclear
Unitree’s launch materials promised a chat feature powered by a large language model. The current product page describes general embodied intelligence instead, and warns that features vary by country. Which conversation features work in which market is not stated clearly.
Speed, payload and battery figures are marked as lab or best-case numbers by Unitree itself. The 4G mobile connection outside mainland China is limited to 43 European countries and some parts of Asia. Unitree does not publish a noise level, a water-resistance rating or an operating temperature range for the Go2.
