I spent $4,000 on a robot dog from China
A tech journalist purchased a Unitree Go2 Pro robot dog for $4,017 to evaluate its practicality and cost-effectiveness. During a test walk in Washington, DC, the robot attracted significant public attention but ultimately collapsed due to battery depletion and overheating. The article highlights how Unitree's low pricing strategy is democratizing quadruped robotics and positioning the company as a major player in the emerging humanoid robot market.
- ▪The author paid $4,017 for the Unitree Go2 Pro robot dog, which is significantly cheaper than similar models available a few years ago.
- ▪The robot dog collapsed near the author's home after its battery dropped to 5% and its internal temperature reached 84°C during an uphill walk in 87°F weather.
- ▪Unitree recently debuted on the Shanghai stock market, with its valuation reaching $34 billion, which is more than triple its pre-IPO value.
- ▪The company leverages its quadruped robot experience to sell humanoid robots for as little as $13,500, making it a global leader in that sector.
- ▪Despite its novelty, the robot has limited practical applications for home use because it lacks arms and is less energy-efficient than wheeled alternatives.
