Here is the comparison of the Unitree B2 and Unitree Go2 EDU on the three attributes you asked about:
| Attribute | Unitree B2 | Unitree Go2 EDU |
|---|---|---|
| Max payload | 120 kg | 12 kg |
| Top speed | 6 m/s | 3.7 m/s |
| Battery runtime | 6 h | 4 h |
Summary: The B2 leads on all three metrics — it carries 10× the payload (120 kg vs 12 kg), reaches a higher top speed (6 m/s vs 3.7 m/s), and runs longer per charge (6 h vs 4 h). The Go2 EDU is the lighter, more compact option at 15 kg vs the B2's 60 kg, but on payload, speed, and runtime, the B2 is the stronger performer across the board. unitree.com +5unitree.com ↗“robot.payload_kg=120 kg”unitree.com ↗“robot.max_speed_m_s=6”unitree.com ↗“robot.battery_runtime_h=6 h”unitree.com ↗“robot.payload_kg=12 kg”unitree.com ↗“robot.max_speed_m_s=3.7”unitree.com ↗“robot.battery_runtime_h=4 h”
