Unitree B1 Review: Specs and Uses of the IP68 Industrial Quadruped Robot

The Unitree B1 is an industrial quadruped robot of about 50 kg with IP68 protection. Unitree does not list a price on the product page. This review covers its specifications, design and uses.

Quick Verdict

The B1 was Unitree's first industrial-grade quadruped and is the predecessor of the B2. Its main features are sealing to IP68, a 20 kg walking load and a large expansion board for payloads: seven Gigabit Ethernet ports and RS485, USB and CAN interfaces, with up to three Xavier NX computers. It walks for two hours on a 932 Wh battery. The newer B2 is stronger and faster, and the page gives no speed or torque figures for the B1.
