The Unitree B2 Basic Kit with Battery and Navigation Kit is Unitree's B2 industrial quadruped sold as a bundle: the Basic B2 kit, a battery and a navigation kit on one order. That bundle is what separates this listing from the plain Unitree B2 listing, which is for the robot itself. It suits inspection and field teams who already know they want navigation on the robot and would rather specify it once.

The robot is the full-size B2: about 60 kg with its battery, about 1098 × 450 × 645 mm standing and about 880 × 460 × 330 mm lying down. Unitree rates it for a walking load above 40 kg and a standing load of at least 120 kg, with about 360 N·m of joint torque. It climbs continuous stairs of 20–25 cm, goes up and down 40 cm stairs in the forward direction, crosses obstacles up to 40 cm and handles slopes above 45°. Running speed is above 6 m/s in special configurations; in practice speed is limited for safety.

The B2's battery is a 45 Ah, 2250 Wh pack at 58 V that changes quickly. Unitree gives more than 5 hours and over 20 km of walking without load, and more than 4 hours and over 15 km with a 20 kg load. The body is rated IP67 and operates from -20 °C to 55 °C, and Unitree aims the B2 at power inspection, emergency rescue and industrial inspection, including long stairs, rock piles and steep slopes.

The kit name covers the Basic B2 kit, the battery and the navigation kit, and nothing else should be assumed. The navigation kit's sensors, computer and software, and the number of batteries supplied, are confirmed with the quotation. Unitree notes that some functions need human operation or secondary development and that figures vary with configuration and application, so settle those details against your route before ordering.
