Overview

The Expedition A3 is a humanoid robot from Chinese company AgiBot (Zhiyuan Robotics), distinguished primarily by dynamic, athletic movements such as jumps and martial arts demonstrations. It is positioned as an interactive service and demonstration robot.

Design

The A3 stands 173 centimeters tall and weighs 55 kilograms. It is constructed from a lightweight combination of magnesium, titanium, and TPU, resulting in a power-to-weight ratio of 0.218 kilowatts per kilogram. The body features a flexible waist joint designed to replicate the rotational and lateral movement of the human torso. The legs utilize a lightweight, exoskeleton-like structure intended to combine explosive movement with stable landings. The arms can handle loads up to 3 kilograms, with tool center point speed reaching up to 2 meters per second. On a single battery charge, the A3 runs for up to 10 hours, with a hot-swap system allowing battery replacement in approximately 10 seconds.

Technology and AI

Shoulder sensors detect touch and enable reactive responses; a 360-degree microphone array captures speech from all directions. For fleet operations, the A3 uses UWB radio locating with centimeter-level accuracy, allowing up to 100 units to move coordinated in a shared space.

Market Significance

The Expedition A3 is quoted at a comparatively accessible price of around 110,000 US dollars and targets demonstration, service, and research applications. Within AgiBot's line of bipedal humanoids, it offers the longest stated runtime.
