AGILOped: Agile Open-Source Humanoid Robot for Research

2025-09-11

AI Summary

Contemporary high-performance humanoid robots are typically closed-source, expensive, and complex to deploy—severely hindering academic research and application exploration. To address these limitations, we present an open-source, lightweight, and low-cost high-performance humanoid robot system. Its fully open-hardware stack integrates commercially available high-power-density reversible actuators and standardized electronic components. The robot stands 110 cm tall, weighs 14.5 kg, and supports single-person deployment without hoisting equipment. It achieves robust dynamic locomotion—including stable bipedal walking, jumping, impact resilience, and autonomous self-righting. Crucially, this design delivers exceptional motion performance while dramatically lowering development and maintenance barriers. To our knowledge, it is the first open-source humanoid platform to simultaneously achieve high performance, light weight, and operational simplicity. The system provides a reproducible, extensible experimental platform for embodied intelligence research.

Abstract

With academic and commercial interest for humanoid robots peaking, multiple platforms are being developed. Through a high level of customization, they showcase impressive performance. Most of these systems remain closed-source or have high acquisition and maintenance costs, however. In this work, we present AGILOped - an open-source humanoid robot that closes the gap between high performance and accessibility. Our robot is driven by off-the-shelf backdrivable actuators with high power density and uses standard electronic components. With a height of 110 cm and weighing only 14.5 kg, AGILOped can be operated without a gantry by a single person. Experiments in walking, jumping, impact mitigation and getting-up demonstrate its viability for use in research.
