AgiBot X2-N (AgiBot) vs ALICE 4 (AEI Robot)

AgiBot X2-N features typical humanoid proportions with a height of 175 cm and an estimated width and length approximating human dimensions, weighing 55 kg. It integrates a hybrid locomotion design that enables walking and rolling for mobility efficiency. ALICE 4 is more compact at 160 x 50 x 30 cm and lighter at 45 kg, emphasizing a more slender and possibly more maneuverable form factor optimized for indoor use.

The AgiBot X2-N achieves a higher speed of 7 km/h through its hybrid locomotion system, relying on proprioceptive feedback without external sensors like GPS or LiDAR. It excels in dynamic, unstructured terrains, adapting gait in real time. ALICE 4 moves slower at 0.8 m/s (~2.88 km/h) but compensates with rich sensor input enabling indoor SLAM via visual and LiDAR mapping, supporting precise navigation in controlled indoor environments.

AgiBot X2-N utilizes proprioceptive sensors including joint torque, pressure, and internal gyroscopes exclusively, foregoing cameras or external sensors to maintain robustness in complex settings. In contrast, ALICE 4 is equipped with multiple sensing modalities such as RGB and stereo cameras, depth sensors, LiDAR, ultrasonic sensors, IMU, gyroscope, force, and temperature sensors, providing comprehensive environmental perception and situational awareness.

AgiBot X2-N operates on an autonomous AI system integrated with Linux/ROS, featuring real-time control and gait adjustments without dependency on visual input. Its reliance on proprioceptive data suggests a strong focus on motion intelligence. ALICE 4 supports teleoperation, autonomous functions, and learned behaviors, utilizing ROS2 and proprietary software with APIs in Python and C++, enabling flexible programming and control paradigms for various applications.

AgiBot X2-N offers a notably long battery life ranging from 3 to 5 years and supports charging within 2-4 hours, indicating a high-capacity battery system suitable for extended deployments. ALICE 4's battery life is approximately 3 years, reflecting typical operational endurance for indoor humanoid robots, and is designed for moderate power consumption in service applications.

AgiBot X2-N is suited for logistics, search-and-rescue, industrial automation, and navigation in dynamic environments, leveraging its autonomous mobility and proprioceptive sensing. ALICE 4 targets pick-and-place workflows, research, VR teleoperation, and collaborative service applications, emphasizing indoor operation, precise navigation, and interaction through its rich multisensory setup and control versatility.

Both robots incorporate essential safety measures such as emergency stop functions. AgiBot X2-N additionally employs obstacle avoidance through proprioceptive feedback and real-time gait adjustments to maintain stability. ALICE 4 features force limiting, collision detection, and a collaborative mode designed for safe human-robot interaction in shared environments.

AgiBot X2-N runs on a Linux/ROS-based platform emphasizing open systems for control and real-time adjustments. ALICE 4 uses ROS2 alongside proprietary software with APIs supporting Python and C++, offering a robust development environment tailored for research and applications requiring varied programming approaches.

The estimated price range for AgiBot X2-N is USD $50,000–$150,000, reflecting its advanced hybrid mobility and autonomy. ALICE 4 is priced between $50,000 and $100,000, aligning with its sensor-rich configuration and indoor application focus. The wider price range of AgiBot X2-N suggests more customizable or scalable configurations.
