History and Development
Origins of the AH Series
The AH series traces its lineage to ARC’s original Humanoid Research Platform (HRP), which entered development in the early 2010s. The HRP focused on basic locomotion and object manipulation, providing a foundation for subsequent models. By 2017, ARC announced the AH1, a prototype aimed at assisting in eldercare. The AH1's limited field testing highlighted the need for enhanced sensory perception and natural language processing, prompting the creation of a more sophisticated iteration that would evolve into the AH12.
Development of the AH12
The AH12 development cycle spanned three years, from 2019 to 2022. Key milestones included the integration of a stereoscopic vision system, a pressure‑sensing glove interface, and a cloud‑connected learning module. In 2023, ARC performed its first series of controlled environment trials, evaluating mobility on uneven terrain and compliance with medical safety standards. The final design was finalized in late 2023, with production slated to begin in early 2024.

The anthropomorphic form features a height of 1.70 meters, an arm span of 1.80 meters, and articulated joints at the shoulders, elbows, wrists, hips, knees, and ankles. Silicone‑based skin panels cover the torso and extremities, allowing for realistic tactile feedback and temperature regulation.
Sensor Suite
Central to the AH12’s capabilities is a comprehensive sensor array. The robot is equipped with dual RGB‑D cameras, a panoramic LiDAR system, and an array of ultrasonic distance sensors distributed across the limbs. An array of touch sensors embedded in the palms and fingertips measures pressure with a resolution of 0.01 newtons. The head contains a 3‑axis inertial measurement unit (IMU) and microphones arranged in a tetrahedral configuration for binaural audio capture.
Actuation and Control Systems
The actuators are direct‑drive servo motors with a torque range of 0.5 to 10 newton‑meters, allowing for precise force control. The AH12 employs a hierarchical control architecture: a low‑level controller manages joint torque and balance, while a mid‑level behavior planner interprets sensor data into task‑specific motions. The top‑level controller handles high‑level decision making and natural language comprehension. All control loops operate at 250 Hz, ensuring smooth and responsive operation.
