Boston Dynamics Atlas (Hydraulic) — Specs, Price & Where to Buy (2026)

The hydraulic Atlas was never sold commercially. It was a proprietary research platform built by Boston Dynamics. The estimated per‑unit cost exceeded $1 million, but no list price ever existed.

Atlas could walk, jog, climb obstacles, perform backflips, and execute dynamic parkour routines. It carried up to 11 kg payloads and was designed for DARPA disaster‑response tasks like driving a vehicle and opening doors. However, its runtime was limited to about 1 hour on battery.

No. The hydraulic Atlas was discontinued in April 2024 and was never sold to the public. It was an internal Boston Dynamics research platform and is now succeeded by an all‑electric Atlas.

The hydraulic Atlas relied on high‑pressure fluid actuation, enabling explosive moves like backflips but with loud noise and 1‑hour battery life. The electric Atlas (2024) uses all‑electric motors for quiet, efficient operation and a 360° joint range, sacrificing pure explosive power for practicality and longer runtime. The electric version is still in development and not yet commercially available.

Height: 1.88 m (6 ft 2 in). Weight: 150 kg (330 lbs). 28 degrees of freedom. Battery life: 1 hour. Max speed: 5.4 km/h (1.5 m/s). Payload: 11 kg. Sensors included stereo cameras, LIDAR, and IMU.

Boston Dynamics, founded in 1992 in Waltham, Massachusetts, USA. The company is now a subsidiary of Hyundai Motor Group and is known for dynamic legged robots like Spot and BigDog.

The onboard 3.7 kWh lithium‑ion battery provided approximately 1 hour of operation, depending on activity. Charging time was not publicly disclosed, and the battery was not swappable in the field.

No industries used it operationally. It was strictly a research and development platform for academic and DARPA teams, informing future humanoid designs for manufacturing, logistics, and disaster response.

Boston Dynamics retired the hydraulic Atlas in 2024 to focus on a quieter, more practical all‑electric design. The hydraulic system’s noise, maintenance needs, and limited battery life made it unsuitable for commercial applications.
