What is the Dlr Justin?

The DLR Justin is a humanoid upper-body robot developed by the Institute of Robotics and Mechatronics at the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany. It serves primarily as a research platform for dexterous manipulation, human-robot interaction, and advanced telerobotics. Featuring two lightweight, torque-controlled arms and DLR-Hand-II four-fingered hands mounted on a 3-DOF movable torso atop an omnidirectional mobile base, Justin integrates high-fidelity force sensing in every joint. It has demonstrated landmark capabilities such as catching thrown objects, bi-manual assembly, and remote teleoperation with haptic feedback, but remains a laboratory-only system powered and computed externally.

Price & Value

New MSRP: Not for sale (research platform)

Used range: N/A

DLR Justin was never commercialized and has no retail price. As a bespoke research instrument, its value is measured in scientific output rather than capital cost. The closest commercial comparison, Willow Garage’s PR2, originally sold for $400,000, but Justin surpasses it in dexterity and force-sensing fidelity. Should a similar platform ever enter the market, a price north of $500,000 would not be surprising given the premium torque-controlled joint modules and custom hand hardware. For labs, accessing comparable technology currently requires either building a custom integration or collaborating directly with DLR.

Who Is It For?

Best for: - University robotics labs researching dexterous manipulation and whole-body control (41 DOF with full torque sensing) - Space agencies evaluating remote teleoperation for on-orbit servicing (Justin’s telerobotic demos set benchmarks) - Industrial R&D teams needing a benchmark platform for force-controlled assembly and human-robot collaboration

Not for: - Heavy industrial tasks (arm payload is only ~15 kg per arm, and the robot is tethered) - Mobile applications requiring stair climbing or outdoor operation (wheeled base, no legs) - Buyers looking for a plug-and-play commercial product (no sales channel, no warranty, requires expert system integration)

Alternatives & Comparison

In the rarified world of high-end humanoid research platforms, DLR Justin competes with a handful of comparably advanced manipulators, none of which are available off-the-shelf.

ModelPriceAvailableKey Difference
Willow Garage PR2$400,000 (original MSRP)yesMobile manipulator with open-source software, no humanoid torso; only two 7-DOF arms on a mobile base.
Kawada HRP-4UndisclosednoFull walking humanoid with 34 DOF; lighter and smaller hands, less sophisticated torque sensing.

Verdict: For research groups focused solely on bimanual manipulation and force control, DLR Justin remains the gold standard thanks to its integrated torque sensors and high-speed real-time communication. However, if mobile logistics or open-source codebase are priorities, a PR2 may be a more accessible albeit less capable alternative. The HRP-4 offers walking but significantly less hand dexterity, making it better suited for locomotion research than manipulation.

Use Cases & Capabilities

Dexterous manipulation research

Justin’s unique combination of 41 torque-controlled joints and four-fingered hands with tactile sensors allows researchers to push the boundaries of fine motor skills. It has been used to study robust grasping under uncertainty, in-hand manipulation, and even catching thrown objects in real time. The wrist force/torque sensors enable high-fidelity impedance control, making it an ideal testbed for algorithms that require precise force regulation. Because the entire system is tethered, experiments can run indefinitely without battery constraints, allowing long-duration learning sessions.

Telerobotics and teleoperation

Justin has been a flagship demonstrator for DLR’s space robotics ambitions, particularly for on-orbit servicing tasks performed from ground control. A human operator wearing an exoskeleton can control the robot’s arms and hands with haptic feedback, while head-mounted displays give stereo vision. This setup has been used to evaluate latency compensation, shared autonomy, and supervisory control schemes. The robot’s omnidirectional base and telescopic spine allow it to reach various workspaces, simulating satellite repair or assembly scenarios.

Industrial assembly and human-robot interaction

Although not deployed in factories, Justin serves as a research platform for advanced assembly concepts, including tight-tolerance peg-in-hole insertions and flexible object handling. Force-controlled joint modules allow the robot to comply naturally when interacting with humans, paving the way for safe, collaborative work cells. The dual-arm coordination algorithms developed on Justin have influenced later DLR lightweight robot arms now used in industry. However, the lack of mobility beyond a flat floor limits its direct transfer to dynamic factory floor settings.

History & Background

The DLR Justin was first assembled in 2008 by the German Aerospace Center’s Robotics and Mechatronics Institute, building on decades of lightweight robot arm research. The initial Justin featured a rigid torso and wheeled base; by 2011, the upgraded Agile Justin version incorporated a compliant, spring-loaded spine and improved hand modules, enhancing dynamic performance. Continuous incremental upgrades have kept the robot at the forefront of force-controlled manipulation, spawning spin-off technologies used in DLR’s space robot programs and industrial lightweight arms. Although never commercialized, Justin remains an active research tool and a celebrated landmark in humanoid robotics, with over a decade of demonstrated capabilities in object catching, telemanipulation, and assembly.

Buying Used — What to Check

Verify system integration Justin is not a standalone product; it relies on an external PC cluster and power supply—ensure all components are included and functional.

Assess arm/hand calibration Torque sensors and kinematic chains may drift over time; recalibration requires specialized DLR tools and expertise.

Confirm software access The robot runs a custom Linux real-time stack; without the original software framework, operation is extremely difficult.

Frequently Asked Questions

DLR Justin is not sold commercially and has no official price. It is a bespoke research platform built in-house by the German Aerospace Center. Any attempt to purchase would require a direct collaboration agreement with DLR.
Justin excels at dexterous bimanual manipulation, including catching thrown objects, precise assembly tasks, and teleoperation with haptic feedback. Its 41 torque-controlled joints and four-fingered hands allow it to handle fragile objects gently or apply precise forces, but it cannot walk—only roll on its omnidirectional base.
No. DLR Justin is strictly a research platform and has never been offered for sale. Researchers outside DLR can sometimes access the technology through joint projects or by replicating parts of its design using published papers, but there is no commercial production.
The PR2 is also a research platform but it is a mobile base with two arms and no humanoid shape; it costs about $400,000 (originally). Justin is taller, has a humanoid upper body, more advanced hands with tactile sensing, and torque control in every joint. However, PR2 has a strong open-source software ecosystem and was sold to universities, making it easier to acquire and modify.
Justin stands 190 cm tall, weighs 150 kg, and has 41 degrees of freedom: 7 per arm, 12 per hand (four-fingered), and a 3-DOF movable torso. It moves at up to 3.6 km/h on its wheeled base, lifts approximately 15 kg per arm, and is powered via an external tether.
The DLR Justin was developed by the Institute of Robotics and Mechatronics at the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany. DLR is a government-funded research organization known for space, aeronautics, and robotics research.
Justin does not have a battery. It relies on an external power supply via a tether, so runtime is unlimited as long as it is connected. This was an intentional design choice to focus on manipulation research without weight or endurance constraints.
Justin is used exclusively in academic and government research settings, particularly for advanced manipulation studies, space robotics programmes, and human-robot interaction labs. It has not been deployed in any commercial industry due to its laboratory nature.
No, Justin does not have legs. It is a wheeled humanoid that stands on an omnidirectional base, capable of moving sideways and turning. Its mobility is limited to smooth, flat indoor floors.
Justin is equipped with stereo cameras, laser scanners, torque sensors in every joint, six-axis force/torque sensors at each wrist, and tactile sensors on the fingertips. These sensors provide rich feedback for force control and environmental perception.
