About the book →An open-platform, fully programmable miniature humanoid with 20 metal-geared DYNAMIXEL joints and an onboard PC, built for hands-on robotics research and advanced STEM education.
The Robotis DARwIn-OP2 (officially branded ROBOTIS OP2) is a compact, bipedal humanoid robot designed as an open hardware and software platform for university labs, research teams, and advanced robotics programs. It walks, balances, gets up off the ground, sees through an onboard camera, and runs your own code -- making it one of the most accessible full-humanoid research platforms on the market. RobotLAB supplies the DARwIn-OP2 to North American institutions with the procurement support, deployment guidance, and training that academic and lab buyers need.
Under the hood, the OP2 carries a built-in PC (Intel Atom N2600 dual-core, 4GB RAM, 32GB mSATA) plus a dedicated CM-740 sub-controller for real-time joint and sensor management. Twenty DYNAMIXEL MX-28T actuators with durable metallic gears drive 6 degrees of freedom in each leg, 3 in each arm, and 2 in the neck, giving the robot dynamic walking, kicking, and recovery motions. Because both the hardware design and the control software are open, every layer -- gait, vision, kinematics, behavior -- is yours to modify, which is why the DARwIn family became a fixture of the RoboCup Humanoid soccer league.
As a reseller, RobotLAB positions the DARwIn-OP2 for buyers who want a proven, code-it-yourself humanoid rather than a closed consumer robot. It runs standard 32-bit Linux or Windows, ships with reference walking and vision software, and connects over Gigabit Ethernet or Wi-Fi. The RobotLAB price is $9,600. RobotLAB can advise on whether the OP2 or its successor, the DARWIN OP3, better fits your curriculum, research roadmap, and budget.

The OP2 is a workhorse for academic labs studying bipedal locomotion, gait generation, inverse kinematics, computer vision, and human-robot interaction. Its open architecture lets graduate students and faculty replace any part of the control stack and run experiments on real hardware instead of simulation alone. The onboard Intel Atom PC means perception and control can run on the robot itself.
Engineering and computer science departments use the DARwIn-OP2 to teach robotics, embedded systems, and AI with a tangible full-humanoid platform. Because it programs in standard Linux/Windows environments with open-source reference code, it bridges classroom theory and physical experimentation for upper-level undergraduate and graduate students.
The DARwIn lineage is closely tied to the RoboCup Humanoid KidSize soccer league, where DARwIn-OP robots won multiple championships. Student and research teams adopt the OP2 to develop walking, ball-tracking, and autonomous behavior code for competition, benefiting from a large existing community and shared codebase.
Its small size, expressive motions, and ability to stand up after a fall make the OP2 an engaging demo robot for open houses, recruiting events, and public science outreach -- showcasing real humanoid capability without the footprint or cost of a full-size service robot.
Same-day response. We handle delivery, on-site setup, staff training, and ongoing service nationwide.
It is best suited for humanoid robotics research and advanced STEM education -- studying bipedal walking, vision, AI, and human-robot interaction on a real, fully programmable robot. It is also a popular RoboCup soccer platform. For help matching it to your research or curriculum, call 1-87-RobotLAB.
Yes. Both the hardware design and the control software are open, so researchers and students can modify the gait, vision, kinematics, and behavior code. It runs on standard 32-bit Linux or Windows with open-source reference software. Call 1-87-RobotLAB if you need guidance on the development environment.
Both share the same 20-DOF DYNAMIXEL MX-28T layout, but the OP3 upgrades the onboard computer to an Intel NUC (Core i3, 64-bit) versus the OP2's Intel Atom dual-core PC, and adds newer connectivity. The OP3 lists at $11,000 versus $9,600 for the OP2. Call 1-87-RobotLAB to decide which fits your needs and budget.
The OP2 has a built-in PC -- Intel Atom N2600 dual-core, 4GB RAM, 32GB mSATA -- running 32-bit Linux or Windows, plus a CM-740 ARM Cortex-M3 sub-controller for real-time joint and sensor handling. You program it in standard development environments. Call 1-87-RobotLAB for onboarding support.
The included 1800mAh LiPo battery provides roughly 30 minutes of operation. It ships with a charger and an external power adapter, so you can run the robot tethered for extended lab sessions. For battery and accessory questions, call 1-87-RobotLAB.
RobotLAB is a full-service reseller and can sell the DARwIn-OP2 outright at $9,600, and discuss leasing, RaaS subscription, deployment, and training options for institutions. Call 1-87-RobotLAB to review the right purchasing path for your organization.
We list exact height and weight as Contact for details to avoid quoting unverified figures, though the OP2 is a small tabletop-scale humanoid in the same size class as the DARWIN OP3. Call 1-87-RobotLAB for the confirmed mechanical specifications.
