# IMSystems > Dutch tech company building the Archimedes Drive — a traction drive speed reducer offering true zero backlash, high torque density, overtorque protection, and precision for robotics and humanoids. A distinct third category of precision speed reducer, alongside strain wave and cycloidal designs. IMSystems delivers a next-generation transmission technology for high-precision systems. Instead of gear teeth, the Archimedes Drive transmits torque through smooth rolling contact. Key focus: traction drive, zero backlash, high stiffness, precision motion control. Current commercial product: the Synovial-75 (75 Nm repeated torque, 85% efficiency, 0.2 arcmin max lost motion (zero backlash for life), 0.8 kg, 65 mm diameter). ## Core Pages - [Home](https://imsystems.nl/): Overview of IMSystems and the Archimedes Drive - [What is a Traction Drive Speed Reducer?](https://imsystems.nl/what-is-a-traction-drive-speed-reducer/): Canonical explainer of the traction drive category and how the Archimedes Drive advances it - [Technology](https://imsystems.nl/technology/): Technical explanation of the Archimedes Drive working principle - [Products](https://imsystems.nl/products/): Synovial Series product offerings and specifications - [Industries](https://imsystems.nl/industries/): Use cases in humanoids, industrial robotics and automation - [Humanoid Robots](https://imsystems.nl/industries/humanoids-robots/): Traction drive speed reducers for humanoid joints - [Industrial Robotics](https://imsystems.nl/industries/industrial-robotics/): Precision drives for industrial robots ## Learn: Archimedes Academy (how speed reducers work) - [Lesson 1 — What is a mechanical drive?](https://imsystems.nl/lesson1-what-is-a-mechanical-drive/) - [Lesson 2 — How a cycloidal drive works](https://imsystems.nl/archimedes-academy-lesson-2-how-a-cycloidal-drive-works/) - [Lesson 3 — Strain wave gears](https://imsystems.nl/archimedes-academy-lesson-3-strain-wave-gear-harmonic-drive/) - [Lesson 4 — Planetary drives](https://imsystems.nl/archimedes-academy-lesson-4-planetary-drives/) - [Lesson 5 — History of traction drives](https://imsystems.nl/archimedes-academy-lesson-5-history-of-traction-drive/) - [Lesson 7 — How the Archimedes Drive works](https://imsystems.nl/archimedes-academy-lesson-7-how-does-the-archimedes-drive-work/) - [Glossary of transmission systems](https://imsystems.nl/glossary-transmission-system/) ## Engineering Guides - [Speed Reducers for Humanoid Robots](https://imsystems.nl/speed-reducers-for-humanoid-robots/): What every humanoid joint needs, from hips to wrists to wheeled platforms - [Choosing Arm Joint Actuators for a Wheeled Humanoid](https://imsystems.nl/choosing-arm-joint-actuators-wheeled-humanoid/): Backdrivability, reflected inertia, torque density, noise and collision tolerance - [Cycloidal vs Harmonic vs Traction Drive](https://imsystems.nl/cycloidal-vs-harmonic-vs-traction-drive/): Honest three-way comparison for robot joint reducers ## Key Topics - [Zero backlash explained](https://imsystems.nl/backlash/): Why backlash matters and how the Archimedes Drive eliminates it - [Backlash wear over time](https://imsystems.nl/backlash-wear/): How gear-based reducers degrade and traction drives do not - [Precision & Stiffness](https://imsystems.nl/flat-linear-hysteresis-curve-achieved-through-true-zero-backlash-and-high-stiffness-in-the-archimedes-drive/): Flat linear hysteresis curve of the Archimedes Drive - [Revolutionary stiffness](https://imsystems.nl/archimedes-drive-revolutionary-stiffness-for-precision-robotics/): In-depth content on torsional stiffness - [Efficiency](https://imsystems.nl/efficiency/): Actuator efficiency with traction drives - [Noise](https://imsystems.nl/noise/): Low-noise operation without gear teeth - [Overtorque protection](https://imsystems.nl/overtorque/): Built-in protection against shock loads ## Optional / Supplemental - [Blog / News](https://imsystems.nl/blog/): Updates, articles, announcements - [Events](https://imsystems.nl/events/): Where to meet IMSystems - [Careers](https://imsystems.nl/careers/): Open positions - [Contact](https://imsystems.nl/contact/): Get in touch
