Empowering the Next Generation of Robotics

Our Focus

Apptronik offers robotic engineering services as well products that are a result of our innovations. Now anybody from hobbyists to advanced researchers have the opportunity to use the same components used in leading robotic programs.
Go to Design and Integration Services

Design and Integration Services

We have extensive experience in designing and fabricating human-centered robotics to help you on your project.

Go to Series Elastic Actuators

Series Elastic Actuators

Apptronik electric actuators have the power density, compliance and control of hydraulic actuators while maintaining much higher efficiency. This makes them ideal in any application where precision and power in a small package are a requirement.

Go to Real-time control systems

Real-time control systems

We offer an open-access high-performance embedded system control solution built on Ether-CAT communications, high-end micro-controllers, and a modular hardware design to offer a complete, versatile, and compact foundation for your robotics and automation needs.

Go to Research and Education Tools

Research and Education Tools

The Taurus Test System is the perfect tool to develop and validate control software and Apptronik actuators before implementing them into larger systems. Taurus is also a valuable educational tool where students and teachers can learn about control techniques on a real system versus the traditional method of computer simulation.

The Apptronik Approach

Human-Centered Robot Design, Cutting Edge Components

Apptronik is developing robots that can live and work with humans to make our lives safer, more productive and easier. Our expertise comes from our mechatronic and control software contributions for advanced legged robots including NASA’s Valkyrie humanoid robot and Meka’s Hume point foot biped. Our research and development is leading to new innovations that are making robots lighter, safer and more powerful than ever before. As we develop these innovations we are making them available to everybody for use in their own research and projects.
