We build robots, the actuators that move them, and open tools for the people who make them. Designed in the open, shared with the community.
open the harmonic maker →<robotics/>
Machines that move with purpose, from desktop arms to mobile platforms, engineered to be built, fixed, and understood.
<actuators/>
Compact harmonic drive actuators you can print and assemble yourself. High reduction, zero backlash, no gatekeeping. Start with the HD20: 20:1, NEMA 17, about $4 of hardware.
<open-tools/>
Free design tools for the community, starting with our harmonic drive tooth generator, with parametric profiles, exported as DXF.
