OUR MISSION

We deploy decades of expertise delivering custom mechanisms in accelerated timeframes, focusing on system-level efficiencies and design precision.

APPROACH

What We Do

Custom space mechanisms

that meet the needs of a specific spacecraft.

Incorporates state-of-art component technologies

Early adopters of now-standard
space drivetrain components and manufacturing processes.

Space-qualify core building blocks

Drivetrains, seals, and joints – and form them into custom systems (ex: robotic arms, multi-DOF gimbals, pressure control valves).

We meet tight procurement schedules, and highly value quality project management and open communication and with our commercial & government customers.AI And Robotics

In-house production & assembly

Efficiency → accuracy → lifetime

Design

  • High accuracy & resolution drivetrain
  • Dual encoders control system
  • Minimum number of parts
  • Survives launch loads
  • Survives space: low friction, thermal dissipation
  • As-needed built-in electronics
  • MTBF and qual test results provided at CDR

PRIOR WORK
& CLOSE ASSOCIATES

Passed numerous test requirements (vibe/acoustic qualification on a Falcon Heavy, DO-160, etc.)

Successful delivery in regulated & ruggedized industries: space, defense, industrial, medical.

Maintains close relationships with key space component suppliers.

CTO’s prior Intellectual Property is the basis for leading space motor component providers.
