Services

Everything your robot needs, under one roof.

Design, prototyping, and manufacturing services for robot startups and student teams. Bring us an idea — leave with working hardware.

Service 01

Mechanical Design & Manufacturing

From CAD model to finished parts, built to spec.

We design mechanical parts and assemblies for robots — from single brackets to full chassis — with manufacturing in mind from day one. When you approve the design, we handle prototyping and production sourcing so you get parts that actually fit and work.

  • CAD design & 3D modeling of parts and assemblies
  • DFM (design for manufacture) review to cut cost and lead time
  • Prototyping: CNC machining, 3D printing, sheet metal, laser cutting
  • Gears & transmission parts via partner factory (Nanjing Changsheng)
  • Production sourcing, quality control, and delivery

Service 02

PCB Design

Mixed-signal boards designed from the inside out.

Our team brings mixed-signal IC design experience, so we design boards with a deep understanding of what happens inside the chip and at the connector. From a napkin sketch or block diagram, we deliver production-ready schematics and layouts — and manage fabrication and assembly through our partner network.

  • Schematic design & component selection
  • Multi-layer PCB layout, including mixed-signal and high-speed sections
  • Design review focused on reliability and testability
  • Fabrication & assembly via vetted partner factories
  • Bring-up support and design iteration

Service 03

Robotics Consulting

Practical engineering guidance, fast.

Not sure where to start, or stuck partway through a build? We review your architecture, BOM, and plans, then give you honest, actionable advice — not a 40-page report. Ideal for early-stage startups validating a concept and student teams preparing for competitions.

  • System architecture & component selection review
  • BOM cost optimization without cutting corners
  • Prototype-to-production planning
  • Manufacturability review of existing designs
  • Mentoring for student and competition teams
