Scope · detail A

Robotics and product development

Robotics: mechanism design, actuation, end effectors and sensor integration. I understand the requirements and know how to integrate software and electronics alongside the mechanical design of a robot's different parts, balancing weight, cost and complexity.

Product development: the mechanical design is mine, then I carry it through analysis, DFM, vendor selection and commissioning. I have carried both disciplines on the same programme.

Hong Kong, GMT+8

A robotMechanism, end effector, actuation and controls integration, from requirements or from an existing design. A productPrototype through to production: analysis, DFM, tooling, vendor selection and commissioning. A rigTest benches, fixtures and one-off equipment built to produce data a programme needs. A roleFull time or contract within a hardware team. Hong Kong or remote. AdvisoryDesign reviews, feasibility assessments and independent second opinions.

Sect. A · span of practice

I have led a product from one end to the other

The stages below run in the order the work happens: the requirement that starts a programme through to hardware installed and running. I have carried a product across that whole distance, and led the work at each stage on programmes that shipped: surgical robotics, orthopaedic implants, ocean robotics and a 15,000 A industrial plant. Each stage carries its own evidence.

RequirementDepth at each stage, carried end to end, one engineerCommissioned

01Requirements and conceptI talk to the people who will use the thing, then agree what has to be true before anything gets modelled.A wrist-driven orthosis specified with people living with spinal cord injury.

02Mechanism designLinkages, travel, load paths, safety. The part where the machine gets decided.Motion and safety mechanisms for a surgical robotic system at Precision Robotics.

03CAD and drawingsModelled properly and drawn properly. A shop can quote from what I send without asking me a question.Subsystem drawings released straight to CNC and vacuum cast production.

04Analysis and simulationNumbers before metal. Strength, stiffness, heat, life.Implant strength compared across designs at Lifespans. Every conductor and joint sized at 15,000 A.

05Materials and processPicked for the duty and for the process that has to make it, not for the datasheet.Eight material families specified across one plant at Sparkmate.

06Tolerancing and GD&TFits, stack-ups, datums. Where a design either assembles or does not.Production release with Mainland vendors at Precision Robotics.

07Electromechanical and controlsI write the code that makes the hardware move and reads what it did, and I design the power that feeds it.15,000 A power distribution and high current PLC cabinets. Python automation, eight times faster data processing.

08PrototypingBuild it, break it, measure it, change it.The first water-going ClearBot prototype, built out of a dorm room.

09Testing and validationA design is not finished until something has tried to break it, and the model gets corrected by what the test said.Implants tested to failure at Lifespans. Test rigs at Precision Robotics. A robot tested in open water. The surgical system progressed to cadaveric and animal trials.

10DFM and DFARedraw the part so the process can make it, at the volume and the price it has to hit.Concept through DFM to CNC and vacuum cast production at Precision Robotics.

11Sourcing and productionI place the fabrication directly with the shops. No agent, and you do not have to fly there.Owned manufacturing across vendors, processes and materials at Sparkmate.

12Install and commissioningFabrication supervised, hardware installed, system handed over working.A 15,000 A electrolysis plant, commissioned and running.

General notes

01Open to: a casual project as much as a full-time role, picking up a problem partway through as much as starting one from scratch. Hong Kong permanent resident, based here or open to remote.

02Whether the role is called mechanical engineer, robotics engineer or product development engineer, the work is the same: surgical robot mechanisms at Precision Robotics, orthopaedic implants at Lifespans, a 15,000 A plant at Sparkmate and ocean robots at ClearBot. Hong Kong, Shenzhen or remote.
