Mechatronics

 

Service RoboticsMechatronics is the convergence of mechanical, electrical and control engineering to give advanced functionality to products and systems.

Robotae’s multi-disciplinary expertise includes developing control algorithms that are needed at the interface between hardware and software, and designing hardware to be suitable for such levels of control.

Supporting development of an industrial demonstrator

Robotae provided electrical and control engineering services to Archipelago Technology, assisting in the development of an advanced industrial demonstrator of their PowerDrop viscous liquid printing technology for a multi-national client.

These services have included:

  • Design, build and commissioning of an electrical control cabinet, housing an Allen Bradley PLC, three-phase servo drives, safety circuit (including several interlocks), solid state relays, mains filters and circuit protection components.
  • PLC software development
  • Motor sizing calculations, determining which motors and reductions ratios to use
  • Servo tuning
  • Mechanical design of a ‘shuttle’—a linear axis that simulates a substrate passing under the print head on a production line. The shuttle accelerates to 4 m/s during the first 50 cm of travel, continues at constant speed under the print head, then comes to a stop in the last 50 cm, using a jerk-limited motion profile at accelerations up to 20 m/s2, all synchronised with the rotation of the PowerDrop print drum.
  • Specification and commissioning of a Festo fieldbus module providing pneumatic valves, pressure sensing, thermocouple and PT100 inputs, and digital I/O.
  • Design and implementation of a touchscreen HMI
  • Continued support and advice on an ad-hoc basis, enabling experiments and modifications to Archipelago’s process as needed

Archipelago’s CEO, Dr Guy Newcombe, comments “Kevin has provided an excellent all round service. He has worked well with both the Archipelago team and our client. I have no hesitation in recommending Robotae.”

Change of Paradigm


Housed in a specially built darkroom, the gonioreflectometer takes images of a textile sample (in the centre) from different angles using a camera on one arm, illuminated from many directions by a high quality spotlight on the other arm, to measure and characterise its reflective properties.

Change of Paradigm is moving fashion towards a digital revolution, providing luxury fashion at an affordable price by selling exclusively from photorealistic 3D-simulated garments before they’re produced, thereby eliminating over-production.

Robotae has designed a gonioreflectometer to take images of textile samples from different angles, illuminated from many directions to measure and characterise their reflective properties. These visual properties will enable game-changing photorealistic rendering of high end fashion, as the eventual 3D rendered images will display accurate texture and movement of the materials.

Robotae designed and built the device, including construction of a purpose-built darkroom to house the system.
