EMYS Is Watching You: ProJet® HD 3000 Speeds Up Robotic Project

“It has been a great experience, turning ideas into real parts and allowing us to test concepts in just a few hours. The quality is unsurpassed.” - Prof Krzysztof Tchon

LIREC is a European funded research project that explores how we live with digital and interactive companions.

As one of 9 partners in LIREC, the Department of Fundamental Cybernetics and Robotics at Wroclaw University of Technology in Poland develops EMYS, the robotic head project initiated by Professor Krzysztof Tchon and his team of eight specialists. EMYS’ purpose is to examine functionality of the construction in the scope of human-robot interaction. In this specific project the task was to implement a turtle shape head which is able to generate facial expressions.

The novelty of the design, made it impossible to use off-the-shelf solutions. Both  the head hardware and software had to be made from scratch. Finding that using traditional milling or tooling methods to produce the shape of EMYS was too time consuming and costly, the project team began looking for ways to accelerate the effort. In their search, which included making the production process more costeffective, they found the right partner, Cad-Mech, a construction service office and Polish reseller of 3D Systems personal and professional 3D printers.

When preliminary testing proved that the ProJet parts fulfilled the project requirements, every single EMYS cover element, from the head cover to functional parts like the moving eyelids and the connectors linking the eyes to the servomotors, were produced using the ProJet HD 3000 3D printer (now sold as the ProJet 3510) in a matter of hours. The printed functional parts were assembled with the other mechanical parts and electronic components. Finally the smooth, outer parts of the head, painted for aesthetics, were put into place. Colleagues from the other European Universities followed the birth of EMYS and were really interested in the ProJet Professional Printer which turned the head project into reality very rapidly. After the first head went “live”, two additional heads were produced, assembled and sent to the LIREC partners in Portugal and the UK.
