The low-cost robotic arm HELENE, developed in the measurement and sensor technology group, has been in use in research and teaching for several years. The development began in 2019 due to the need for an affordable and customizable solution that would not compromise on functionality. Learn more

Apart from a few standard components, the robot can be entirely build using a common 3D printer, as is now widely used in various fields. The total cost is under 1000€, enabling its use in education, where real hardware was previously seldom available. As part of the measurement technology lab in the 4th semester, several of these robots are available to perform liver biopsies on tissue phantoms. This course was awarded the Faculty Prize for Excellence in Teaching (Athene Prize). Learn more

The use of real hardware has paid off: A study demonstrated that students are able to work with a KUKA industrial robot more quickly after this course. The results were presented at the EDUCON conference in London this year. Learn more

In addition, HELENE is reliably used in various research applications, especially benefiting from its simple adaptability. All components from the mechanics to the modular electronics and software can be tailored to individual needs. In the context of a project seminar, the robot's characteristics were also determined. The design, properties, and applications were recently published in the Hardware Journal. Learn moreAll data for replication and an assembly guide are freely available online.
