*TECHNOLOGY TUESDAY* 

Today we would like to use our Technology Tuesday to tell you more about some electrical components the Electrical Department designed and that were made in collaboration with our partner Global Electronics. Global Electronics is a company that is very socially involved, which is one of the reasons for them to become our partner. Another reason is their close collaboration with the Delft University of Technology in general. They are also a company that is supporting a new generation of engineers, for example by means of advice with regard to the manufacturability of electronical components used in high-tech projects. Furthermore, all their products are made in Holland, which characterizes Global Electronics. In the video below you see a nice overview of their complete production process.

Global Electronics is a valuable sponsor for Project MARCH, supporting the Electrical department in design and assembly of our main electrical components. The first of them is the PDB (shown in the first image), or Power Distribution Board, which manages power distribution in a smart way to ensure safe usage of the MARCH II. It can closely monitor information such as battery charge, power consumption and temperature. It also includes a booting system that we call Layered Booting, which makes sure that all control electronics are fully operational before enabling any motors to turn. This, along with an emergency stop, ensures that Ruben can safely operate the MARCH II.

The second device that Global Electronics has manufactured for Project MARCH is the GES (shown in the second image), or General EtherCAT Slave, which is a versatile system that can receive and process sensor data before sending it to the central computer of the exoskeleton. It processes data such as motor temperature, exoskeleton positioning (using an IMU) and pilot input. The GES is used in multiple locations of the MARCH II, including the legs and back of the exoskeleton.

We would like to thank Global Electronics in this way for all their support this year!
