NEW CHALLENGES FOR 2014

Robotic Arm Remote control

-Design and assembly of a robotic arm

- Remote control of the Machine and the robotic arm

Hardware Engineering

Software Engineering

The HW students will learn new concepts, develop the Electronic schematics and the PCB layouts, will choose the right components and assemble the boards

The SW students will learn programming techniques, develop new software modules for the existing and/or the new hw infrastructure and integrate them with the already existing part.

The Project will be developed respecting the development phases that we have for CES Products and the students will have the chance to work in an interdisciplinary team. Team work will be a key for achieving the objectives.
