AC LABS 2014
NEW CHALLENGES FOR 2014
Hardware 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

Software Engineering
Robotic Arm
-Design and assembly of a
robotic arm

Remote
control
- Remote control of
the Machine and the
robotic arm

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.
