Experience

EtherCAT Motion Controller

A motion controller for high precision motion control systems. The controller can behave as an EtherCAT master, making it possible to achieve very precise synchronization of multiple motor drives. It can also flexibly communicate with multiple sensors and actuators on the same EtherCAT segment. I implemented it in C and C++ on the hardware of my own design.

I also implemented libraries for Python and C to communicate with the controller through a PC, thus making it easier to send commands and receive acquired data.

Revamping a Fire-control System

I implemented a gun motion control on a dedicated processor for azimuth and elevation positioning. I also implemented ballistics calculations on an industrial PC running QNX. The operator console was implemented on a PC running Windows. All components were interconnected via an Ethernet network.

Electronic and Software Development for Testing Machines

I designed and implemented a motion control system and data acquisition on dedicated controllers for testing machines. I was also tasked with software development for human machine interface, test configuration, and data processing.

Machine Cycle Time Tracking

I was the software developer of an acquisition system to track the cycle time of each machine on a shock absorber production line. Based on this information, the system could detect where the bottleneck was and if any machine wasn't working correctly or stopped. With that information, it was possible to speed up the entire cycle time of the production line.
