Introduction of Media Network Course for Freshmen (Sep. 2025)
On Tuesday, September 30, an introductory session for first-year students was held. Students from our research laboratory also participated as representatives of the Media Network Course. We provided an overview of the course, introduced our laboratory using a poster panel, and gave demonstrations to the first-year students.
The demonstrations included:
- Real-time display of flight data using a Raspberry Pi and a software-defined radio device (aircraft position tracking)
- Real-time audio feature visualization system using an FPGA board and a Raspberry Pi
- Chapit, a voice recognition robot from Raytron
