Blimp Altitude Filtering Algorithm (Second Order)

Ethan Uetrecht

This past week, I focused on improving upon the altitude filtering algorithms I had tested previously for the blimps on FORAY. The previous two algorithms I had implemented (both in arduino and in MATLAB) were a moving average filter and an exponential filter (both first-order filters). Both intro...

FORAY - multiple peripheral devices connected to the same laptop

Parth Agrawal

In case, we have a limited number of laptops to connect the game controllers and master devices. This experiment shows that multiple game controllers can be connected to the same laptop for communication. The current communication system is limited by the number of ports. We can overcome this limita...
