YuChung Lin developed the Open-ended Remote Controlled Airsoft System (ORCAS), a wireless gel blaster turret controlled through a mobile phone's web browser. The turret's core firing mechanism uses a modified Jinming Gen8 gel blaster gearbox, which shoots 7-8mm gel balls. It's equipped with various sensors and viewing components to aid in its operation. A Raspberry Pi camera module provides a first-person view for navigation, while a separate LED board illuminates the forward view.
