Open-ended Remote Controlled Airsoft System (ORCAS)

Project features: The ORCAS project implements a wirelessly controlled gel blaster turret that can be controlled via the web browser on a mobile phone. The turret equips a gel blaster modified from Jinming Gen8 gel blaster gearbox and a laser head for zeroing. The turret fires 7-8mm gel balls, and its barrel assembly contains an LED board as a tracer, but it fails to light up the glowing gel balls as expected. The turret equips a LED board to provide illumination of the forward aiming view. The turret equips a infrared laser ranging sensor to measure the distance to the aimed target. The turret equips an ultrasonic rangefinder that acts as a radar to measure the distance between it and surrounding objects. Two NEMA 17 stepper motors driven by A4988 modules are used to implement the pan/tilt rotation of the turret. Two 15BY micro stepper motors driven by A4988 modules are used to implement gel balls feeding and the radar rotation. The above electronic components are integrated and controlled by the STM32F103 MCU, which implement driver commands through the UART interface for integration with the upper-level MCUs or computer. The turret equips a Raspberry Pi camera module to provide a first-person view to navigate the turning of the turret. The turret equips a Raspberry Pi Zero 2 W board to run a static web server that provides a user interface for connected clients to stream images captured by the camera to the client and transmit control requests from the client to the MCU. The turret is powered by a 12V power supply and an extra airsoft battery.
