Of data, even though there are only four flight commands - roll (strafe left/right), elevation (forward/backward), throttle (up/down), and azimuth (turn). Furthermore, the system is set up to send six channels Luckily, though, Tim’s handheld radio controller sends a 3.3V PWM signal at 50 Hz. The signal to change the state of the relays needed to come from the Raspberry Pi itself, since the handheld radio controller cannot send digital signals that the relay will Rather than actually calculate and control the dynamics of the quadcopter. This also allows the Raspberry Pi to only need to send desired directions - such as “fly forward”. It is possible to change where control signals are coming from. This happens mechanically by moving a solenoid against a spring.īy connecting the signal from the handheld radio controller to the “normally closed” contact, and the signal from the Raspberry Pi to the “normally open” contact, Once energized, the switch flips, and a “normally open” contact makes a connection with the “common” contact. When not energized, the a “normally closed” contact is connected to the “common” contact. A relay is a switch controlled by a logic signal. Therefore, a multi-channel relay was used.

Therefore, the team made the first goal of development ensuring it was possible to regain control should the quadcopter begin to fly away. Although the quadcopter is small, the speed of the blades creates a safety hazard.įurthermore, a “runaway” quadcopter scenario can be dangerous for airplanes in the surrounding area, and is also illegal. For offensive purposes, the QuadCopter is armed with various missile pods built into the hull of the craft as well as a GAU-17/A Gatling Gun mounted on the underside of the cockpit.It is very risky to allow an aircraft to behave autonomously. To secure its targets, the craft will hover over the area and deploy an Extraction Claw, which retrieves and returns the victim to the QuadCopter. It possesses four large rotors, one on each wing, for propulsion and takeoff/landing. The HYDRA QuadCopter is an advanced quadrotor VTOL aircraft designed for the quick capture and transport of Inhumans. Years later, Ruby Hale and Werner von Strucker used a HYDRA QuadCopter to journey to a facility in England where the Particle Infusion Chamber was kept by HYDRA. They released the Absolution Virus inside the Playground form the QuadCopter, and then landed in the base's hangar, where they rejoined with Hive. After he was caught by S.H.I.E.L.D., Hive's servants, Giyera and Hellfire, used the QuadCopter to reach his location in the Playground. With the fall of HYDRA, Hive possessed many of HYDRA equipment, including the QuadCopter. The QuadCopter deployed its Extraction Claw, captured Hinton, and flew off to Gideon Malick. The craft focused its attention to Charles Hinton, the target Inhuman. The QuadCopter fired its missiles as a distraction and destroyed several police cars before killing Abbott with its minigun. Upon arriving in Dyker Heights, New York City, the craft was spotted and fired upon by S.H.I.E.L.D.

Believing this to be an Inhuman occurrence, HYDRA sent a HYDRA QuadCopter to investigate. While monitoring emergency response lines, HYDRA was alerted to Edwin Abbott, a man who claimed to have a vision in which he would be killed by HYDRA. The craft captured Lucio in its cargo bay and returned to Gideon Malick's Headquarters. The rotorcraft arrived at a station of the National Police of Colombia and deployed an Extraction Claw, using it to drill through the roof. After receiving reports of Inhuman activity in Bogotá, Colombia, a QuadCopter was dispatched to retrieve the powered persons. In response to Gideon Malick's desire to build an Inhuman army for Hive, HYDRA developed the QuadCopter as a tool for capturing Inhumans.
