#TITLE OF THE PROJECT:
Electromagnetic Launch System with Switchblade Drone

# PROBLEM:
The Switchblade UAVs in use today tend to use pneumatics for power. It has been limited by its launching speed, cost, and portability. Making use of electromagnetic technology can improve the design. The project aims to develop an electromagnetic launch system which can launch switchblade drone well.

# SOLUTION OVERVIEW:
The project involves the development of an electromagnetic launch system and a switchable drone. The launch system is designed to propel a fixed-wing drone to a relatively high speed, using electromagnetic forces. The drone is equipped with a switchable wing mechanism that allows it to be housed within the launching track during launch and then deployed for flight after exiting the launching system. There are several main steps to finish the project well:

Design and construction of the launch system
Development of the foldable wing mechanism
Integration of subsystems
Testing and validation Overall, the project's success will depend on the effective implementation of these solutions, which will require careful planning, design, and testing to achieve the desired outcome of a functioning electromagnetic launch tube with a switchblade drone.
# SOLUTION COMPONENTS:
The solution will consist of the following components:

Electromagnetic launch system: the system includes multiple sets of acceleration coils, a base to hold the coils, a base with both a guide slot for the horizontal movement of the ejection ram, and a launch cart to hold the drone.

Switchblade drone: the system includes the main body of the drone, a pair of foldable wings, a folding device powered by a torsion spring, and an attachment device for the drone to the ejection ram.

Electrical control system: the system mainly controls the charging and discharging of the coil, the main components are Hall Effect Sensors, N-Channel Power MOSFETs, MOSFET Heatsinks, High Speed Power MOSFET Drivers, Resistors, Momentary Switch.

# CRITERION OF SUCCESS:
The success of the project will be determined by the following criteria:

Portability: Weather the system is small and portable enough to be carried in a suitcase or other boxes.

Speed of the launched plane: The speed of the plane needs to be fast enough so that it can travel enough distance and realize some additional functions.

Safety: The system should not cause danger to the operator or other people around it. Potential dangers are, for example, Mechanical scratches and electric leakage.

Stability: The success rate of launching the plane, and the route of the plane after each launching should be similar.

# DISTRIBUTION OF WORK:
Shuyang Qian (ME): Responsible for designing and constructing the mechanical part of electromagnetic launch system including the guide rails, fixing parts and installation of coils.

# TITLE:

HIGH NOON SHERIFF ROBOT

PROBLEM:

Nowadays with the increasing number of armed attacks and shooting incidents. The update for public places needs to be put on the agenda. Obviously, we could not let police and security to do all the jobs since humans might neglect some small action of threat behind hundreds of people and could not respond quickly to the threat. A second of hesitation might cost an innocent life. Our team aims on making some changes to this situation since nothing is higher than saving lifes not only victims but also gunners. We find some ideas in the Old western movies when two cowboys are going to a high noon duel, the sheriff will pull out the revolver quicker than the other and try to warn him before everything is too late. If we can develop a robot that can detect potential threats and pull out weapons first in order to warn the criminal to abandon the crime or use non-lethal weapons to take him down if he continues to pull out his gun.

# SOLUTION OVERVIEW:

In order to achieve effective protection in a legal way, we have developed the idea of a security robot. The robot can quickly detect dangerous people and fire a gun equipped with non-lethal ammunition to stop dangerous events.

The robot should satisfy the following behavioral logic:

- When the dangerous person is acting normally and there is no indication of impending danger, the robot should remain in standby mode with its robot arm away from the gun.

- When the dangerous person is in a position ready to draw his gun or other indication of dangerous behavior, the robot is also in a drawn position and its arm is already clutching the gun.

- When the dangerous person touches his gun, The robot should immediately draw the gun, move the hammer and finish aiming and firing to control the dangerous person. This type of robot would need to include three subsystems: Detection system, Electrical Control system, and Mechanical system.

# SOLUTION COMPONENTS:

## [SUBSYSTEM #1: DETECTION SUBSYSTEM]

This subsystem consists of a camera and PC. We are going to use YOLO v5 to detect object, determine the position of human and the gun. Use DeepSORT to track the object, let the camera follow the opponent. Use SlowFast to detect opponent’s behavior.

## [SUBSYSTEM #2: ELECTRICAL CONTROL SYSTEM]

This subsystem consists of a STM32, two high speed motors, two gimbal motors, one motor for revolver action and position sensor. The STM32 serves as the controller for the motors. The high speed motor will be used to move the mechanical grab to grab the revolver and pull it out as fast as possible so that it will use the position sensor as the end stop point instead of PID control. The gimbal motors serve as Yaw and Pitch motion for the revolver to control the accuracy of the revolver so that it needs encoders to give the angle feedback.

## [SUBSYSTEM #3: MECHANICAL SYSTEM]

This subsystem consists of a three-degree-of-freedom robot arm and a clamping mechanism fixed to the end of the arm. The clamping mechanism is used to achieve the gripping of the gun, the moving of the hammer and the pulling of the trigger. The mechanical arm is used to lift and aim the gun.

# CRITERION FOR SUCCESS

- Move Fast. The robot must draw its gun and aim faster than the opponent;

- Warning First. If opponent’s hand moves close to the gun on his waist, the robot should draw the gun and aim it at the opponent without firing. If the opponent gives up drawing a gun and surrender, the robot should put its gun back in place. Otherwise, the robot will shoot at the opponent.

- Accurate shooting. Under the premise that the opponent may move, the robot must accurately shoot the opponent's torso.
