# BIKE THEFT LOCK & CHAIN DETECTOR (UPDATED)

# PROBLEM
In the Champaign-Urbana area, it is estimated that around 856-1070 bikes are stolen each year (bikelab.com), with most perpetrators going unapprehended and missing bikes seldom recovered. Bike theft often goes unnoticed, especially if the crime occurs at night or with few witnesses.

# SOLUTION

The proposed solution is a cable bike lock that detects when the cable is cut by passing current through the cable and building a sensor to detect an open circuit. When the cable is cut, our cameras positioned on the cable and bike will record images that may potentially identify the criminal. The cable will also send out a signal to an alarm, as well as relay all this information to the user via bluetooth/Wifi connection.

# SOLUTION COMPONENTS

## SUBSYSTEM 1: OPEN CIRCUIT DETECTION

This system will pass a small current through the cable, using the cable and analog components to create a circuit. When the cable gets cut, the circuit would open and this would send a signal to the microcontroller indicating that theft is taking place.

## SUBSYSTEM 2: IMAGE CAPTURING VIA CAMERA

Once the microcontroller detects the open circuit, the camera modules connected to the microcontroller will take an image that the user will be able to receive via bluetooth connection, potentially providing key evidence to identify the perpetrator.

## SUBSYSTEM 3: SOUND ALARM

When the inductance is changed, the microcontroller should send out a signal to electronic alarm devices to alert the user or anyone nearby to someone trying to cut through the cable. The user will then receive a notification on their phone with an option to turn off the alarm, or the alarm will sound for a set amount of time.

# CRITERION FOR SUCCESS

Our device will be able to:

- Detect when the cable is cut
- Send a signal to sound an alarm when the cable is cut
- Take a picture as the theft is being attempted
- Relay the images and alarm sounding to the user's phone

Cypress Robot Kit

Featured Project

Cypress is looking to develop a robotic kit with the purpose of interesting the maker community in the PSOC and its potential. We will be developing a shield that will attach to a PSoC board that will interface to our motors and sensors. To make the shield, we will design our own PCB that will mount on the PSoC directly. The end product will be a remote controlled rover-like robot (through bluetooth) with sensors to achieve line following and obstacle avoidance.

The modules that we will implement:

- Motor Control: H-bridge and PWM control

- Bluetooth Control: Serial communication with PSoC BLE Module, and phone application

- Line Following System: IR sensors

- Obstacle Avoidance System: Ultrasonic sensor

Cypress wishes to use as many off-the-shelf products as possible in order to achieve a “kit-able” design for hobbyists. Building the robot will be a plug-and-play experience so that users can focus on exploring the capabilities of the PSoC.

Our robot will offer three modes which can be toggled through the app: a line following mode, an obstacle-avoiding mode, and a manual-control mode. In the manual-control mode, one will be able to control the motors with the app. In autonomous modes, the robot will be controlled based off of the input from the sensors.
