Braking System Team Meeting and Concept Overall

The current status of our Braking System project and progress are listed below. Please keep in mind, these concepts are subject to change. This is not the final concept, and it will change depends situation.

Project Role

Project Manager, Linux Operator: Abu Bakar Sakif
Python Developer: David Austin, Qili Jian
Android Developer: Qili Jian, Abu Bakar Sakif
Android UI Design: Chakman Fung, Gary Martorana
Code modifier: Abu Chowdhury

Bill of Material 

• Relay (connect to Raspberry pi and Electric motor or clamp)
• Electric motor (backward for braking)
• Electric clamp (clamp the rotor for braking)

Two Types of Braking System

• Electronic Braking System (Using ultrasonic Sensor) 
• Disc Braking System ( will be simulate in the project)

System requirement

• The vehicle should stop within a reasonable distance.
• When brake applied, it should give message to lighting system to turn on the braking light.
• Using Nexus tablet to control the communication between Android and Raspberry Pi
• When brake applied, it should have braking actions going on in the clamp or electric motor.
• Ultrasonic Sensor should detect obstacle in front of the vehicle and apply brake as needed or cut down the engine. 
• Anti-skid braking system ( if achievable).

Android UI

• Display a button to apply the brake (Mechanical Braking System)
• Display a button to turn on E-Brake ( Electronic Braking)
• Display a button to turn on ABS (Anti-lock Braking System)

Meetings Times :

• Monday : 5:20 pm to 6:00 pm
• Friday : 5:20 pm to 6:00 pm

Previous Meetings :


08/26/16 : Discussion on what needs to be done for Braking System
09/17/16 : Discussion on Android development
09/21/16 : Discussion on the requirements and development

Meetings after class done every week to follow up on progress.

Braking System will be using a relay to simulate braking. The GoPi Go will use the ultra sound sensors to detect approaching object and cut power to the engines and run the wheel backwors if needed.
