| + | All of the information is now available on a dedicated website. |
| − | The Kart module (214_Pr1) is a Summer School module for students between 3. and 4. semester. It's a home-made car remotely controlled by a smart-phone.
| + | <br> |
| | + | Please visit https://ss1.hevs.io/. |
| | | | |
| − | The work of the students can be summarized in four main tasks:
| + | [[Category:Kart]] |
| − | * design and build the chassis
| + | |
| − | * analyse the motor driver circuits (DC and stepper)
| + | |
| − | * configure the controlling FPGAs
| + | |
| − | * complete and extend the GUI on the smart-phone

| − | == System Architecture ==
| + | |
| − | | + | |
| − | The kart is controlled by a smartphone via Bluetooth.
| + | |
| − | | + | |
| − | === Distributed boards ===
| + | |
| − | | + | |
| − | A Bluetooth receiver on the kart communicates via an [[kart/serial link|RS232 serial link]] with the FPGA control board.
| + | |
| − | | + | |
| − | The control is distributed over several FPGA boards connected together via [[kart/I2C link|I2C]]:
| + | |
| − | * An I2C master receives RS232 controls, stores them in a set of registers and dispatches them at a regular interval on the I2C. The master also reads data values from the I2C, stores them into a second set of registers and sends the corresponding information at a regular rate over the RS232.
| + | |
| − | * A [[Kart/DC motor controller|DC motor controller]] receives a speed value and builds a PWM and a direction control.
| + | |
| − | * A [[Kart/stepper motor controller|stepper motor controller]] receives the desired angle and builds the coil controls signals.
| + | |
| − | * A [[Kart/sensor board|sensor board]] manages I/O comprising proximity sensors, hall sensors (for the driving speed) and LEDs.
| + | |
| − | | + | |
| − | === Bluetooth communication ===
| + | |
| − | A Bluetooth communication transfers serial port data.
| + | |
| − | A receiver chip creates the RS232 signals for the FPGA.
| + | |
| − | The [[kart/serial link#Serial link protocol|protocol]] defines how the [[kart/serial link#Registers|registers]] are accessed.
| + | |
| − | | + | |
| − | == Components ==
| + | |
| − | | + | |
| − | === FPGA Boards ===
| + | |
| − | The FPGA motherboards are equipped with an AGL125 [http://www.microsemi.com/products/fpga-soc/fpga/igloo-overview IGLOO] in a VQ100 package.
| + | |
| − | They connect to daughterboards which drive different parts of the Kart.
| + | |
| − | The motherboards are interconnected via an [[kart/I2C link|I2C link]].
| + | |
| − | | + | |
| − | Existing daughterboards are:
| + | |
| − | * the [[Kart/RS232 board| serial interface board]] or the [[Kart/Bluetooth Bluetooth interface board]]
| + | |
| − | * a [[Kart/DC motor controller|DC motor controller]]
| + | |
| − | * a [[Kart/stepper motor controller|stepper motor controller]]
| + | |
| − | * an [[Kart/sensor board|I/O board]]
| + | |
| − | | + | |
| − | === Sensors ===
| + | |
| − | | + | |
| − | The sensors connected to the I/O board are:
| + | |
| − | * 1 to 4 [[kart/sensors/VCNL4000|VCNL4000 I2C Distance/Ambience Light Sensor]]
| + | |
| − | * 1 to 2 [[kart/sensors/SS311PT|SS311PT Hall Sensor]]
| + | |
| − | * 1 [[Kart/sensors/HCSR04|ultrasound ranger]]
| + | |
| − | * 1 [[Kart/sensor board|end of turn]] contact switch
| + | |
| − | | + | |
| − | Additionally, the power supply board comprises an ADC which provides the [[kart/battery level|battery level]].
| + | |
| − | | + | |
| − | == Android App ==
| + | |
| − | One goal is to implement an Android application that controls and monitors to the kart.
| + | |
| − | | + | |
| − | === Introduction ===
