# Problem:

We live in a world with constant distractions. Sometimes we need personal space and time to think. What if there was a solution to reserve a seat in a library to facilitate this quiet time? This is necessary because not only is quiet time fundamentally important in today’s society but also seats at our favorite library, Grainger, are hard to come by because of the first-come first-serve system.

# Solution:

A solution to this problem would be a compact device that sends the status of seats to an online reservation system. The reservation system would allow you to select an open seat for an hour.

# Subsystems:

Power: This will power the desk module and its components from the wall. We will use an ac-dc converter to step the wall voltage down to power the desk reservation system.

Controller: The brain of our system is a microcontroller. This microcontroller will handle the communication between the wifi chip, display, and sensors. This microcontroller will need to have analog and digital inputs and outputs. In addition, the microcontroller has to support serial communication protocols.

Sensors: There will be an RFID sensor that will identify the individual who has requested the desk. Also there will be a proximity sensor to indicate if someone is occupying the desk.

Display: The LCD screen will display the status of the reservation.

Wifi: The wifi chip interfaces with the microcontroller and the database.

Mobile Application: On the front end, It allows you to select which desk you want to reserve. On the backend, it connects to a database.

# How are we different from other Desk Reservation Systems?:

This reservation system that we are building has four unique components. First, it accepts desk reservations from a mobile phone. Second, it also allows you to reserve an open desk on the fly with your unique RFID tag. Third, we enforce the time spent at a desk; there is a strict check-in, check-out process and a proximity sensor to verify if someone is occupying the desk. Fourth, if encroachment occurs, we will have a system to show the fees incurred for people overstaying their time.

# Vision:

The goal of this product is to accomplish the following type of workflow: The student reserves a particular seat in Grainger. The LCD on the desk then says the seat is reserved. The student arrives at the seat in a timeframe of 15 min and taps their RFID tag on the compact device; this signifies check-in. The student uses the desk upto an hour; there is a proximity sensor verifying that the desk is being occupied. When it is time for the student to leave the desk, the student taps the RFID tag on the compact device to signify check-out. The proximity sensor will confirm if the student left the desk. We would build 2-3 desk modules for our project. This will allow us to simulate a desk reservation system.

# Problem

WRSC (World Robotic Sailing Championship) is an autonomous sailing competition that aims at stimulating the development of autonomous marine robotics. In order to make autonomous sailing more accessible, some scholars have created a generic educational design. However, these models utilize expensive and scarce autopilot systems such as the Pixhawk Flight controller.

# Solution

The goal of this project is to make an affordable, user- friendly RC sailboat that can be used as a means of learning autonomous sailing on a smaller scale. The Autonomous Sailboat will have dual mode capability, allowing the operator to switch from manual to autonomous mode where the boat will maintain its current compass heading. The boat will transmit its sensor data back to base where the operator can use it to better the autonomous mode capability and keep track of the boat’s position in the water. Amateur sailors will benefit from the “return to base” functionality provided by the autonomous system.

# Solution Components

## On-board

### Sensors

Pixhawk - Connect GPS and compass sensors to microcontroller that allows for a stable state system within the autonomous mode. A shaft decoder that serves as a wind vane sensor that we plan to attach to the head of the mast to detect wind direction and speed. A compass/accelerometer sensor and GPS to detect the position of the boat and direction of travel.

### Actuators

2 servos - one winch servo that controls the orientation of the mainsail and one that controls that orientation of the rudder

### Communication devices

5 channel 2.4 GHz receiver - A receiver that will be used to select autonomous or manual mode and will trigger orders when in manual mode.

5 channel 2.4 GHz transmitter - A transmitter that will have the ability to switch between autonomous and manual mode. It will also transfer servos movements when in manual mode.

### Power

LiPo battery

## Ground control

Microcontroller - A microcontroller that records sensor output and servo settings for radio control and autonomous modes. Software on microcontroller processes the sensor input and determines the optimum rudder and sail winch servo settings needed to maintain a prescribed course for the given wind direction.

# Criterion For Success

1. Implement dual mode capability

2. Boat can maintain a given compass heading after being switched to autonomous mode and incorporates a “return to base” feature that returns the sailboat back to its starting position

3. Boat can record and transmit servo, sensor, and position data back to base
