My group and I noticed a trend. Specifically, the process of ordering a drink in a crowded bar is extremely inefficient. Customers often have to wait long periods of time to have an order completed, bartenders often steal from the bar, and automating the process would remove the need for tipping and the need for bartenders.

Our idea is to design an automated bartender to improve the efficiency of the bartending process so less time is spent waiting. We also want to make the process cheaper, and to guarantee the safety and authenticity of the beverages served. On a high level, we hope to create a system which will allow guests to order beverages from a mobile device, and dispense them securely and safely.

We will have a series of tubes and valves, as well as some hardware controllers to actually pour the beverage. The users will be able to order their drinks remotely on an app, and pay through the interface as well. Then, the system will pour the mixed drink behind a shield. The person who purchased the drink initially will receive a QR code to scan to identify themselves. They will have a limited amount of time to retrieve their order before it is dumped out, in order to not hold up the machine.

For a Minimum Viable Product prototype, we will have an application which will allow a user to order a (nonalcoholic) mixed drink from a device, which will have an assortment of beverages in it. The device will mix them in a dispensed cup, and authenticate with the user to deliver the drink.

We feel this idea has business value to any bar owner who wishes to cut costs and improve efficiency. The automation of the entire process would add some novelty to their business, and make them stand out from the competition.

# 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
