Lab Equipment

The Srivastava Senior Design Lab has a wide selection of equipment that provides nearly all of the capabilities of the other ECE teaching labs in one place. Although the equipment may not be identical to that found in these other teaching labs, similar functionality is offered. Use the experience of learning new equipment as a way to expand your horizons. If you are using a piece of equipment for the first time, ask a TA for assistance, to make sure you understand how to safely use it. If the available equipment does not meet the needs of your project, talk to the course staff, and we will help you find what you need elsewhere on campus, consider purchasing it for the senior design lab (if it would be used by many groups), or brainstorm alternate ways to solve your problem.

Lab Kits

Each team is provided with at least one lockable storage drawer in the lab as well as a portable lab kit. An additional drawer and/or kit may be issued as need arises and facilities allow.

The lab kit includes a box with carrying handle and contains a wiring board for prototyping circuit projects, a multiple-output power supply, a digital multimeter, and a set of 8 cables (2 bnc/bnc, 2bnc/pin, 2 banana/banana, and 2 banana/pin). This is checked out to you by your TA at the beginning of the semester and must be returned undamaged at the end of the semester. Missing lab kits will result in an encumbrance or withheld diploma and a charge of $500.00, so always be sure to lock your lockers! Also, do not store any cables from the lab in your kit. Doing so will result in a loss of points.

Test Equipment

Most equipment is connected to the PCs via HPIB cables. Below is a sampling of the test equipment available:

Specific setups at the various lab benches can be in the listing at the bottom of this page.

Computers

The lab has PCs with enough processing power for the needs of nearly any senior design project. These machines are networked to a high-capacity laser printer (printing will count against your standard print quota). Each has an Ethernet connection to the campus network, an HPIB interface card connecting it to all of the standard instruments on its bench, and a sound card. The computers are maintained by Engineering IT, located in 3080 ECE Building.

The PCs are presently configured with the software shown here. Their primary uses include:

Autonomous Sailboat

Featured Project

# Autonomous Sailboat

Team Members:

- Riley Baker (rileymb3)

- Lorenzo Pérez (lr12)

- Arthur Liang (chianl2)

# 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
