# Title
Airport Baggage Robot

# Problem

Carrrying bags in airport is somehow inconvenient, because airport is to large and you need to carry the bag for a long time. We want to free our hands.

# Solution Overview

We plan to build a wheel-legged robot to carry the bags for customers. You can place the bag on this robot and it will automaticlly follow you via computer vision to the boarding gate. The leg control algorithm allows this robot to cross barriers like steps and steep ramps.

# Solution Components
## Subsystem 1
The gyroscope system used to balance the leg wheel robot
## Subsystem 2
5-links solver algorithm to control the position of robot legs to balance the robot.
## Subsystem 3
The visual algorithm is used to identify the following users and the path planning algorithm is used to plan the route and achieve the goal of avoiding obstacles. Since we are solving with the visual solution, so we will simply use a high resolution camera for recognition instead of 12 Vehicle radars. And the other components are mainly software-level.

# Criterion for Success
1. The robot is able to balance itself
2. The robot can adapt to different weights by adjusting its posture
3. At least can identify the person and follow the person. What is more, if the tracking path has obstacles, it can avoid them.

Problem:

The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
