SDP - GROUP 18 - 2017/18
RoboTour is a robotic tour guide that assists people in environments such as museums or art galleries. The system comprises an autonomous robotic guide, a purpose-built Android application, and a web server mediating the communication between the two. Up to two Android devices can control RoboTour and followed by many more. The app allows users to interact with RoboTour intuitively in multiple languages. RoboTour has been designed for minimal maintenance; once the initial setup has been performed.
The System Design Project is intended to give students practical experience of
(a) building a large scale system
(b) working as members of a team.
The Systems Design Project is a University of Edinburgh, Semester 2 module, SDP is a group project involving the construction of an item of significant complexity under conditions designed to give insights into industrial teamwork.
It is a 20 credit course with design, construction and assessment through the semester, ending in a demonstration day with industry visitors.
More detail about the course and how it will run this year are in these slides from the introductory lecture held in semester 1 Professional Issues.
SDP 2017/2018's task is to use Lego and an Arduino to design an assistive robotic device, with an appropriate software interface.
Flexibility was given to set your own goals for this task, but here is an example of what you could attempt: a person indicates an object on the floor with a laser pointer, and the robot picks it up and returns it to the person.
The class is assigned to groups of 7 or 8, each responsible for the development of a single robot. Assessment involves group marks for the product (performance and documentation of the robot systems).
Each group had an assigned mentor, with whom they meet around once a week, and who offers advice and monitors progress, but - importantly - does not lead or manage the group. Advice on how the group should organise themselves for good project management will be provided. Problems within the group should first be brought to the attention of your mentor; if you have an issue with your mentor, you should bring this to the attention of the SDP TA (see below).
The project involves applying and combining material from several courses to complete a complex design and implementation task. At the end, of course, each group demonstrates its implemented system and gives a formal presentation to an audience of the students, supervisors, and visitors from industry (E.g. Google, Amazon, KAL, Robotical).
The project was developed for System Design Project at the University of Edinburgh. All 20 projects were assessed by external judges from industry (e.g. Google, Amazon, Accenture, KAL, Sky). Team RoboTour was awarded the Technical Innovation Prize
RoboTour provides four key features to enhance the user’s experience
- Multi-language support in Human-Robot Interaction via speech and app
- Guides visitors to a specific art piece and points it out to the user
- Plays audio description of art pieces in the language the user selected
- Provides recommendations and optimal route planning routes
RoboTour assists people who have one of the following problems:
• They’re a museum visitor who needs directional assistance
• Or they’re a visitor who cannot read the displays in the museum whether this is because they cannot read the language or because they have problems with their vision.
RoboTour robot can interact with visitors and guide them to the piece of art they are looking for by moving with the user through the museum and pointing out the art piece upon arrival.
There are three main components to RoboTour:
- Android App - Responsible for allowing the user to select paintings they wish to go to and send commands to the robot.
- Server: All Android devices communicate to the robot via the server. The server is responsible for mediating and storing commands between all Android devices and the robot. The purpose of having the server is to allow multiple android devices to communicate with the robot.
- Robot: Oversees path planning and navigation around the museum
The app is backwards compatible with older versions of Android; the app will work with Android SDK version 17 onwards (users also require 20mb free space and an internet connection). The app was developed in Android Studio 3.1 using Kotlin.
The robot is a differential drive platform, i.e. the movement is achieved with two motorised drive wheels. Varying the rotational speed of the wheels independently, allowed us to introduce rotation of the chassis in addition to the linear translation. Additionally, two rear wheels are added for stability and weight support. They were designed with the aim of minimising the friction and disturbance of the robot control.
To install the app on an Android device, installation, you are required to enable [Unknown Sources](https://www.androidcentral.com/unknown-sources).
This feature is turned off by default on stock Android, and can be turned on by following these steps:
Device Settings -> Advanced Settings -> Security -> Enable Unknown Sources
Once the app is downloaded, go to the Downloads folder on your phone and click on the apk or select it from the notifications bar. Follow the installation instructions. Once installed the app will be in your App drawer under RoboTour. Tap the app to open it.
