Assessment Details

Part 1: Design Documentation and Peer Review

This stage requires you to select a problem to solve using one of the available Mindstorms Robots, design a possible

solution to this problem and submit this solution design for peer review. You are also required to peer review the designs

of two other students in the course.

The design documentation is to be completed in groups of 2-3 students. Your team will be allocated from your lab group.

Peer reviews will be completed individually.

Problem Selection

Identify a problem to solve as a team. You can come up with any problem of interest (perhaps a design thinking

workshop could help generate ideas?), or use the ideas below as suggestions. Your problem must:

• Be challenging for you. You are being assessed on your application of problem solving skills, so any problem

that is too easy will not give you the opportunity to demonstrate this.

• Require you to use a variety of problem solving strategies / techniques to complete

• Be creative. Fun is a huge element of a hackathon, so you want to select something that you will enjoy.

• Require you to code the behaviour. Controlling the robot’s movements through a remote is not permitted

(although a limited amount of this may be done in support of coded behaviours)

• Work within the capabilities of your robot. You are not permitted to modify the robot builds, other than to switch

between the available attachments as appropriate. You may add temporary enhancements, such as using glad

wrap, putting on temporary decorative clothing or applying a rubber band, provided the changes do not affect the

structure of the robot, do not impair its capacity to function, do not leave any mark or residue on the robot and can

be quickly applied and removed.

Your problem must also not be something that you can solve by following previously created instructions or downloading

existing programs. For example, you cannot just use the code examples provided in the Mindstorms tutorials, even if you

recreate them yourself, and you cannot download existing code from the internet.

Ideas:

• Sort objects in different locations based on colour

• Build something by collecting pieces and assembling / layering them in a specific location

• Play hide-and-seek, using an IR sensor to locate the IR remote

• Battle another robot (two teams from one lab group could each program one robot to compete). Just remember

not to damage the robots!

• Follow a path through an unseen obstacle course – perhaps use colour, or object sensing (or both?) to determine

movements

Design Documentation

Once you have selected a problem, your team must create documentation that outlines the logic of a solution to your

problem. You may need to break your problem down into smaller sub-problems to achieve this, and should prepare

problem statements for these sub-problems. This documentation must clearly identify the problem(s) you are attempting

to solve, and include algorithms and UML models to represent the full functionality of the program(s) you intend to

implement during the hackathon. Your documentation must be saved in .pdf format.

Completed design documentation must be uploaded to the two links provided in Moodle by noon Monday 3rd September

2018 to allow time for peer reviews to be completed.

Each student needs to submit the same version of their group design document twice (Hackathon – Solution Designs

Workshop and Assignment Part 1: Design Document).

The reason for this is that the Hackathon – Solution Designs Workshop submission is where you will peer-review other

design documents (including your own) and the Assignment Part 1: Design Document submission is where your tutor will

mark your groups’ design.

Peer Reviews

From noon on Tuesday 4th September 2018 (or an alternative time as advised by your lecturer), you will have access to

conduct a peer review on two other students’ design documentation (through moodle). These reviews will be allocated to

you. You will also review your own design. These designs will be selected from different teams where possible, which

means each team will usually receive feedback from six other people. You will complete the peer reviews individually.

Your task is to review the documentation allocated to you and to evaluate it against a set of criteria provided in a marking

rubric. You should consider how well the documentation defines the problem(s) under investigation, how clearly

algorithms represent and address the problems(s) and how effectively UML diagrams are documented to solve the

problem(s). You will also have the opportunity to provide your own comments, and should take care to provide specific

comments that highlight both the positive aspects and the potential issues of the proposed solution(s) and documentation.

Note: Your mark will not be impacted by the feedback your peers provide on your work. Your tutor will be

marking your design documentation separately, and it is your tutor’s mark that will contribute to your assessment.

You will be marked based on how well you complete your peer reviews.

All feedback must be completed by 23:55 Sunday 9th September 2018, in readiness for the hackathon to begin in the

next workshop. You should review the feedback you have received and incorporate the feedback you receive into your

design, as appropriate. You may continue to update your documentation throughout the hackathon, based on your

hackathon experiences, and any additional ideas you obtain through seeing the designs completed by other people

(Note: this does not mean copying their work. It does mean that you can be inspired by it, and make improvements to

your own design based on what you’ve learned).

Part 2: Hackathon Report

This part of the hackathon assignment requires you to discuss, analyse and reflect upon the problem solving

techniques you use during the hackathon. This will occur through a work journal, to be documented in your

ePortfolio. This task is to be completed individually.

You will update and maintain your work journal on a frequent basis throughout the hackathon,

documenting:

• an overview of the work you have been attempting

• challenges or problems you encounter

• the output of your work.

Throughout these journal entries, you will make and analyse connections between the work you are

performing and the course concepts reviewed throughout the semester. For example, if you attempt

to solve a problem using a graphical model, your entry would identify the problem you were trying to

solve, discuss the use of the graphical model and the reason for its use and analyse how effective the

graphical model was in helping you resolve the problem.

You will also reflect on your learning throughout the hackathon. This learning can include both course

concepts that you understand better due to applying them during the hackathon, and learning about

yourself as a problem solver.

To create your Work Journal:

1) Log on to Mahara (ePortfolio System) at https://eportfolios.federation.edu.au/

2) Select Content, then + Create journal

3) Give your journal a name, e.g. ITECH1101 Hackathon Experiences

The work journal does not need to document every single aspect of the work you perform during the

hackathon, and does not need to address all of the marking criteria in every entry. Rather, the journal

entries as a whole need to provide insight into your experiences in the hackathon and it is these

experiences as a whole that will be evaluated. An example of the format for a single journal entry is

included below:

Supporting Documentation

Effective completion of your work journal will involve referencing documentation that you have created

for the hackathon. Examples of this include UML models, tools for problem solving, code, test cases

and test results.

You are required to upload the documentation you discuss into the work journal. This documentation

may change as you work through the hackathon, so uploading it in the entries as you progress

provides a record of how your work evolves throughout the hackathon and enables other people to

understand the context in which your journal entries are made.

Journal Entry: Day 8

Tasks Attempted Today: Coding of requirements 5, 8.

Finally made a breakthrough on the issue I had trying to get the robot to stop as per requirement 5. I realized it had to be an error with the logic of the code somewhere, so I revisited my activity diagram and worked through it step by step. It seemed okay, so I then compared it carefully with the code I’d created in Mindstorms. It turns out I hadn’t set the switch up correctly inside the loop, so the code to stop was never being reached. I found it much easier using the activity diagram to compare with my code because I could then just concentrate on making sure the code exactly followed the activity diagram’s structure. When I had tried reviewing the code directly without the activity diagram, I got lost (without realizing) trying to keep track of what the code was doing and the logic of what I wanted the code to actually do. It was such a relief to finally fix this issue and it gave me confidence that I can actually do this if I put the effort into thinking about it.

We started working on requirement 8 this afternoon in our lab. Using the sensor is tricky because we weren’t sure about its working range, so we wrote a program and tried it out on the robot a few times, changing the distance setting to see what happened and recording our results, using a table as our graphical organizer. This combination of trial and error with recording the results in a table worked effectively as we now understand what the different values mean and can incorporate this into our program.

Part 3: Hackathon Presentation

At the conclusion of the hackathon, each person must provide a short individual presentation about their hackathon

experiences in their scheduled laboratory.

This presentation will:

• introduce the main problem that the team attempted to solve for the hackathon.

• identify a personally-significant moment experienced during the hackathon and discuss what made this

significant. A significant moment may include events that were challenging, particularly emotive (satisfying,

frustrating, etc) or that had a large impact on the work performed during the hackathon.

• identify ONE problem personally encountered during the hackathon, and discuss the problem solving techniques

or strategies used personally to address this problem and how (and why) these were used. Note: team members

must not choose the same problem to discuss. You will need to coordinate with your team to ensure different

problems are selected.

• reflect on personal learning and responses to challenges encountered during the hackathon, including

understanding of course concepts, personal skills in problem solving and the role of mindset.

Each presentation should not exceed 5 minutes. Any presentation aids readily available to students may be used, but

students are responsible for ensuring these will work in the labs and having a backup available in the event of an issue.

You are also required to complete a peer review of two presentations conducted by other students in your laboratory

class. You will be allocated two student presentations to review at the start of the laboratory class. Peer review forms will

be provided in the class.

Submission

Your initial design documentation must be submitted in the Workshop and Assignment link provided in Moodle, as a

.pdf file. Your peer reviews will also occur directly in this Workshop link.

Your work journal must be created in the Mahara ePortfolio and submitted in Moodle at the assignment dropbox

provided. This must be separate from your ePortfolio journal entries.

Your documentation, including all code, models, test cases and test results, must be zipped into a single file and

submitted in the assignment dropbox provided. This includes the final version of the design documentation, incorporating

any changes to the documents that occurred during the hackathon, and the final version of any supporting documentation

referenced in your work journal. You will also submit a copy of the feedback you provide to your peers on their

presentations in the week 11 lab in this link.

Your presentation will be assessed during your scheduled lab class in week 11.
