Dear all,

We are happy to announce that the deadline for the AFRON 2013 Design 
Challenge for the "Ultra-affordable Robot" has been extended to 15th 
January 2014. The extended deadline provides a greater opportunity for 
university students to participate in the challenge during the upcoming 

With support from the IEEE Robotics and Automation Society, this design 
challenge focuses on enhancements to the robot designs from the 2012 
challenge, software development, and teaching plans. Details are below, 
and on the web at http://www.robotics-africa.org/2013-design-challenge. 
We look forward to your participation!

Best regards,
Ayorkor Korsah & Ken Goldberg
co-Founders, African Robotics Network

Announcing Extended Deadline: 15 January 2014

The Ultra Affordable Educational Robot Project
2013 Design Challenge: Robot Enhancements, Software, and Teaching Plans

Sponsored by:
The African Robotics Network (AFRON) and IEEE Robotics and Automation 

Robots excite people of all ages. Their physical behavior often inspires 
primary and secondary student interest in computers, science, math, and 
engineering more broadly. However, existing platforms are often too 
expensive for students. This project aims to collaboratively create an 
Ultra-Affordable Robot (an order of magnitude less expensive than 
existing products) to inspire young people around the world.

The 2012 Design Challenge 
(http://www.robotics-africa.org/2012-design-challenge) emphasized an 
ultra-low-cost robot hardware platform in three categories: tethered, 
roaming, and all-in-one. The winning designs were all highly creative, 
and the Grand Prize in the tethered category went to Lollybot, a 
brilliant design by Tom Tilley of Thailand, costing just under 10 USD 
and incorporating two functional Lollipops. Starting with a generic 
dual-shock game controller, Lollybot can be built using commonly 
available tools anywhere in the world.

In the 2013 Design Challenge, our goal is to create incentives for 
designers to select any of the winning designs from 2012 
<http://www.robotics-africa.org/2012-design-challenge> and work on 
enhancements in one or more of 3 categories: 1) hardware 2) software, or 
3) curriculum. This year, we are placing a special emphasis on Lollybot, 
encouraging next steps in the 3 categories: 1) enhance the Lollybot 
hardware design, simplifying assembly, increasing robustness, adding 
useful features, 2) extend and improve the open-source software for 
Lollybot, and 3) create exciting lesson plans using the Lollybot. In 
addition, there is a special “community challenge” for participants who 
organize a robotics workshop for students using one of the winning 
designs, with or without enhancements.

Competition Categories
1) Hardware enhancements
Propose design enhancements to make the chosen robot more effective, 
robust, re-usable, and even easier to assemble or manufacture. For 
example, possible design enhancements for the Lollybot include:
· Improved robustness (particularly of wheels and bumpers) to allow for 
more reliable behavior
· Ability to design and switch in and out different sensor circuits, 
such as the current line sensor circuit.
· Ability to control the robot with an old feature phone, a Raspberry 
Pi, or other low-cost computing platform

2) Software enhancements
Further open-source software development to add functionality to the 
chosen robot, and more importantly, make it easy for high school 
students with no prior programming experience to learn how to program 
new behaviors for the robot. For Lollybot, this could include, for 
example, a drag-and-drop programming interface, or a software interface 
to introduce basic features of JavaScript for programming the robot.

3) Curriculum
Outline 20+ hours of educational activity using the chosen robot. The 
educational value could come from the process of assembling the robot 
and from programming it. However, at least 15 hours of the curriculum 
should be re-usable, meaning that it can be used with an 
already-assembled robot. This ensures that learning continues after the 
robot is assembled for the first time. The lesson plans can assume a 
basic age-appropriate science and math background, but should not assume 
any background in robotics or prior experience programming or using 
tools such as a soldering iron -- it should help students learn what 
they need to know.

4) Community challenge
Build one of the winning designs in collaboration with students 
(primary, secondary or early college), documenting the process and the 
learning experience for the students.

Each category attracts a grand prize of $500, and a runner-up prize of 
$250. A single entry can win in more than one category. Additionally, 
there will be “honorable mentions” for other creative submissions.

The competition is open to individuals, teams of individuals, or 
institutions from anywhere in the world. We welcome submissions from 
hobbyists and students, in addition to professionals. For the community 
challenge, entries are particularly encouraged from participants working 
with students in Africa.

Submission Deadline
15th January 2014. Winners will be announced in February 2014

What to submit, and how
Create one HTML webpage with the following information:

1. A high-level description of your hardware enhancements, software 
enhancements, curriculum and/or student workshop.

2. For hardware enhancements, include:

a. A list of parts, their sources (include URLs if applicable), 
availability, and prices.
· Note that your parts list should be complete, including things like 
required adhesive, screws etc.
· Note that salvaged parts are allowed, if these salvaged parts are 
commonly available in your particular context. Think of this list of 
parts as the starting point if someone in a similar context to you 
wanted to reproduce your robot.
· Your parts list should include any consumables (e.g. batteries) and 
their associated cost and replacement frequency. This is a caution to 
think of sustainability.

b. A list of tools/equipment needed to create the robot, and estimated 

c. Relevant drawings with dimensions.

d. Step-by-step instructions for creating your robot

e. A description of any experiments conducted

f. Pictures and videos of your robot in action

3. For software, include:

a. A link to documentation (a “user guide”) for your software

b. If relevant, screenshots of your software

c. A link to the open-source software.

4. For curriculum, include:

a. The target age range / level (e.g. primary school – approximately 
below age 12, junior high or middle school – approximately between ages 
12 and 14, and senior high school – approximately between ages 14 and 18)

b. The learning goals

c. Materials needed

d. Activities

5. For the community challenge (student workshops), include:

a. The robot that was used

b. Information about participants (number, age range, location)

c. Sources of parts for robot-building

d. Description of activities

e. Description of outcomes

f. Pictures and/or video

Please share with us your intent to participate via this form 

When you are done, you can then make your final submission via the 
submission form <http://bit.ly/submit-afron-2013-challenge>, which asks 
for your name, contact information, and the URL of your webpage. Note 
that by participating in this competition, you agree to have your 
designs or curriculum published on the Internet (and attributed to you, 
of course).

Hardware enhancements will be assessed using the following criteria:
· Robustness & effectiveness
· Cost (try to stay below 20 USD, excluding computing)
· Versatility
· Ease of assembly

Software will be assessed using the following criteria:
· Effectiveness
· Ease of use
· Quality of documentation

Curricula will be assessed using the following criteria:
· Clarity
· Potential to help students learn
· Potential to engage students’ interest

The community challenge will be assessed using the following criteria:
· Completeness of documentation of the experience
· Creativity
· Student impact
