Congratulations to the Aurora team for 2nd place with a very ambitious (and successful) design which went way beyond the requirements set for the challenge. The team, consisting of 4 students aged 17 (S6), used a huge range of skills to design and develop their competition entry with prototypes and the final design printed on their Robox 3D printer.
Some details about the team from their excellent website www.aurorasat.space
Who are we?
We are a CanSat 2016 team from Glasgow, Scotland. The team consists of four pupils from Hutchesons’ Grammar School. Our supervising teacher is Dr Walker, and our sponsors are Pulsion Technology and CEL Robox.
What is CanSat?
A CanSat is a simulation of a real satellite, integrated within the volume and shape of a soft drink can. The challenge for the students is to fit all the major subsystems found in a satellite, such as power, sensors and a communication system, into this minimal volume. The CanSat is then launched to an altitude of a few hundred metres by a rocket or dropped from a platform or captive balloon and its mission begins: to carry out a scientific experiment and achieve a safe landing.
Why do it?
CanSats offer a unique opportunity for students to have a first practical experience of a real space project. They are responsible for all aspects: selecting the mission objectives, designing the CanSat, integrating the components, testing, preparing for launch and then analysing the data.
Measure air pressure and temperature. Minimum 1 result per second transmitted to ground control/computer.
• Our can will split into two parts, and will land in two different areas on the ground.
• The can will split horizontally; the top part will land using a parafoil to glide to the ground, and the bottom part will land using a quadcopter-like motor/propeller system to navigate to the ground.
• The aim of the mission is to successfully demonstrate the splitting of the can, demonstrate two different landing systems and demonstrate the prospect of comparing two separate sites on one mission.
Optional – Targeted landing to both sites using high accuracy GPS and autonomous movement.
Optional – Rover on ground to pick up two capsules and return them to team base.
Optional – Implement camera to capture splitting of cans.
Small space to fit 2 satellites. Designing a modular system to access parts easily and still retain a strong structure was challenging.
New pyboard with very little online guidance or information, we had to program and wire everything based on our own knowledge.
Brushless motors and ESC’s are fiddly to set up and get going.
Designing and constructing a stable Para-foil.
Programming in a new language and programming electronics and understanding how they function together.
Learning how to use inventor and rendering the simulations of the satellite.
Using a 3D printer, learning how different plastics behave and how best to print small scale intricate models.
CAD software used:
Autodesk Inventor Professional 2016
Other software / programming tools used:
Command Line Tools
Robox made the following possible:
Printing of our satellite using ABS and PLA plastic. The Robox support team helped us to with recommendations and settings to ensure each part was accurately printed.
Other resources used:
Technology department supplied the majority of the equipment used, including soldering irons, hobby drills, glue guns, desktops.
Our other sponsor Pulsion supplied us with the £500 budget we had to stick to.
Physics department supplied digital callipers and high accuracy balances.
The Robox 3D printer we have was purchased by 3 of our Arkwright Scholars and is kept in the Technology department for students to use on request.
The Scalextrics club, which is aimed at younger years, design and build model rc cars. They have already printed one model.
The Formula 1 club also uses the 3D printer.
The printer will be used for further competitions. (possibly the Google science fair or other independent projects)

A note from the team leader:
I would like to thank you once again for not only sponsoring us and helping us when we had problems using the 3D printer but also for your kind words throughout. You have motivated us and kept us going when certain aspects of our project didn’t turn out the way we wanted it to. Your quick and informative responses have aided us greatly. – Rishabh
