THE TIN SOLDIER

 My task was to design and construct an electro-mechanical machine that dispenses an item whilst providing an experience. 

The machine could not exceed 300mm x 210mm x 300mm in size and as a minimum requirement had to include a stepper motor, 2 sensors, mechanical parts and ensure it provided a clear feedback signal to the user. 

As this was during Covid, I worked remotely and there was no access to basic construction materials so I had to utilise environmentally friendly and recyclable materials like cardboard. I still had to ensure that these materials maintained their structural integrity during user interaction but also could be easily disassembled for recycling at the end of the product's lifecycle.

I had brainstormed a few fun ideas but I had settled on the concept of a spinning head as it allowed me to introduce a fun game element into the vending machine's programming which I achieved using Arduino.

Check out my full report and methodology at the bottom of this page.

The Tin Soldier contains sweeties inside his head. Emblazoned on his lapels are a red and green LED which are the focal point for the following game. 

In order to successfully win sweets from this vending machine, you must first turn him on via the red button on his shoulders. The LEDS will start to flash and now you must press the button again to stop them flashing and have one LED become a solid light. 

But here is the challenge! Stand to attention.

You must press the button in time to ensure the green LED becomes a solid light in order for the head to successful switch and happily dispense you sweets. 

If you land on the red LED the head will scornfully shake side to side and glare at you as you have failed your mission. No sweeties for you corporal!
