Storyline
Nemo is a young clownfish who lives with his best friend Dory in the Great Barrier Reef. Nemo and Dory have been feeling sick for a couple of weeks now, and they suspect that it is due to marine pollution. Seeing their families and friends passing one by one, fear pushes them on an adventure in search of a new home. They swam against currents, across beaky predators, into an aquarium in a dentist’s office, down the toilet bowl, and finally into their new home.
Marine pollution is a growing problem in today’s world. Our irresponsible use of trash damages the environment, the health of sea animals and affects the economic structures worldwide. The trash in oceans poses dangers to both humans and animals. Fish become tangled and injured in the debris, and some animals mistake items like plastic bags for food and eat them. Fishes like Nemo and Dory all deserve to live in a clean and safe environment. Every action has an equal and opposite reaction. With our 'actions', let us all do our part to protect them and the sea.
Project objective
To develop a device that can launch a ‘ball’ five times over a clear zone and into a horizontal ring of 50 mm inner diameter. The ring is located 300mm above the top surface of a table and is attached to a flat backboard as shown in Figure 1. The device will be placed on top of the table.
Project constrains
• Use recycled materials
• Design 2~3 components for the device, and then fabricate them using 3D Printing.
• Once the ‘ball’ is released, there should not be any more contact between the device and the operator.
• The ‘ball’ must ‘fly freely’ unguided in air and through the ring. It may bounce off the backboard before entering the ring.
• The device must be able to register the number of times the ‘ball’ goes through the ring.
• Credit will be given to innovative ideas and designs that do not make use of electrical and electronic components.
• Hydraulic power in any form (including water, chemicals and ignition) should not be used.
