Getting Started Students must complete this activity before attempting any other activities.

In this tutorial we will guide you through building a basic frame, and show you how to use all the different pieces of equipment.





Fire Engine Construct a fire engine and its ladder.

Build a mechanism for raising and lowering the ladder.

Measurement, Leverage, Electronics, Logic.





Burglar Alarm Build a spring loaded alarm system.

Trigger this when a window is opened or with a trip rope.

Pimp your alarm using laser beams and mirrors.

Pulleys, Mechanisms, Problem Solving, Electronics





Caveman Car Build a rubber band powered caveman vehicle.

Modify the vehicle to achieve extra speed and distance.

Energy, Measuement, Practical Mathematics





Bridge Construct a bridge that can cross a 2.5m wide river.

Use bracing to make the bridge rigid and capable of carrying a 2kg test vehicle.

Add traffic light to control the flow of vehicles over the bridge.

Structures, Bracing, Measurement, Electronics





Robotic Guard Dog Build a guard dog shape.

Ropes make its jaws hinge and tail wag.

Motorise it and have it triggered to bark when a burglar breaks a laser beam.

Structures and Mechanisms, Electronics, Problem Solving





Crowd Size You have a drone photo of the a massive concert in your town.

Build frames to experiment with crowd density.

Use practical maths to estimate the number of people in the crowd.

Practical Maths, Measurement, Problem Solving





Storm Proof Dog Kennel Construct a dog kennel that can withstand floods, rain and hurricane forced winds.

It will have a flood level alarm and a drawbridge that will automatically close when it is flooding outside.

Structures, Bracing, Measurement, Leverage, Electronics





Party Popper Design a contraption that can automatically fire a sequence of party poppers.

Use ropes and pulleys so that the party poppers can be fired in multiple directions.

Pulleys, Problem solving, Electronics





Helicopter Rescue Suspend a model helicopter from a giant rig using four ropes.

Using only the ropes, work as a team to control the helicopter.

Teamwork, Geometry, Measurement, Problem Solving, Structures, Angles





Secret Agent Develop a code that can be used to send a message using a pattern of long and short signals.

Construct a mechical and an electrical system for sending these signals.

Patterns, Electronics, Problem Solving, Communication





Crane Build a crane that can lift a weight to a height of 1.8m.

Use pulleys to make it easier to lift the weight.

Motorise the crane for automated operation.

Structures, Pulley Theory, Electronics





Rope Swing Build a swing

Experiment with what effects the speed of the swing

Graph your results.

Structures, Experimental Method, Practical Maths, Measurement, Graph





Gearbox Build a gear box that can speed up or slow down an arm.

Think about the maths and ratios behind a gearbox

Mechanisms, Practical Maths, Rations





Laser Tracking Use a torch and a magnifying glass to create a spotlight.

Build a motorised stand that can control the direction of the beam.

Use this to track a meteor.

Optics, Mechanics, Electronics, Angles, Practical Maths





Fishing Rod Build a fishing rod.

Modify the reel to wind the rope in extra fast.

Design a sensor to automatically detect when you have caught a fish

Mechanisms, Gearbox, Pulleys, Electronics





Rowing Machine Construct a rowing machine using a weight as resistance.

Different combinations of pulleys will make it easy and difficult to lift the one weight.

Pulleys, Weights, Measurements





Drum Machine Construct a drum kit, and a drum machine that can play the drums as a handle is turned.

Add a gearbox so it can play a very fast drum roll.

Mechanisms, Electronics, Problem Solving





Limbo Take the classic party game, and turn it into a crazy EPro8 style contraption.

The contraption will have fail alarm, automatic level adjustment and scoring.

Measurement, Pulleys, Problem Solving, Electronics





Bungy Jump Construct a Bungy Jump Platform

Experiment with rubber bands to achieve the ultimate rebound

Structures, Experimental Method, Measurement, Graph





Air Freight We are sending some EPro8 Equipment to Mongolia.

Build a set of scales to find the weight of the equipment.

Calculate what it will cost to air freight these items to Mongolia.

Balance, Leverage, Weights and Measurements, Practical Maths





Flying Fox Build two towers and a flying fox to access your house on the other side of a "river".

Motorise the flying fox so you can come and go in either direction

Pulleys, Forces, Vectors, Mechanisms, Structures, Electronics





Royal Wave Construct the Royal Limousine, with an arm that waves automatically.

Make the arm wave as the limousine is pushed along the ground.

Make the arm wave extra fast

Mechanisms, Gearbox, Electronics
