What is Engineering?

Problem solving Design Innovation and Creativity Application of math and science Teamwork and Leadership Communication Professional

What do Engineers do?

Work in industry, government or consulting Develop surgical instruments Design municipal infrastructure (water

distribution lines, water treatment) Remediate a contaminated site Design a robotic systems for a production

line in a factory

Engineer or Scientist – What’s the difference?

Science – understand concepts, learn about theory and principles, have expertise

Engineering – applies principles of math and science to solve real-life problems

Engineers and scientists often work together as part of a team

Engineering is a profession – P.Eng

Design Engineering

Design courses starting in first year First year - marble launcher Second year - windmill powered

battery charger Third year - design of soccer playing

robots Fourth year design courses

The Mission:

Design, build and test a device to transport a marble from less than a foot off the floor into a column of water

Slow the descent of the marble to the greatest extent possible

Maximum time under water, not touching the bottom

The Rules:

You may attach a device to the marble You may not change the marble Human energy can only supply potential

energy to the launch mechanism If you add something to the water, it

must be added with the marble No explosives can be used

More Rules:

Made entirely by recycled materials

Constructed by the group Total equivalent cost less than $50 Safe for a nine year old to use No animals may be used/harmed

in the design

The column

Column 4 feet high Water to within 2” of the top A shallow sheet metal funnel will be

attached to provide a greater entry radius

Launch mechanism can touch the metal funnel but not the column or the water

The Criteria

How long does the marble take to descend to the bottom of the water column

Cost (cheaper is better) Aesthetic appeal Simplicity of design Unique, innovative design

Solution 1 – Elastic launcher

Launching arm on an elastic band, potential energy by drawing back the arm launches the marble

Adjustable to change the range of the launcher and improve accuracy

Solution 1 – Cork floater

Marble attached to cork – buoyant forces counteract the weight of the marble

Flat piece of cork acts to provide drag in the water

Solution 2 – Weight pulley on a ramp

Weight (pop bottle filled with nails) attached by string to ½ popcan holding the marble flotation device over a pulley (old inline skate wheels)

As weight falls, the can with the marble leaves the floor, rises to the column and tips the marble device into the column

Solution 2 – Oil capsule

Spherical capsule filled with canola oil (lighter than water)

Fishing weights and paperclips to balance weight

Solution 3 Counter-weight lift device

Elevator type lift – wooden structure with a angled platform

Free weights attached by string to the platform

Once released from the top of the structure, the weights fall, and the platform rises, releasing the flotation device into the column

Solution 3 – Water balloon

Marble in a large water balloon, diameter slightly less than the diameter of the column

Attached to a PVC pipe capsule containing alka-seltzer

When balloon is released, water leaks into capsule through a drilled hole

Reaction with alka-seltzer releases gas, increasing the balloon diameter

The Winner

Solution 3 – Maximum suspension (5 min)

Second runner up – Solution 2 (4 min)

Robotic Arm Demonstration

Analysis and bioremediation of contaminated soils

Pedobarograph Device for measuring forces during

teeth grinding/Bruxism Surgical Instrument for back surgery

Engineering Systems & Computing

Computer engineering (hardware) and Software engineering and Systems engineering

Embedded systems• Elevators• Microwaves• VCR• Car

Interaction – hardware, software, environment

4th Year Design Projects

Portable MP3 music machine Robotic arm application where arms

work in collaboration to complete a task Intelligent mechatronic aide for

recovering stroke patients Voice recognition and translation Home robot controlled via the internet

Research – Computer Vision Technologies

Robot that has vision and interacts with and tracks people

More sensitive than automated visual tracking

Applications – monitoring manufacturing, robotic arm routines and prevention of line shutdowns

GM – vehicle technology to prevent drivers from falling asleep, driver assistant for traffic surveillance
