My client had a backyard, over 70%

of which was shaded by the tree near

her house and the ground is filled with

rocks and stones. Our design was

aimed to renovate her backyard into

a garden without removing the tree.

My team and I design an artificial

sunlight lamp system to resolve the

lighting problem. Combined with soil

base and watering system I designed,

our client was highly satisfied with our

solution we presented.

There were two sub-systems of the watering system - collection system and irrigation

system. The collection system was designed to have two switches on both inlet and

outlet to control the level of water stored and keep pressure at certain level. The

irrigation system was designed to evenly irrigate the plants.

The foundation was designed to minimize the work needed and also to contain the

planting soil in order to protect surrounding soil from potential contamination. The

material of steal fittings and PVC frames were chosen for easy maintenance and

replacement.

Engineering design skills

• Applied knowledge learned in class and designed watering system and

greenhouse frame structure

• Constructed 3D model for each main components of the design in SolidWorks

to provide visual demonstration to our client

• Drew engineering sketches for communication with engineering professionals

Leadership and teamwork skills

• Kept communication inside the team flow through different channels; Each

channel was selected according to teammates’ responding time

• Managed project team work in time aspect

Hot cells are highly-irradiated that can only

be accessed by a Human Operator (HO)

from outside the cell using a tele-manipulator

system or mobile robots to perform various

tasks in the cells. The hot cells our client

Canadian Nuclear Laboratory has can only

provide HO with limited visual and haptic

feedback. The objective of this project is to

improve visual and haptic feedback without

compromising the dexterity current system

has.The Final Design

Engineering perspective

• Due to radiation environment, components, especially electronics, have higher

rate of failing. The number of components inside hot cells need to be minimized.

• With consideration of sealing and contamination prevention, the system should

be designed for easy maintenance and replacement.

• In order to ensure reliability and safety, the system should be designed to have

redundancy in case of components failure.

Team perspective

• Because of team members coming from different disciplines, the schedules of

each individual are very different. It might be difficult to keep communication

open inside the team as well as between the team and client.

• Because of different backgrounds, each individual in the team does not always

share the same perspective with others, which could cause another

communication problem.

The proposed design was selected from five candidate

designs. The selection process included Weighted

Decision Matrix with each candidate competing with

current system with regarding of the ability of meeting

functions and objectives. Each single score assigned was

discussed and agreed among team members. The

proposed design included a visual system that generates

virtual reality based on information captured by the

cameras and also a haptic feedback system provided

by Haption, a company that specialized in haptic

devices.

Virtual Reality With Markers

The proposed design was then presented to the client

and supervisor for critique. After we had the

permission to move forward, we contacted the

suppliers for both systems for specifications and price

quotes. According to the information gathered from

suppliers, the design was finalized – Haption Virtuose

6D TAO as the haptic feedback system and Diakont

D70 cameras with OpenCV as the visual feedback

system. We addressed questions arose during the

critique and performed cost analysis. After evaluated

the design, future recommendation was provided to

the client.

The Final Design

Camera Set-up Maps for Two Types of Lenses

• Traced back from the sponsor list in a YouTube video came across during research

to the MAT 6D by Haption and developed a candidate design based on it

• Proposed to compete candidate designs against current system to have a clear

standard for teammates when assign scores and generate more reliable result

• Found the mechanism of MAT 6D controller from a research paper which was

found based on a small detail in a conference material by Haption

• Researched and prepared, using knowledge learned from class and outside of

school, for fluent communication with professional engineers in conference call

with suppliers

• Analyzed specifications of camera lenses and visualized the camera view

coverage in camera set-up maps in aiding for client lenses selection

Leadership And Teamwork Skills

• Took the initiative to volunteer as the communicator between team and client

then became team leader after

• Acknowledged each teammate had different schedule and communicated with

them frequently to keep the process of the project smooth

• Understood each teammate’s point of the view to keep everyone at the same

understanding and assigned tasks according to each individual’s background

and personal preference

• Developed different ways of working with each teammate to fuel their motivation

• Stepped back and let the teammates to lead when it came to their area of

specialty

The disposal camera was

a term project I complete

when I was in Simon Fraser

University. It contained 23

parts which need to be

molded individually and

assemble them together in

one assembly document.

It also had an outer case

which can prevent water,

but due to there were too

many curvatures on the

surface of outer case, it

was neglected in the

project. The picture on the

left is a explored view of

the disposal camera.

I came up with the candidate design of 3D

printer based on the target market as home

using. The base plate was designed to move

in z-axis which would save lots of space than

putting it move in xy-plane. The extruder

moved in xy-plane guided and supported by

four guiding pipe. The timing belts and gears

would provide motion transmission.

Based on the draft design, more details and

improvements were added into the design.

The two-nozzle system would increase effective

significantly. The frame rod design allows easy

assemble and disassemble. At the mean time,

it was light weighted and needed less material

while providing required strength. The solid

base plate would reduce vibration and noise.

The set of this Planetary Gear Train was from a

electric screw driver, which required high

torque output. The Planetary Gear Train had

a gear ratio from input to output of 84:1.

I designed the band break located on the

input shaft which had much lower torque.

Also, the band break required much less

space than the other break types.

The Right Angle Gearbox

provided a 90 degree

connection between a

motor and a drive roller.

The gearbox was also

used as a reduction drive

to shift the rotational

speed.

I designed Input/Output Connector to connect

Motor and Drive Roller with the Right Angle

Gearbox. I also designed the Supporting structure

to support the whole system which located at 36

inch from floor. The supporting structure had four

legs which was designed to keep the system stable

while it was running, because the motor may have

certain vibration when it was running.
