Phase 0: Planning
Mission Statement
Product Description
The product is a data recorder which will be used to determine the speed and acceleration of a forklift truck
Key Business Goals The primary business goals of this product are to
document performance of test vehicles and verify performance of production vehicles,
provide a more useful and ergonomic tool than what is currently used
Primary Market
The primary market for this project is Raymond Corp
Secondary Market
Secondary markets for the data recorder could include any industry requiring low speed data recording.
Stakeholders
Stakeholders in the design of our product include the following:
Raymond Corp.
RIT faculty, staff and students
EDGE™
Phase 0: Planning
Staffing Requirements
Mechanical Engineers
2 or 3
Since the design will probably be mechanical in nature, there will be a strong need for Mechanical
Engineering students. These students will take on the tasks of designing the mechanical system to
acquire data and doing necessary analysis on the design such as stress and fatigue.
Electrical Engineers
2 to 4
There will be a strong need for Electrical Engineering students. These students will be involved
with the data recording system including circuit design and data analysis and transfer.
Industrial and Systems Engineers
0 to 1
An Industrial Engineering student would help to integrate the products from the other disciplines
together and develop procedures for how the final product will be used for testing and
benchmarking.
Computer Engineers
0
Computer Engineering students will not be necessary for this project.
Business Majors
0
Business majors will not be necessary for this project.

Phase 0: Planning
Resource Requirements
People
Michael Skube, Jonathan Bawas - RIT students helping out as contacts with the
company but will not be on the SD team(s)
Team Guide(s) (EE dept. – TBD)
Raymond Corp.
- Analysis and Test Manager: Shane Storman
- Engineer: Gabe Clune [Developed Current 5th wheel]
- Engineer: Keith Galbraith [explored other 5th wheel designs]
Environment
Dedicated working space here at RIT.
Raymond Corp has offered the possibility testing on forklift(s)
Equipment
Computers
Basic Hand Tools
Oscilloscope / Multimeter
Materials
Unknown at this time, materials will be more defined with the needs assessment is
refined.
There are not any materials with long lead times anticipated with this project.
Raymond Corp. has sheet metal manufacturing facilities

Phase 1: Concept Development
Identify Customer Needs - Interviews
Primary Customer(s)
We have had a brief discussion with Michael Skube about the
needs for the project. On Friday 10/12 we had a teleconference
with a group of Raymond Employees involved with use of the
device. This helped to define the needs more closely and find
out background information about what alternative technologies
have involved. The conversation was taped for future reference.
Other Stakeholder(s)
We still need to interview faculty members to confirm our faculty
guides and consultants and to discuss what students from their
department would be able to bring to the project.
Past Senior Design Team(s)
There were not any closely related SD projects.
EDGE™
Phase 1: Concept Development
Identify Customer Needs - Benchmarking
Competitive or Cooperative Solutions
Existing Technologies:
Rolling Wheel
Laser Measuring Devices
Radar Measuring Devices
Data Recording Technologies
Internet Search
Identify sources of radar/Laser technologies for
comparison/evaluation
Technical Literature Search
Research recent advancements in existing technologies
EDGE™
Phase 1: Concept Development
Identify Customer Needs - Benchmarking
•
Previous designs and attempts at measurement devices
– Previous project at BU to calculate speed based on pixels from a stationary camera mounted
on the test area ceiling
– Optical sensors
• Doesn’t obstruct movement – Non Contact
• Previous technologies limited by sensitivity to height above the floor 8-24 in.
• Very sensitive to fluorescent light in lab
– Doppler Radar sensors
• Cost is drawback
• Doesn’t obstruct movement – Non Contact
• Previous technologies limited by sensitivity to height above the floor 8-24 in.
– Laser sensor
• Stationary that points at lift to measure distance
• Lift has to drove in straight line which is sometimes hard to accomplish
• Used for measuring lift velocity now
– Wheels
• Currently used
• Do not go around corners
• Hang off 18 in. - 2 ft
• Measure Tach-gen Voltage
• Long setup time
EDGE™
Phase 1: Concept Development
Identify Customer Needs - Interpret
Needs Statements:
1.
The recorder must acquire (and store) data which can be used to determine
velocity and acceleration.
2. The recorder will be effective within a range of 0-15 MPH with an accuracy of
+/-0.10 MPH
3. The recorder must contain its own power supply.
4. The recorder will operate at 100hz or greater.
5. The recorder will not hinder lift truck maneuverability during testing and
benchmarking.
6. The recorder will be usable on Raymond’s and competitor’s lift trucks.
7. The recorder will interface with a Sony EC 204 data recorder or record a
spreadsheet/text file.
8. The output voltage will match the speed of the vehicle, 1V = 1Mph, or a real time
display of speed/acceleration will be provided
9. The recorder will not require ground contact or will not need adjustment while
lift truck is turning.
10. The mounting and set up time of the recorder will be less than 10 minutes

Areas of Risk and Concern
• The co-op students that were previously going to
be involved have notified us that they will not be
working on the SD team(s).
• The budget and funding is still in question.
• We need to figure out what kind of confidentiality
agreement we need to have with Raymond.
• The differences between what each of the two
teams will be doing has yet to be defined.

Future Plan
Where do you go from here?
Moving Forward:
- Provide Raymond Corp with
a proposed functional
specification list
- We will be receiving
pictures and drawings of
current design
- Define roles of the two
different teams
- Recruit people identified as
possible guides
