Crew Trainer

• Design Team, Number 1
• Josh Adams, Eric Aielli, Tony Ham, Austin Nixon,
  Alexander Ruege
• Dr. Starzyk
• September 30, 2004

2
Needs Statement

• Crew coaches have no way of knowing an
  individual rowers current condition and
  performance and the location of the boat.

3
Goal Statement

• Design a system that will allow a coach to
  remotely monitor the condition and the
  performance of a rower and the position of the
  boat.

4
Project Objectives

• Monitor the heart rate of each individual rower.
• Measure the strain exerted by each rower on an
  oar.
• Track the location of the boat using GPS.
• Design a system to collect, store, transmit and
  display all above data.

5
Project Constraints

• Design and build a working system using a budget
  not to exceed 5000.
• Build a scaled down prototype by end of December,
  2004.
• Build a full system by May, 2005.

6
Operational Requirements

• The system shall be used in an eight person crew
  boat.
• The system shall operate continuously during
  practices and competitions.
• The strain gauges shall be placed on each oar.
• The heart rate monitors shall be placed on the
  body of each rower.

7
Technical Performance Requirements

• The heart rate monitors shall measure and
  transmit the heart rate in beats per minute of
  eight individual rowers simultaneously to a
  location no more than 5 meters away on the boat.
• The strain gauges shall measure and transmit the
  strain in foot-pounds on eight oars to a location
  no more than 5 meters away on the boat.
• Heart rate data and strain gauge data shall be
  retransmitted to a location no more than 4 meters
  away off the boat.
• GPS data shall be transmitted to a location no
  more than 6000 meters away.

Subsystem Performance Requirements (5)

• The controller shall have a capacity of 64MB in
  memory.
• The controller shall record for a minimum of 20
  minutes.
• The controller shall take 30 samples of input per
  minute.
• The controller shall format the display using one
  line per rower, eight total.

Subsystem Performance Requirements (12)

• Using GPS the system shall measure and display
  the location of the boat with centimeter
  accuracy.
• Using GPS the system shall measure and display
  the speed of the boat in meters per second.

Proposed Trade Studies

• Examine the benefits of on-boat wireless or wired
  transmission system.
• Examine cost effectiveness and complexity of long
  range GPS transmission using repeaters or high
  powered transmitters.
• Examine trade-offs between cost and time of
  system development using high level commercial
  products or low level basic components.
