Update: Final Presentation
Jog Mode
Acceleration can be shown by the increase in amps, which is displayed on the generator.
Block Diagram of Final Project Overview
Update: Week 9
- Even though the gearing system has been running smoothly, we decided to design a whole new gear design to add more torque
- At the moment, it takes the max speed just to get the wheel to spin, and we have to gradually decrease the speed to start running the program, it's a complication we are trying to fix
- That involves a new construction of the gear holding system!
- Added a new "setting" to the program, just a standard walking pace
- Made touch-ups on previous "settings" to fix any flaws or sources of complications
[Figure Above: Taking apart the previous gearing system]
[Picture Above: Getting help from the TA]
Update: Week 8
Design new support for gears. Goal to increase torque by 6x using NXT gears.
Improve program to take in input for male/female jog or sprint
Improve the error tolerance so bad input will be rejected
More speeds variation in program
The motor gear system is successful.
[Halvor describing the Motor-Bee Wiring]
[First successful run of gears and motor base]
Update: Week 7
Test motor run through laptop: success
Hamster and gear run: failure
Not enough torque, need to design new gear placement system
Needed to go to woodshop to recut Motor-Base

Update: Week 6
Difficulties:
- Plugging in the equation into C++
- Attaching the motor into the wood base
- Drawing/calculating equations to give to the wood shop to have them cut it for us
- Using the Motor-Bee CD while running LinuxMint
Update: Week 5
- Now that we have a motor, we have to come up with a plan to secure the hamster wheel and the motor
- Construction of a base board, and potential motor wood-stand
- Independent research on C++ and MotorBee
- Unable to move forward in this project until we learn the programs!
Update: Week 4
Jithin and Halvor went to Radio Shack to purchase a motor. Purchased 1.5 - 3V Electric Motor. $5.00
Purchased saudering iron and wiring $15.00
Designed wooden base support for hamster wheel and sent to wood shop.
Update: Week 3
Ordered 8-Inch Hamster Wheel from Amazon $10
Researched Optimal Heart Rate:
Men:
Min: (220-age)*0.5
Max: (220-age)*0.85
Women:
Min: (226-age)*0.5
Max: (226-age)*0.85 error could be 15 beats higher or lower
Method 2
1. 220-age= Max heart rate
2. Max Heart rate - resting heart rate= HRreserve
3. 0.6*HRreserve+resting heart rate=min heart range
4. 0.8*HRreserve+resting heart rate= max heart range
5. (Min heart range+max heart range)/2=optimal heart beat
Website Link to calculate heart rate
Plan of Project:
Plan to gradually increase speed to reach the interval. If increase speed gradually, the heart can adjust to it. Then gradually decrease speed when reach the min value because the heart will keep working hard because the person running will be getting tired. Point to PROVE the concept.

Update Week 2
Basic diagram and updates!
After hours of research, and comments from Reddit computer experts, we have decided to use a Motor-Bee and a motor instead of Raspberry Pi.
The most challenging aspect was finding a place to purchase Motor-Bee. We finally managed to find a place, even though the price was in Euros...
We even found a site that provided us with a pdf Motor Bee Manual.
Update plan:
- Use motor bee to run a motor that will be programmed with a powerful laptop/PC
- Program written in C++ or C
