Meeting with Your TA

Description

By the Thursday of the third week, you must have a project approved, and should be ready to get working! At this time, you'll need to log into PACE and submit your schedule for the semester. Please be sure to make this as accurate as possible because once it's submitted, it can only be changed manually. Making a block of your schedule red means that you are unavailable during that time.

Once each person on your team has submitted their schedule, your TA will be able to easily check for available times to schedule a weekly meeting. Your TA should contact you, usually by the fourth week, via email, to set up a weekly meeting schedule at mutual convenience. During the first weekly meeting, your TA will assign your team a locker and a lab kit.

Weekly meetings with your TA are required and will be held throughout the entire semester until demonstrations are completed. Your TA is your project manager. The "homework" of the course consists of preparing for the weekly meetings. Your TA will evaluate your lab notebook each week, provide feedback, and recommend improvements. At each meeting you will be expected to present your progress since your last meeting, plans for the coming week, and any technical or administrative questions you need to discuss with your TA. You are expected to arrive on time and prepared to make good use of your time with your TA. Your TA may require that each team member to fill out the Progress Report Template and submit it to them prior to each weekly meeting.

Requirements and Grading

Attendance and participation in weekly meetings is required and will affect Teamwork and Lab Notebook scores. If you can't make it to a particular weekly meeting, it is your responsibility to inform your TA prior to the meeting time and set up an alternate time.

Submission and Deadlines

Your schedule must be submitted by the end of the third week of class and you will receive an email from your TA shortly after. Your first meeting with your TA should be during the fourth week of the semester.

Electronic Automatic Transmission for Bicycle

Sometimes bikers might not which gear is the optimal one to select. Bicycle changes gears by pulling or releasing a steel cable mechanically. We could potentially automate gear changing by hooking up a servo motor to the gear cable. We could calculate the optimal gear under current condition by using several sensors: two hall effect sensors, one sensing cadence from the paddle and the other one sensing the overall speed from the wheel, we could also use pressure sensors on the paddle to determine how hard the biker is paddling. With these sensors, it would be sufficient enough for use detect different terrains since the biker tend to go slower and pedal slower for uphill or go faster and pedal faster for downhill. With all these information from the sensors, we could definitely find out the optimal gear electronically. We plan to take care of the shifting of rear derailleur, if we have more time we may consider modifying the front as well.

Besides shifting automatically, we plan to add a manual mode to our project as well. With manual mode activated, the rider could override the automatic system and select the gear on its own.

We found out another group did electronic bicycle shifting in Spring 2016, but they didn't have a automatic function and didn't have the sensor set-up like ours. Commercially, both SRAM and SHIMANO have electronic shifting products, but these products integrate the servo motor inside the derailleurs, and they have a price tag over $1000. Only professionals or rich enthusiasts can have a hand on them. As our system could potentially serve as an add-on device to all bicycles with gears, it would be much cheaper.
