Vehicle Position Sensing Team Week 9/7/2016 – 9/14/2016

This week, our team has talked to Dr. Furman about the feasibility of using Hall or GMR sensors and corrugated ferrous strip to build the position sensing system. Dr. Furman has introduced the Hall Effect sensors and his idea about accurate position sensing system for the 1/12 scale model. After the discussion with Dr. Furman, our team listed out some difficulties and key parts of our plan.

1. The team has to test if the sensors are able to detect the ferrous strip and give correct feedbacks as we expected. And the test will be done using a large scale ferrous strip and sensor.
2. If the idea work, the team should figure out the size of the ferrous strips in order to achieve a high resolution sensor feedback.
3. There is limiting space between the vehicle and the track, the team have to figure out a way to attach the ferrous strip and the sensors on the track and the car.
4. The team must find the manufacturers which are able to provide us assistance on manufacturing high quality ferrous strips, otherwise we have to make it ourselves.

In conclusion, Dr. Furman provided plenty of useful information for our team, and the team has start working on the testing of sensors.
