Progress update since 10/6/2015
Last week our group had a presentation. The feedback is not that good. Our sub-group has to confirm the design of the bogie and present it later in the second presentation.

Progress update
Since last meeting, our team looked at the small-scale bogie design. The switching mechanism is operated by a servo and piano strings. When we try to move it, the string is not working smoothly. Therefore, we think a more solid connections will have a better performance. Also, we want the bogie design look more alike to the real design. Some modifications will be needed.
I talked about this project with one of my friends during conversations. He told me about some tracking methods that can be implemented. Although our group has already decided which method for this project, I think there are still some more ideas can be tried in the future. One of them is called Triangulation.
The concept of triangulation is to determine the location of a point by measuring angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly. The point can then be fixed as the third point of a triangle with one known side and two known angles. (Wikipedia) This method can let us track the cart when it transmit signals to the two reference points.

Since last week, I have thought about what to deal with the carts. Also we just received the previous year's small scale group materials. I had gone over some of them and had a clearer picture on what they have done. I learned about the materials used to build the cart and started to think how to redesign the whole cart to make the scale model look alike the real one.

After the last meeting in the warehouse, I thought of what I can do in the small-scale model team. I looked at the small-scale bogie on Wednesday and I think it might be possible for us to build the actual bogie design in the small-scale. What I think is to add a servo and link it to the switch gears so that it can demonstrate how the switch gear works. Instead of changing the design, I also thought of the possibilities to add the fail-safe design to the small scale model. Like using brakes and ultrasonic sensors to determine the distance between two cabins and control the brake.

Chin Man Bryan Ho
Bryan is a senior BSME student in San Jose State University with a concentration on Mechatronics. He is interested in big community projects like Spartan Superway. As an international student from Hong Kong, he see many improvements needed in current public transportation system in California. In this project, he hope to contribute to show the whole design of the bogie in the small scale model. He enjoys playing computer games and sports.
