Objective:
The objective of the full scale control team is to improve the existing control systems and incorporate a wireless or joystick controller on the bogie. In the summer of 2018, the control team will mainly focus on producing a physical prototype of the linear actuator and incorporate position encoder into the full scale bogie. Other factors for the control team to look at are the required energy for the bogie to move forward, sensing collisions, switching tracks, and steering to avoid stiffness in turns, and programming software to adhere to the design requirements. Also, communication between other project teams is necessary for a successful assembly of the entire full scale project.
Past Work From SJSU Students:
A past senior project on control systems for the Spartan Superway have used an Arduino Mega to control the mechanical behavior of other parts of the system. The project implemented a joystick which would allow the user to control the velocity of the bogie. Ultrasonic sensors were used in the design for the safety of the transportation system. A kill switch was added in order to disconnect a direct current motor in the event of a malfunction. A linear actuator was conceptually proven to perform the track-switching action from when the bogie moves from the main track into the offline station, but the team did not have sufficient time to make a prototype. This project used materials that costed about five hundred dollars total as stated in their bill of materials.
Past Work that can be used:
The linear actuator from the past senior project from SJSU is useful because it will enable the bogies to switch tracks which is vital for consistent traffic flow on the main track. The past project was able to prove conceptually its ability to successfully perform the track switching action and this concept can be used by the current control team to carry out a rapid prototype.
Commercial Products:
Commercial products that may be used are included in this bill of materials, but the Kelly Services Motor Controller may be omitted due to complications in the past. The Altrax 48300 Motor Controller may be used instead for the prototype.
