Development of a Linear Motorized Table for Controls Labs at Vermont Technical College

Vermont Technical College currently lacks a linear motorized table for controls labs, making certain experiments difficult or impossible. Our design solution is to create a custom linear motorized table based on specifications provided by instructor John Murphy. This versatile lab platform will enable us to build a scaled-down crane model for analysis, characterization, and control. The system includes components such as a motor controller, potentiometer for angle measurement, optical sensor for positioning, and an accelerometer for speed measurement, facilitating effective lab activities.

  1. Linear Motorized Table Jean-Carlo McLure, James Hunton

  2. Design Problem Vermont Technical College does not have a linear motorized table for use in controls labs. Due to the college not having this piece of equipment, some of the labs done for the controls class are either very hard to prepare and execute or the labs just can not be done.

  3. Design Solution The solution to this problem is for our group to make our own linear motorized table using specifications given to us by the instructor, John Murphy. Using these specifications, we will characterize create a controller to work with the board.

  4. Design Function The function of this linear motorized table is to be a versatile lab platform. For this project, we are using the table to create a scaled down model of a crane that we can analyze, characterize and control.
