Classroom Activity
In the Right Place
Feedback and Control Systems


  • use specified design criteria to compare and contrast four proposed software solutions for a control problem.
  • describe the advantages and disadvantages of control solutions that use an open-loop system (without feedback) and alternative closed-loop systems (with feedback).
  • apply concepts of position, distance, direction, and speed in the solution of a realistically complex problem.
  • interpret graphical data and formulate a recommendation

The activity uses the SAM Robot and a motion detector with the LabPro or the original CBL. (Since this activity requires 2 digital ports, it does not work with the CBL2.)
