S21-Group12-Fancy Horse


The goal of this project is to fix, improve, and redesign a mechanical horse simulator for Manna’s Hana Riding Center in Cookeville, TN to better suit the needs of the client for teaching people with special needs the proper basics of riding an actual horse.

Problem Statement

As stated on their website, “Manna’s HANA is a nonprofit corporation founded through love to provide recreational riding for individuals with special needs by means of equine-assisted activities.”  Manna’s Hana Riding Center has already received a mechanical horse from Tennessee Tech, but has found some issues with it.  The biggest issue is that it is too big for many of the kids to properly straddle.  There is also an issue with the fact that the mechanical horse had been broken once before because of the insufficient weight limit.  This has led to the client asking for us to design a horse that can handle more weight.  Reigns were installed on the horse as well that would light up yellow for left or right steering, and red for braking.  These were not properly installed in the first iteration, and as a result, this feature does not work.  The movement also needs to be fixed, as the client does not feel that it moves quite like a horse should, and there is a bit of rubbing of materials.  The head is also a little on the heavier side, so the means of attachment needs to be reconsidered for it to not have as much of an impact on the system.

Design Specifications

  • The customer wants to redesign the body of the mechanical horse to fit a smaller 30 gallon barrel vs 50 gallon barrel to allow smaller children to ride it
  • Improve weight capacity from 160 lbs to 180 lbs
  • More realistic movement of the mechanical horse in X, Y, and Z directions
  • A more responsive and reliable electrical response system for the reigns with increased sensitivity of LED steering application for better learning technique
  • For extra improvements, an aid in helping learn how to properly post in a saddle is being considered.
