The goal of the project is to fix, improve, and redesign a mechanical horse simulator to better suit the needs of the client for teaching people with special needs the proper basics of riding an actual horse.
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 reconsidered for it to not have as much of an impact on the system.
The new design will be based on the old design, and will feature some sort of tubed aluminum, most probably 7075. The purpose of this is that aluminum has an even Axial and Bending strength to weight ratio compared to the wood. This and the final dimensions of the full assembly, which depends on concepts from the other team, will be decided after the initial concept review.
