For this project, we will construct a “squeeze machine” as a therapy device for children with ASD.
Children with Autism or related disorders seek proprioceptive input. A therapist working with the child wanted a play toy that the child could get full-body proprioceptive input (“Squeezing”) through independent play.
Child size, weight, age.
Overall size of space for toy/machine
Ease of use.
Team has idenitified three related technologies that can be purchased. None meet the need exactly.
The second enghineering analysis considers the loads on the rollers. The primarly loading comes from the weight of the child when going through the toy., Plase ee the see the schematic below. The rollers are treated as simply supported beam and the maximum deflections in each roller are calculated as shown on the document below. Based on this, the maixmum roller deflection os 0.033 inches under expected load conditions (xxx lb child) which is well with in our operating limits.
The team started work on 4/1/2018 and did the majority of the work in the ME shop and at home. The images below document some of the fabrication steps performed by team members.
