CAD bone prototype

The proposed experimental designs below will function as the framework for the testing or the load bearing potential of the prototype "Inflatable bones", as well as testing prototypes for additional characteristics.

Load Bearing:

This experiment will involve inflating the prototype to various pressures within the project engineering requirement limits. Load will then be added onto the prototype and increased until the bone buckles. Maximum load tested may be set to keep the experiment within reasonable loads for the project (i.e. the robot will not likely reach 100 lbs, making this an upper limit of the experiment). Finally, a rig for holding the prototype and the weights would be ideal.

The data gained from this experiment will be used to determine the ideal pressure to inflate the bones to handle the weight of the robot.

Pressure Limits:

This experiment will involve inflating the prototype until failure due to pressure, or until an upper limit is reached. A proposed pressure limit would be 100 psi, which is 25% greater than the engineering requirement limit.

The data gained from this experiment will be used to determine the maximum safe pressure that the prototype bones can be inflated to. Additionally, it may identify functional shortcomings with the prototype such as material, or the adhesive used.
