Project Summary: To design an apparatus that will be used to present three-dimensional objects to a beluga whale in a match-to-sample (MTS) procedure. In the MTS procedure, a sample object is shown to the whale (e.g., a sphere), then the sample object is removed, and finally three choice objects are presented to the whale (e.g., sphere, cylinder, cube). The whale's task is to select the choice object that matches the sample.

Beluga Whale Echolocation• Details: The animal emits loud, high frequency sounds that bounce

off of objects in its environment and return echoes to the animal's ears. The echoes carry information about the size, shape, material, and structure of objects. • Uses: Detect predators, locate prey, navigation

Project Tasks: • Create a functioning MTS apparatus.•Design and build two sets of 42 objects consisting of different sizes, shapes and materials.•Develop a user’s manual for the MTS apparatus.•Design a testing protocol for the step-by-step process of using the MTS apparatus.

Final CAD Design

When the mechanism is released, the

objects are lowered into the water and presented to the

whale.
