Pleo was engineered by a group of scientists, biologists, programmers, animators, specialists and technologists. The design combines sensory, articulation, and neuronetics to create lifelike appearance with organic movement and adaptable behavior. It was designed by Caleb Chung, the co-creator of the Furby. It is software-upgradable, and modifications to it’s firmware is also encouraged. There will be an API for programmers called “PDK”.
