Animals on the Grid

Animals in Africa face challenges from dwindling habitats and climate, but most dangerous of all can be farmers or poachers who can kill threatened species for protection and profit. Watch how researchers at the North Carolina Zoo are using radio and satellite tracking to follow and protect animals in Africa and in our own backyard.


Mechatronics blends principles of design and engineering to create the most innovative, economical, appropriate and elegant solutions to engineering problems. Watch engineers and students from NC State University and UNC Asheville put mechatronics into action.
