Little Casper has been designed to make sick children smile.
He sees and talks; he walks and plays -avoiding obstacles.
He is currently under test at this cancer hospital in Portugal.
Developers hope Casper will trigger positive emotions in young cancer patients.
100 children contributed to its design.
Companion robots are shaping current research in robotics.
And social acceptance is still the main challenge these robots must overcome.
Casper has already been adopted by both patients and staff at this hospital.
Good job, Casper!
