Brussels Anty Foundation, which works to improve the experiences of kids in hospitals, came to the university a few years ago with a proposal to create a robot that could comfort children by understanding their emotional and physical traumas and even explain medical procedures to them. Probo is equipped with cameras in his eyes and with audio programmes, so it can actually assess a child’s emotions. “Vision analysis is used to recognise facial expressions and then translate those into emotions,” explains Jelle Saldien, an engineer working on the project. “Audio analysis can identify the intensity and pitch of a child’s speech. If you combine the two, you have some idea of the emotional state – if a child is calm or angry.” Probo will also be able to respond to children appropriately with its own facial expressions and speech that correspond to happiness, sadness or confusion. “There are no real words, so it’s not really a language,” says Saldien. “But it can communicate emotions with sounds – like the Teletubbies do.” Through the use of artificial intelligence, programmers can actually train the robot to improve its recognition and response skills. Speaking of Teletubbies, the Brussels’ robot will also be fitted with a screen in its stomach to show children videos explaining medical procedures they will undergo and “which crazy, scary machines they will see,” says Saldien. “The robot can prepare the children so we can reduce their fear before medical examinations.” Kids will also be able to play computer games on Probo, and older kids can surf the internet. Eventually, you could have a Probo sit in a classroom and focus on the teacher and the blackboard and relay the images to the child in the hospital, so he or she could continue with school. But can an expensive robot really perform services that medical staff can’t? “You have to give children information in a special way,” explains Saldien. “When they are really young, they are living in a fantasy world. You have to sustain that world, even when they are in the hospital. Otherwise, it can be really traumatic for them.” Hence Probo’s look and feel. To children, he is a big stuffed toy. The name is derived from the Latin proboscidea, a zoological order that includes a number of extinct species and now includes only elephants. Of course, “robo” refers to its own modern species, making Probo a mix of an ancient past and a technological future. Kids get a kick out of such a fantastical creature. Currently, robotics are being employed in other parts of the world to perform tests, particularly with autistic children. Probo is only one of two in the world, though, that is “huggable” – Japan has a baby seal version they are using with children and the elderly. The ultimate goal is to have Probos scattered throughout hospitals in Belgium. But only one is expected to be serviceable this year. “Then we need to build more prototypes and do a lot of testing and see what is working, what isn’t, what could be improved,” says Saldien. “The vision and audio software will be upgraded gradually, so the robot becomes more and more autonomous. But for now, the main aspect is really just safe interaction.” Online [url=http://anty.vub.ac.be/info/Probo]http://anty.vub.ac.be/info/Probo[/url]
