A robot named Cosmo has become six-year-old Kevin Fitzgerald's aid in his uphill everyday battle with development difficulties.

Kevin showed the first sign of learning difficulties when he was 18 months old, and was later diagnosed（诊断） with developmental disorder. But for the past year, a small blue-and-yellow human-like computer called Cosmo has offered some hope.

By responding to body movements and voices, Cosmo is designed to teach basic behavioral and physical skills. It can use its hands, repeat phrases and walk around. Mostly, it serves like a toy, a friend and a teacher cheering, encouraging, and tipping them to complete special tasks.

The robot's inventor, Corinna Lathan, believes "it can greatly improve on traditional and computer-based learning," she said. "The idea is that rather than hiding in front of a computer you are actually starting to communicate with a child the same age and the hope is that it may help transfer to other people—adults, care-givers and parents,"

As a piece of engineering, Cosmo looks rather simple. It has just nine moving joints（关节）. But Cosmo's advantage to help children has caught the attention of Minnesota's world-famous Mayo Clinic.

"It's going quite well," said Krista Coleman-wood, an expert at Mayo's laboratory. "But it is too early to say if children make more progress with the robot than through traditional physical treatment, but fun levels are clearly in the robot's favor."

Mrs. Fitzgerald says the last 12 months' treatment with Cosmo has proven revolutionary.

"When we first started, I could not get him out of the car if he knew it would be something challenging. Now if I mention that Cosmo is going to be here, he just comes running."
