In the spring of 2012, Grady Hofmann was told he needed a bone marrow transplant, and that afterwards he would be confined to a small isolation room in a hospital.

Friends of the family convinced a Silicon Valley firm to loan one of its telepresence robots. The robot, dubbed GradyBot by the family, was the patient's eyes and ears to the outside world for two months, taking part in pre-bedtime chat, visiting school, celebrating birthdays and even enduring the usual sibling torment.

Click's Sumi Das reports on how the robot helped Hoffmann live his life at home and in the classroom while being confined to a hospital bed.
