n a sunny room at the Boys & Girls
Club in Calistoga, a tiny city in Califor-
nia’s Napa Valley, Veronica Ahumada
is setting up her robot when a be-
spectacled little boy wanders in to ask
what she’s doing. Ahumada points to
the device—basically a tricked-out tab-
let on a meter-tall post, mounted onto
gyroscopic roller wheels—and he yelps
like he’s seen a ghost. “She has a robot!” he
hollers, bolting out the door.
Soon, about 40 tweens fill the room. Many
are Latino like Ahumada, and they are here
for after-school child care while their parents
work. When she invites them to guess what
the robot is for, their ideas bubble over: to
play video games! To go to the supermarket!
To help people get around! To take orders at a
restaurant! To take over the world!
Ahumada, who studies health informatics
and human-robot interactions at the Univer-
sity of California (UC), Davis, acknowledges
each child’s suggestion, then explains: “I use
these robots for children just like you,” but
who can’t go to school because they have
serious illnesses such as cancer or heart
problems. Those children can send the robot
instead, she says, and join their classmates
virtually, from home. The group falls silent.
“Whaaaaat?” they croon in a collective tune
of disbelief.
In fact, rolling robot avatars allow ill chil-
dren to attend school remotely in a few hun-
dred classrooms across the United States and
a smattering of other countries. The gadgets,
called telepresence robots, were designed to
allow doctors to conduct rounds from a dis-
tance and corporate executives to visit remote
facilities. They show a remote user’s face and
let the user see, listen, and speak as if they
were present. Ahumada and a few other re-
searchers think the devices could provide
classroom access to a long-overlooked group
of children. “We’ve never in the history of the
world had the opportunity for children with
these serious medical conditions to go to
school with their peers,” Ahumada says.
Children who use the technology have
called it life-changing because of the social
connections it allows. “It’s like I’m actu-
ally there—that’s why I like it so much,” an
8-year-old told Ahumada. In addition to
taking part in lessons as if they were in the
In a few classrooms, robots attend for children ailing at home.
