Beijing Smart Technology’s Service Robots

A Chinese robotics distributor called Beijing Smart Technology has developed their own line of humanoid service robots.  The company’s most recent offering is a general-purpose service robot called ZNJ-SW01.  The company says the robot can be rented to serve as an entertainment robot, a guide at museums and art galleries, or as a research platform for universities.

Like many service robots currently being developed, the robot moves on wheels with a humanoid upper body.  It automatically detects when someone approaches, and if a person stands in front of it for a few seconds, the robot extends its arm to shake hands and says, “Hello, I’m glad to see you!  Can I help you with anything?”  When they walk away more than 1.5 meters, it waves good-bye and tells them to “come again”.

Besides simple conversations it can play quiz games.  It can index more than 100 people using its camera, and remembers them with more than 50% accuracy.  That may not sound all that impressive, but you have to factor in a small sample of training images, and changing lighting conditions.  A touch screen displays relevant information or endorsements.  All of its speech recognition and other functions are processed on an embedded PC.

It stands 165cm (5’5″) tall and weighs more than 50kg (110 lbs).  It can nod and shake its head, and twist at the waist.  Each arm has 5 degrees of freedom, allowing it to perform common gestures like waving and shaking hands, and its three fingers can hold small objects.  It comes equipped with infrared sensors, ultrasonic range finders, wheel encoders, and other sensors to achieve autonomous navigation (accurate to within 20cm) and obstacle avoidance (2 meter radius).

Beijing Smart Technology has previously developed a more feminine robot called Mary (above photo) with Peking University.  Watch a video of some lab tests after the break.

    At this rate there won’t be any museum guide jobs left for humans. At least we will still have jobs dealing with old people and nuclear waste.
