RoboKind Zeno R25

Zeno R25 is an expressive humanoid from RoboKind, a Dallas, Texas company. The robot was built for classroom and therapy use. ASME described it as a 22-inch, 10-pound robot that can walk and grasp objects, and the Science Museum Group lists one unit at 4.5 kg.

A published study documents 21 degrees of freedom: seven in the head, ten in the arms, one in the waist and three in the legs. Historical marketing coverage divided the joints differently, so the research-paper total is used here. The face can be programmed to show 32 expressions, and a 240 x 320 resistive touch screen sits on the chest. Listed sensors include a camera in the right eye, eight microphones, infrared distance sensors, a compass, a gyroscope, an accelerometer and nine touch-sensitive body areas. RoboKind's support documentation gives a typical battery runtime of 30 to 60 minutes.

RoboKind launched a Kickstarter for the R25 in October 2013 with a $2,699 minimum pledge against a $50,000 goal, and expected a retail price of about $2,700. The current RoboKind site no longer lists the Zeno-branded model, so it is marked discontinued. RoboKind's warranty page refers to remaining R25 hardware only while supplies last, which may cover later education variants rather than this Zeno release.
