Product overview
About JAKA π
JAKA π is a child-sized biped humanoid from JAKA Robotics, a Shanghai company established around collaborative robot arms. Chinese press reported its unveiling in late May 2026, shortly before Children's Day, and JAKA published an English introduction the following month. The company positions it for education and research, commercial service, entertainment, and companion or elder-care settings.
JAKA's product page specifies a height of 1.22 m, a weight of 42 kg and 27 active joints: six in each arm, six in each leg, one at the waist and two at the head. It lists a 3 kg payload, 1.8 m/s walking speed, two-hour runtime, a 10 Ah battery and 120 N·m peak joint torque. The controller uses an Intel Core Ultra 7 255H with 64 GB of memory, and JAKA says the integrated platform provides 96 TOPS of computing and EtherCAT real-time control. A head camera supports indoor navigation.
The official page supports consultation and secondary development, but it does not publish a price, shipping date or customer deployment. A third-party catalogue's price and production claims are explicitly unverified. The robot is therefore listed as a prototype rather than a commercial product, with the official consultation form retained as a contact route.
“It can walk, run, and even jump, reaching a top speed of 1.8 m/s.”
