Description

SUMMARY

 

JAKA đťťż (Pi) is a compact 1.22 m humanoid robot developed by JAKA Robotics, designed for education, research, new retail, entertainment, and companion/elderly care.It features 27 degrees of freedom, 120 Nm knee torque, 3 kg arm payload, and JAKA’s Fusion Brain — a dual‑domain compute system separating high‑level AI from low‑level motion control.Pi is one of the smallest fully capable humanoids in its class.
