Build Jary. Modify it. Make it yours. The JARY-Bot is an open-source 15-DOF educational humanoid robot. Download the latest files, 3D-print the chassis in PETG/PLA+/TPU, then assemble it with the matched electronics kit and the included quick-start guide.

  • Open-source 15-DOF chassis

    Download the files and 3D-print the complete structure — pelvis, legs, arms, torso and head — then study, modify and share the geometry freely.

  • Professional electronics kit

    Includes 15 FEETECH ST3215 bus servos, ESP32-S3 controller, OV5640 camera, MPU6050 IMU, servo driver, LiPo battery and protected power management.

  • Guided humanoid build

    The quick-start guide covers printing orientation, wiring the bus servos, IMU calibration and the first walking sequences — no prior humanoid experience needed.
