Overview
The ORCA Hand has five digits and 17 fully independent degrees of freedom driven by 16 finger actuators plus one wrist actuator (Dynamixel XC330-T288 or Feetech HL-2915 class), tendon-driven, weighing 1.1 kg with ISO 9409-1 mounting and orca_core firmware. The Touch variant integrates custom Hall-effect fingertip sensors delivering 6D force/torque per taxel across 351 taxels and weighs about 1.25 kg; a 9-DoF lite model uses coupled tendons and is self-build only (BOM under $900).
The design is open source — BOM, CAD files, and assembly video are published — while assembled hands sell from $3,500 (Feetech) or $4,500 (Dynamixel) and the Touch from $6,100 or $7,100, with add-ons such as joint position sensing and a spares kit. ORCA Dexterity, Inc. is a Delaware corporation with its team based in Zurich; the v1 hand is documented in arXiv:2504.04259 (2025).
