Seeed Studio Amazing Hand — 8-DOF Open-Source Robotic Hand Kit with Feetech Servos (Right / Left)

A four-finger robotic hand developed by Pollen Robotics as an open-source design, sold as a build-it-yourself kit. Each finger has two phalanges driven by two small serial bus servos in a parallel mechanism, so the hand can both bend and spread its fingers. The rigid parts are 3D-printable and covered by flexible shells, which makes it practical for grasping experiments, teleoperation and imitation-learning projects, for example mounted on a robot arm. The included driver board is made for a Seeed Studio XIAO; it can also be controlled from a Raspberry Pi, NVIDIA Jetson or another microcontroller over UART.
