Hair robot for natrual 4c hair

PalmTwist AI-Controlled Robotic Loc Retwist Digital Twin PalmTwist is a real-time robotic digital twin that simulates precision cosmetic manipulation — specifically the palm-twisting of natural locs — using a 6-axis articulated robotic arm and a real-time inverse kinematics control system. This project demonstrates how robotics, simulation, and intelligent control systems can be applied to delicate, high-precision personal care tasks. Core Concept PalmTwist models a Perception–Planning–Control loop inside a browser-based 3D simulation: Perception The system detects loc root targets using spatial raycasting within the digital twin environment. Planning A real-time analytic inverse kinematics (IK) solver calculates optimal joint angles for a 6-DOF articulated robotic arm to reach the selected loc root. Control A smoothed trajectory controller moves the robot autonomously into position, applying controlled torque and tension to simulate palm twisting. 🤖 Robotic System Robot Type: 6-Axis Articulated Arm Motion Solver: Real-Time Analytic IK + Trajectory Smoothing End Effector: Compliant Two-Finger Precision Gripper Control Loop: 60 Hz Closed-Loop Controller Telemetry: Joint angles, torque, end-effector speed, contact force
