VAALI Robotic Hand DIY Kit (Black) – Plastic, Assembled with Software | 5-Finger Design, Programmable Servo Control | Ideal for STEM & Hobby Projects

描述

The VAALI Robotic Hand DIY Kit is a high-quality, black plastic robotic hand tailored for enthusiasts, educators, and developers. Fully assembled for quick deployment, this model features five articulated fingers powered by servo motors and is driven by an onboard microcontroller. It includes built-in software support for programming gestures, motion routines, and real-time control. The robust design is ideal for classroom demonstrations, robotics competitions, or R&D prototyping. This robotic hand serves as a valuable educational tool for learning motion control, programming logic, and mechanical articulation. Whether you're a student exploring robotics or a professional building an intelligent automation system, this DIY kit offers expandability, ease of use, and a realistic approach to human-like dexterity. Start innovating with the future of robotics – hands-on. A robotic hand converts human motions into mechanical movements by combining precise hardware and clever software. The hardware consists of high-torque servos (MG996R) for stronger joints and micro servos (SG90/XSG90) for finer movements. It is all coordinated by an ESP8266 microcontroller that runs PWM control routines and a bespoke PCB, and it is fuelled by a steady 5 V supply. An ESP8266-hosted web server (using HTTP or WebSocket protocols) receives these commands and actuates the servos in real time. The software stack consists of an OpenCV-based hand-recognition and pattern-matching program (often leveraging Mediapipe or keypoint descriptors) that runs on a PC to interpret gestures and map them to specific finger positions. These parts work together to provide a closed loop that allows for responsive, web-accessible control of the robotic hand. This loop includes camera acquisition, gesture analysis, network transmission of orders, and precise servo positioning. Review: Overall average - Non assembled parts given even strings were not provided for tendon quality is good but not value for money as in 1.8k one expects it to be assembled atleast the strings and wires Review: good kit - great kit . I have submitted in my final year college project .
