Robotics Hand for Industrial Automation
Servo-driven robotic hand prototype for basic pick-and-place and industrial automation demonstrations.
Overview
This project explores a robotic hand mechanism for simple industrial handling tasks. Multiple servo-actuated joints provide grasping and release motion, while the controller sequences finger positions for pick-and-place style demonstrations. It is a learning platform for actuator coordination, mechanical linkage design, and repeatable robotic motion.

Architecture
Controller outputs PWM signals to each servo. Motion presets define grip poses and timing for automated handling.

Implementation details
Firmware
Firmware maps control commands into servo angles, sequences grasp/release motion, and can be extended for preset gestures or sensor feedback.
Power
Servo motors are powered separately from logic to avoid brownouts during simultaneous movement.
Components / BOM
Arduino controller, Servo motors, Mechanical frame/linkages, External servo supply
Engineering challenges
Coordinating multiple servos without jitter or power dips was the main prototype concern.
Solutions
Used separate power and sequenced motion to keep the mechanism stable during demonstrations.
Results & metrics
Demo videos show the robotic hand moving through controlled actuation sequences.
Future improvements
Add force feedback, better gripper geometry, inverse kinematics, and ROS/PLC integration.
