Collection: Robot Hands

Overview

Our robot hand kits feature 5-DOF humanoid finger mechanisms — each finger driven by an independent servo motor for true individual finger control. Available in humanoid (A0090 servo) and educational (MG90S servo) configurations, with both left and right hand options. These kits are used in prosthetics research, sign language robotics, and advanced STEM projects.

How a Robot Hand Kit Works

Each finger in a 5-DOF robot hand is actuated by a single servo motor pulling a fishing-line tendon routed through the finger linkage. When the servo retracts, the finger curls; when it extends, a return spring opens the finger. All five servos are independently controllable from Arduino, allowing individual finger positioning, gesture programming, and gripper patterns. The metal finger links provide rigidity that plastic equivalents cannot match.

Humanoid vs Educational Configuration

• Humanoid hand (A0090): Compact, higher torque, closer to human finger proportions — ideal for research and display projects
• Educational hand (MG90S): Widely available servo replacements, easy to source spares, great for classroom use
• Both: Full 5-DOF independent control, metal construction, Arduino-compatible
• Variant kits: Left hand, right hand, or pair — check product variants
