6mm Shaft Dummy Motor wheel For Robotic chassis

6mm Shaft Dummy Motor Wheel For Robotic Chassis is a crucial mechanical component for robotics projects, specifically designed to function as an idler wheel or passive support wheel. Unlike a driven wheel connected directly to a motor, the dummy wheel allows your robotic chassis to maintain stability, balance, and accurate movement across a surface without adding complexity to the drive system. This wheel features a specific 6mm bore, making it perfectly compatible with standard 6mm motor shafts or axles, and it mounts easily to side plates or suspension arms. Robotics developers frequently use these wheels in three-wheel (tricycle) or four-wheel configurations to provide stable rear support or to serve as freely rotating omni-directional points, ensuring smooth, reliable motion for various exploratory and competition-based robots.

Key Features:

• Passive Movement Design: Functions as a stable idler wheel, providing essential support without drawing power or requiring complex motor control.
• Standard 6mm Bore: Features a perfectly sized 6mm center hole for precise, non-slip mounting onto standard D-shafts or keyed 6mm motor axles.
• Durable Construction: Built from robust plastic or rubber materials to handle the weight of the chassis and withstand typical wear and tear on various surfaces.
• High-Traction Tread: The exterior is often equipped with a rubber or silicone tire to maximize grip on floors, mats, and obstacles.
• Lightweight Design: Minimizes overall robot mass, improving motor efficiency and battery life.

Technical Specifications:

• Axle Compatibility: 6 mm Shaft Diameter (D-shaft or standard cylindrical)
• Material (Hub): ABS Plastic, Nylon, or Reinforced Polymer
• Material (Tire): High-Traction Rubber or Silicone
• Operating Speed: Suitable for low to medium-speed robotic applications.

Mechanical Specifications:

• Bearing Type: Friction Fit or Integrated Bushing (allows free rotation on the axle).
• Mounting: Press-fit onto a 6mm axle or secured with a grub screw (set screw).
• Drive Type: Passive/Non-Driven (Idler Wheel).

Dimensions:

• Outer Diameter: Varies, typically 45 mm to 65 mm
• Tire Width: Varies, typically 15 mm to 25 mm
• Shaft Bore Diameter: 6.0 mm

Pinout and Wiring:

• Note: As a purely mechanical component, this dummy wheel does not require electrical power, wiring, or pin connections.
• Installation: Securely fasten the wheel onto a stationary 6mm axle or directly onto the chassis using a bracket and bearing assembly.

Commonly Used in:

• Educational Robotics Kits: Providing stable rear support for beginner platforms.
• Mobile Robot Platforms: Used as caster wheels or omni-wheels in advanced mobile bases.
• Line Following Robots: Ensuring straight and stable movement on the track.

Applications:

• Supporting Weight: Distributing the load of the robot chassis over four or more points.
• Improving Stability: Preventing rocking and tilting motion during acceleration and braking.
• Tri-Wheel Configuration: Serving as the third, stabilizing contact point opposite two drive wheels.

Equivalent Models:

• Omni-Directional Wheels: Used when lateral movement is needed (often with smaller, multiple rollers).
• Caster Wheels: Freely swiveling wheels used primarily for passive, variable direction support.
• 4mm or 5mm Bore Wheels: Alternatives for use with smaller, lower-power DC motors.
