HP Ott Robot Wheel Set

UPDATE!

Now you can print the rin tyre only and the rim separately and glue it together.

Also there is a leighter (less material) version of the rim.

Now you can print it from diferent materials.

Thanks HP Robots Otto for the idea!

HP Ott Robot Wheel Upgrade – Off-Road & Drag Tires

This project includes two custom wheel types designed for the HP Ott robot as part of a robotics accessory challenge.

The goal was to create wheels optimized for different driving conditions, allowing the robot to perform better depending on the terrain.

Included Wheel Types

1. Off-Road Tire

• Aggressive tread pattern for better grip

• Designed for rough surfaces and obstacles

• Improves traction on uneven terrain

2. Drag Tire

• Smooth slick-style tire

• Optimized for maximum contact surface

• Ideal for speed runs and smooth floors

Both tires are designed to fit the HP Ott robot wheel system and can be easily printed and mounted.

Wheel Rims

The rims used in the preview images are separate models.

Printing Recommendations

• Layer height: 0.2 mm

• Material: PLA / PETG

• Infill: 15–25%

• Supports: Not required

• Orientation: Print flat on the wheel side

For better grip you can also try:

• TPU for flexible tires

• PLA+ for stronger rigid wheels

Compatibility

Designed for:

• HP Ott Robot

Why I Made This

This model was created for a robot accessory design competition, where the goal was to expand the capabilities of the HP Ott robot with useful upgrades.

These wheels allow the robot to adapt to different driving styles: terrain exploration or high-speed runs.
