Otto Trailer / Wagon

This trailer is a versatile expansion for the Otto DIY robot, offering extra storage and power options. It is designed with modularity and functionality in mind.

Key Features:

  • Smart Power Management: The bottom section features a dedicated slot for an Otto battery. You can use it as storage for a spare battery or to power your own add-ons and electronics within the trailer.

  • Cable Routing: Small routing holes are located in both the upper and lower sections, allowing for clean cable management between components.

  • Modular Design: The trailer consists of two parts. You can use the bottom section on its own or attach the upper part whenever needed.

  • High Versatility: Equipped with multiple mounting points, offering endless possibilities for customization and attachments.

🛠 Assembly Recommendations:

  • Wheel Axle: While a 3D-printable axle is included in the design, I highly recommend using a metal M3 rod instead. This provides significantly better durability and smoother movement.

  • Feedback Welcome: I appreciate every comment regarding potential flaws or ideas for improvement.

Enjoy your Otto and its brand-new trailer!
