Description

This repository contains the Bill of Materials (BOM) for the RIO robot hardware parts and assembly. The RIO project aims to transform your smartphone into a fully-featured ROS2 robot, utilizing a wide array of built-in mobile sensors and custom hardware. The hardware design includes a custom PCB, motor drivers, and sensor integrations that work seamlessly with the RIO mobile app and ROS2 ecosystem.

Fabrication Options

The RIO robot chassis can be fabricated using either full 3D printing or a hybrid approach combining laser cutting and 3D printing. Here are the details for both options:

Option 1: Full 3D Printing

All parts are available as STL files in the 3dPrinting folder:

Base Components:

• base_bottom.stl - Bottom plate of the chassis.
• base_top.stl - Top plate of chasis.
• motor_bracket_left.stl & motor_bracket_right.stl - Motor mounting brackets.

Mobile Phone Mount:

• mobile_holder_base_top.stl - Top connecting piece
• mobile_holder_base_side_left.stl & mobile_holder_base_side_right.stl - Mount side connecting side pieces
• mobile_holder_top_bracket_left.stl & mobile_holder_top_bracket_right.stl - Top connecting brackets
• mobile_holder_bracket_left.stl & mobile_holder_bracket_right.stl - Mounting brackets holder to chasis

LED Holders:

• ws2812b_holder_left.stl & ws2812b_holder_right.stl - RGB LED mounting brackets

Option 2: Hybrid (Recommended)

For better durability and professional finish, you can use a combination of laser cutting and 3D printing:

Laser Cut Parts & Files:

• Base Components (3mm Acrylic):

  • base_bottom_3mm.dxf - Bottom plate of the chassis
  • base_top_3mm.dxf - Top plate of the chassis

• Mobile Phone Mount (5mm Acrylic):

  • mobile_base_top_5mm.dxf - Top piece
  • mobile_base_side_left_5mm.dxf - Left side piece
  • mobile_base_side_right_5mm.dxf - Right side piece

• Complete Design File:

  • all_files_laser_cutting.cdr - CorelDRAW-v11 format with all components

3D Printed Parts:

• Motor Mounts:

  • motor_bracket_left.stl - Left motor bracket
  • motor_bracket_right.stl - Right motor bracket

• Mobile Phone Mount Brackets:

  • mobile_holder_bracket_left.stl - Left mounting bracket
  • mobile_holder_bracket_right.stl - Right mounting bracket
  • mobile_holder_top_bracket_left.stl - Left top bracket
  • mobile_holder_top_bracket_right.stl - Right top bracket

• LED Holders:

  • ws2812b_holder_left.stl & ws2812b_holder_right.stl - RGB LED mounting brackets

Note: The hybrid approach (Option 2) is recommended for better durability and professional appearance. However, full 3D printing is perfectly viable for prototyping or if laser cutting is not available.
