What will it do?

The robot you are designing will be responsible for transporting the components and tools needed for classes from the laboratory to the classroom autonomously. It will be equipped with line follower sensors for navigation, 24V 5A motors for movement, two 12V batteries for power, a self-designed and SMD-soldered electronic board, and a Bluetooth module for communication.

Who's done what beforehand?

While reviewing the documentation of past projects, I found a few that could serve as a reference for me:

Andrés Moreno's project, "Fab2D2," is a differential robot designed to assist in moving small objects within a laboratory. The robot incorporates a line follower sensing system for autonomous movement and can carry a maximum of 10 lbs. Whenever the robot moves, it emits a warning sound.The robot operates in two modes: firstly, the "AUTONOMOUS MODE" where it follows a black line. When the robot encounters a cross, it stops for five seconds, allowing people to place or remove objects. You can find more information about this well-documented project, which serves as a guide, at the following link

It's a project that provides valuable insights, although there are differences between it and mine. My robot will have larger dimensions and weight, requiring a more robust design and more powerful motors.

What will you design?

I will design a chassis using aluminum profiles that will be joined using 3D printing to provide strength and support to the robot. On top of the chassis, I will place an MDF furniture with compartments, cut using CNC, to store the components and tools, also I will design the embedded board in eagle.

What materials and components will be used?

The materials and components needed for your project include:

• Aluminum profiles.
• ABS for the 3D printed components.
• CNC-cut MDF for the furniture with compartments.
• Line follower sensors.
• 24V 5A motors.
• 12V batteries.
• Drivers.
• Self-designed and SMD-soldered electronic board (including SMD components).
• Bluetooth module for communication.
• Nuts and screws.

Where will they come from?

The ABS filament, MDF, and electronic components needed to fabricate the embedded board will be provided by the LAB. The aluminum profiles and batteries can be sourced from specialized suppliers in electronics, robotics, and industrial supplies.

How much will they cost?

The cost of materials and components may vary depending on the location and specific suppliers. I would recommend researching prices from different sources to get an accurate estimation. The next image show the price of the materials and components in Peru:

Here is the cost of the materials:

What parts and systems will be made?

In my project, i will manufacture the self-designed and SMD-soldered electronic board. You will also 3D print the necessary parts to join the aluminum profiles and hold the sensors.

• SMD board
• Robot chassis
• MDF structure
• 3D printed parts needed for the assembly

What processes will be used?

The processes involved will include:

• Computer controlled cutting: drawers made of 9mm MDF
• Electronic production: The board will be designed using an Atmega 328 becasuse it has the enough pin for my project.
• 3D printing: a swivel caster wheel support, sensor support and joints.
• Embedded programming
• Networking and communications
• Interface and application programming

What questions need to be answered?

• How to you optimize the programming of the line follower sensors for efficient autonomous navigation?
• How to establish communication and remote control through the Bluetooth module?
• How will I ensure stability and strength of the robot using the 3D printed parts to join the aluminum profiles?
• What batteries should I use?

How will it be evaluated?

the most important is if the robot manages to go from point A to B following the line carrying the components. Then we can include the performance of autonomous navigation and the ability to safely transport components and tools.
