Battle Bots with Rising Platform Stage

Technologies and Libraries: Microcontrollers, nRF24L01 Radio Frequency communication module, CO2 Laser Cutter (for chassis & joystick box fabrication), C++, Python, GitHub, OnShape CAD

Project Overview:

This project involved leading a team of 4 interns in creating a Pokemon-themed "sumo-wrestling" style mobile robot game for the NIU! event. The project comprised two key elements:

• Mobile Battle Bots: Programmable robots designed for sumo-wrestling style competitions.

• Rising Platform Stage: A stage featuring a center platform that elevates for added excitement.

Project Leadership and Management:

• Team Structure: I divided the team strategically, with two interns focused on robot design and programming, while the other two tackled the stage design and construction.

• Knowledge Transfer: Leveraging my experience, I provided training on product life cycle, engineering principles, and design for manufacturability (DFM) practices.

Mobile Battle Bots:

• Iterative Design: The robot chassis underwent multiple design revisions to meet key requirements:

  • Durability: Withstand repeated collisions without compromising structure or loosening parts.

  • Component Protection: Safeguard essential electronics.

  • Battery Efficiency: Enable easy battery swaps.

  • Signal Strength: Maintain clear reception for the nRF24L01 sensor.

• Manufacturing and Prototyping: Oversaw the fabrication process, utilizing an in-house CO2 laser cutter to create unique joystick boxes.

• Flexibility and Redundancy: Implemented dip switches and programming to allow any joystick to control any robot (useful for malfunctions).

• Professional Finish: Soldered all electronics onto prototyping boards for a polished look and secure connections.

Rising Platform Stage:

• Innovative Design: Incorporated an electric car jack to raise the stage's central platform, adding a dynamic element to the competition.

• Hardware Integration: Modified the car jack's remote control by integrating a relay and Arduino. This enabled digital control of the platform's movement (up/down) using a timer.

Project Outcome and Learnings:

• Engaging Event Experience: The project was a success, fostering excitement and showcasing the team's creativity.

• Leadership Skills Demonstrated: Effective team management, knowledge sharing, and project oversight.

• Technical Expertise Displayed: Proficiency in design, prototyping, electronics integration, and programming (Arduino).

• Problem-Solving Skills: Developing solutions for collision resistance, efficient battery swaps, and flexible robot control.
