| ANT-WEIGHT BATTLEBOT Team Members: - Giovanni Escamilla (gme5) - Andrew Bajek (abajek2) - Elise Chiang (elisenc3) # Problem Antweight combat robots, limited to a maximum mass of 2 lb, must function reliably despite aggressive mechanical stress, and demanding control requirements. These systems regularly experience violent impacts, sudden motor stalls, and intermittent wireless links, making fast and dependable coordination between power distribution, control electronics, and mechanical hardware. # Solution Our idea for our 2-lb bot is a two-wheel drive with a vertical drum spinner as our weapon. We will develop our own custom PCB with controls centered around our STM32WB series microcontroller. This controller will not only control our weapon and drive system, but monitor our stress to limit damage done to the battlebot. Overall, our total system will be divided into four sections: power, control, drive, weapon. Our wireless connection to our PC will be bluetooth and work in tandem with our microcontroller to guarantee our success. # Solution Components ## Subsystem 1 - Power Our Power system will give life to our bot with some additional safety features so we are able to compete in the competition. This will include the physical switch to turn off the bot and a voltage regulator so that our controller can use it. Components: - XT60 Connectors (to unplug) - 3S LIPO Battery (11.1v battery) - We could make our own power regulator; if not, we will use LM2596 ## Subsystem 2 - Drive Our Drive system will allow the battle bot to navigate the arena quickly and precisely in order to deliver attacks and avoid attacks from opposing bots. Components: - Two DC motors, one per side (508 RPM Mini Econ Gear Motor) - Dual H-bridge motor driver (DRV8411) ## Subsystem 3 - Weapon The Weapon system serves as the main accessory for engaging the opponent for damage. Components: - DC motor to power the weapon (drum vertical spinner) - Motor control driven by PWM - 3D structures to aid main weapon (ramps, lifters, etc) ## Subsystem 4 - Control Our central brain will center around our STM32WB microcontroller, which will monitor and control our weapon and drive. In addition, monitoring our weapon's motor to limit damage to ourselves. Components: - STM32WB series microcontroller - Bluetooth - PC-based control interface - Real-time reliability - Weapon Motor Stress Sensor # Physical Design - Body The body of the battlebot will house and protect the electronics, motors, while maintaining structural integrity during combat. We will use Autodesk Fusion 360 to model the body and use PLA+ as the 3D printing filament. # Criterion For Success - Weight Compliance: Total Weight: 2lb - Wireless Control: Robot is controlled from a PC via Bluetooth with Failsafe Operation. - Safety: The bot will automatically shut down in the case of a power fault, loss of control signal, or electrical malfunction. - Mobility: Robot runs continuously for 3 minutes without resets. - Weapon Reliability: The fighting tool operates reliably under repeated activation while maintaining electrical and mechanical performance. - Sensor Addition: Some internal or external sensor that makes the robot react in some way - Responsiveness: Inputs in control have a delay of less than 50ms. |
