| # ANT-WEIGHT BATTLEBOT Team Members: - Xiangyi Kong (xkong13) - Yuxin Zhang (yuxinz11) - Wenhao Zhang (wenhaoz5) # Problem Antweight (≤2 lb) combat robots must operate under strict weight, power, and control constraints while enduring repeated impacts, motor stalls, and wireless failures. It’s extremely important for the stable and fast interconnection among power delivery, wireless control, and integration between mechanical and electronic subsystems. # Solution We propose a 2-lb antweight battlebot with a four-wheel-drive chassis and an active front roller-and-fork weapon. All electronics are integrated on a custom PCB centered on an ESP32 microcontroller. The system is divided into four subsystems—Power, Drive, Weapon, and Control—allowing modular development and testing. Wireless PC-based control is implemented via WiFi or Bluetooth, with firmware failsafes ensuring automatic shutdown on RF link loss. # Solution Components ## Subsystem 1 - power Supplies stable power to motors and electronics while preventing brownouts, overcurrent damage, and unsafe operation. Components: - 3S LIPO Battery (11.1v battery) - LM2596S-3.3( regulator to output 3.3v) ## Subsystem 2 - Drive Provides reliable locomotion, turning, and pushing power during combat. Components: - Four DC gear motors - L298N (motor driver) - Four wheels mounted to a 3D-printed chassis ## Subsystem3 - Weapon Implements the robot’s primary mechanism for engaging and controlling opponents. Components: - Front roller driven by a DC motor - PWM-based motor control circuitry - Other 3D-printed weapon structure (forks, and wedge guides) ## Subsystem4 - Control Handles wireless communication, motion control, weapon control, and safety logic. Components: - ESP32 microcontroller on custom PCB - Integrated Bluetooth radio - Current sensor for safety monitoring - PC-based control interface # Criterion For Success - Weight Compliance: Total robot mass is less than 2.0 lb. - Wireless Control: Robot is reliably controlled from a PC via Bluetooth with Failsafe Operation. - Mobility: Robot operates continuously for 3 minutes without power resets. - Weapon Reliability: Weapon can be repeatedly actuated without electrical or mechanical failure. |
