| # Antweight Battlebot Nandika Vuyyuri (vuyyuri2) \ Gauthami Yenne (gyenne2) \ Jingyu Kang (jingyuk2) # Problem The goal of this project is to create an antweight battlebot that would weigh less than 2 lbs in order to participate in the Antweight Battlebot Competition. The criteria given are that all robots must have clearly visible and controlled mobility; must be controlled via either Bluetooth or WIFI using a microcontroller with an manual operation for disconnection; and rotational blade which would contact the arena 5 inches above the ground level and could come to a complete stop within 60 seconds. # Solution The battlebot will be mounted with a tombstone attacking mechanism in order to disable the opponent’s vehicle. # Solution Components ## Power System: We need a max of 16V considering the motor we are using for moving our robot around so we plan to use Thunder Power 325 mAh 3s battery (THP 325-3SR70J) which is 35g and is the lightest battery we could find that met our requirements. Other battery options weighted about 65g to 105g which would be too heavy to meet the criteria since the weight limit for the entire battlebot should be about 900g. \ Another option is to use flat lithium batteries since the weight of the batteries are significantly lighter than the regular batteries. However, the problem of this would be that the power would not be sufficient enough for the battlebot to move and perform the tasks required as most of the lithium batteries cannot produce significant power at a single instant but rather is a long lasting battery. ## MCU: The ESP32-C3 (ESP32-C3-DevKitM-1), which is known for its low power consumption, will be used for connection between the battlebot and the controller utilizing its built-in Wifi and Bluetooth system. We will use Arduino IDE in order to program the ESP32-C3 to control the robot. We will use this to control the robot’s mobility and attacking mechanism. \n We have access to debugging and flashing tools that are compatible with the ESP32-C3 MCU. ## Attacking mechanism: We plan to use the Emax RS2205 2600KV motor which is 30g. This motor has a fast RPM and is often used for drones actually which we are hoping will be a powerful attacking mechanism. ## Robot mobility To maneuver the battlebot we will use a dual H-bridge configuration using the DRV8833 motor driver paired with high-torque Pololu Micro Metal Gear Motors and integrate the parts with the ESP32-C3-DevKitM-1. ## Materials We plan to use a mixture of lightweight PET-G, ABS, and PLA+ materials. The primary reason for this choice is since they are more durable and flexible as well as heat-resistant which would be ideal for the nature of battlebots. Furthermore, considering majority of the parts would be created through 3D-printing, we assume that ABS or PEEK filament, which is primarily used for 3D-printers, would be ideal. # Criterion For Success Our High-level goal is to maneuver the robot away from the opponent with precision and control. Another goal is to have a horizontal spinning attacking mechanism which is ‘powerful’ enough to knock out robots of other shapes should not just ‘flick’ the other robot but actually make a significant impact to disable the opponent’s robot. |
