| # Antweight Battlebot Batu Yesilyurt (batuy2) Praman (pramanr2) Anthony (arshen2) # Problem Eight teams will compete with their own battlebots in a tournament. The antweight battlebots have the following constraints: Less than 2 lbs, 3D printed plastics, custom PCB that connects via bluetooth to microcontroller, motor or pneumatic fighting tool, and easy manual/automatic shutdown. # Solution Our plan is to be able to control and prevent the opposing robot from moving to win by decision. Controlling the opposing robot is an effective yet simple way to earn points. We plan on having arms that extend out and grab the opposing battlebot, preventing it from moving.The biggest challenge that we predict we will face is the 2 lb weight constraint. This might prevent the use of any additional features such as weapons to damage the opposing battlebot when we have it under control. # Solution Components ## Materials The primary purpose of our robot will be to control the enemy, this means that our robot needs to be resistant to their attacks. Most battlebots will use kinetic weapons, so we plan on using PETG because of its impact resistance. ## Control System The controls will be managed and powered by an STM32 microcontroller, which will direct the 3 DC motors (2 drivetrain and 1 weapon) while also utilizing its embedded wireless communication. The bluetooth module will interface with an external controller (likely PC) and will enable low latency wireless control. The microcontroller will also leverage GPIO and PWM to enable precise speed control and directional control for the motors. Furthermore, we will implement an H-bridge for additional control and stabilization. ## Power System We plan on using a 12v LiPO battery because it would provide us with lots of power for our weapons system while also being light. ## Movement System We plan on using brushless motors to operate 2 wheels on either side of the battlebot. Our winning condition will involve pushing and controlling the other team's robot so higher torque will be more preferred over high speed motors to be able to move around the other team's battlebot. To save weight we will use a high torque motor with a fixed gear ratio. We will sacrifice speed for torque. We will also try to distribute the weight of the robot components over the wheels to maximize downforce for grip. ## Weapon System For our weapon, we plan to utilize 2 arms that would wrap around the other robot to control and prevent it from moving. These arms will utilize a big portion of the weight budget in order to make sure they are strong enough to restrain the other robot and also take hits when not deployed. # Criterion For Success For a successful project, the robot should complete 3 goals. First is the remote control of the robot through bluetooth or wifi from the PC. Second the robot should automatically disable in the event the remote connection is disabled. Third the robot should drive and operate the weapon to a functional degree |
