My Mini Sumobot (720rpm Prototype Mrk.12)
Here's a sneak peak of my latest sumobot, it's still a prototype. It runs with four 625-720rpm Micro Metal Gearboxes, and are driven by a single L298N motor driver chip. For its brains, it uses an arduino clone, the gizmini328. Its powered by a 3cell LiPo battery.

For its eyes, it uses one Sharp Proximity Sensor for detecting enemies from a far, and uses two short range DIY IR sensors for navigating on enemy target. The bot is also equipped with two floor sensors in order to stay on the ring.

The scoop is still under development, that's why the wedge is not installed yet. By the month of September, the bot is ready for battle, for the national competition. PLEASE WATCH THE COOL VIDEO BELOW :D

The chasis is made out of FIBER GLASS (PCB). I design the PCB layout using fritzing layout design software. To conserve space I mounted the motors directly to my PCB, so that the PCB would act as my chasis. The shell is temporarily made form cardboard.

What's A Sumobot?
It's somehow related to real life sumo wrestling. Two sumobots are placed in a ring, the goal is two push each other out of the ring, any part of the robot that touches outside the wring will be considered defeated. The one who pushed the other opponent out of the ring will be the winner of the round, there will be three rounds in each battle. It's a championship that will test your skills in programming and in building your hardware. There are three divisions in our country the 400g, 500g and the 1kg. It's Fully Autonomous

Specs:
- Uses 5 sensors, 1 Sharp IR Proximity, 2 DIY IR Navigation Sensors, and 2 Floor sensors.
All mounted on a custom PCB
- Uses an 8-bit ATmega328 MCU (Gizduino-Processor)
- L298N Motor Sriver Chip (2A per motor)
- Pololu 50:1 HP MicroMetal Gearbox (620-720rpm)
- Custom PCB DIY Fabrication (double decker)
- Weights 210 grams all-in-all, designed to fight with 500g bots
- Uses C++ Codes in programming Micro Controller
