RoboSumo

RoboSumo resembles to the traditional Sumo wrestling competition. Here two Robots fight each other and tries to push the opponent out of the arena. The Robot with higher torque, higher stability (lower Center of Gravity) and good strategy will easily win the competition.

This was my 2^nd attempt to make a manually controlled Robot. I decided not to use Radio Frequency remote controll, as I faced some frequency interference problems during RoboHunt competition. So, I controlled this Robot using a Mobile phone.

Technical Specifications:

Operated by Mobile Phone.
Two 150 RPM, 12V, DC geared motors.
Three Li-Ion batteries (4.2*3=12.6V) of 1800 mAh.
Two wheel drive with two beads as supporting wheels.
In space integrated turns and angular turns.

Flaw in Mechanical Design:

Because of wrong height to width ratio, Center of Gravity of Robot is very high and it is not stable, a small jerk is enough to make it topple .
This was corrected in all other designs.

Achievements:

This was my first Robot that was built in very less time. This was built in just 2 days of time.
- Day one, for Mechanical construction.
- Day two, for electronics, DTMF decoding and Microcontroller programming.
