Parts for a new mini sumo robot

Last September 2012 I started gathering parts for a new to build mini sumo robot. With my previous mini sumo called Quan, I became Benelux mini sumo champion several times. I build that robot in 2005. Last time I participated in the competition in 2009, I became second. Since that moment, the robot has not left the closet for a new match. Now I have plans for a new robot inspired by a mini sumo called Number Two. A mini sumo robot is an autonomous robot not weighing more than 500 grams and limited in size 10 by 10 cm during start.

Parts for my new to build mini sumo

The parts in the picture:

• 2x line detection sensor;
• Brass tubing 0.5 x 8 x 245 mm to strengthen the pencils at the pivot point;
• 8x pencil;
• Rhino 360mAh 2S 7.4v 20C Lipoly Pack;
• 2x ultrasonic distance sensor to detect the opponent;
• Black plastic for the robot frame;
• STM32F4 Discovery microcontroller board;
• TB6612FNG motor control unit;
• 2x Cobra Mini-Sumo Wheels;
• 2x Copal HG16-030-AA-00 motors.

Although I am aware that technology is ever moving forward in a seemingly increasing speed it is still amazing if you compare the microcontrollers available then and now for my new robot.
