OMG finishing my blog 3

 My robot was constructed using the lego mindstorms NXT kit set and i also used the mindstorms NXT software to program my robot to do the things that i wanted it to do. i tried all sorts of different ideas to make my robot the ideal competitor. I decided on using two wheels on each side because i thought this would have maximized grip and cornering abilities. My robot had no trouble turning around it was the going straight because sometimes the cords could sometimes get tangled around the wheels so i wrapped them around the ultrasonic sensor and also made sure that they wouldn't obscure my robots vision. 

another problem that showed it self was the ultrasonic sensor that couldn't target the opponent as easily as they could target me. i tested the range and i made improvements by alteri

ng the programming a little bit. i decreased the range and increased the charge speed i then tested it with some targets on the ring and this worked because it was easier for the robot to see them so i stuck with the programming for that.

The wheels were a little bit of trouble because they would catch onto each other and wouldn't work properly so i distanced each wheel further away from each other but then my robot had problems turning so i pushed them closer together but there was only a very small gap between each wheel which worked great but didn't help me when i was being pushed out of the ring.
