Path finder

This robot is very cool because it goes forward until it senses an object. It then stops, turns the front wheels one way and then the other to see which path is longer. It then chooses the longer path. I really like this robot!!!!!!

Here's what the program looks like. I haven't commented the code yet. Sorry about that.

Mindstorms with friends

My friends come to my house every week after school on Wednesday to build robots. This week we made these robots. My friends and I built robots that wander around the room avoiding objects in their paths. (My friends' names are Laeo and Ava.)

Tag bot

I really like this robot because it is the first robot I programed to play a game. This robot goes forward until it senses an object. Then it goes backwards. If it does not sense an object for three seconds, it turns and goes in a new direction. As this is going on, you try to tag the robot's light sensor with a beam of light from a flashlight. When you tag the robot, the robot makes a beeping noise. If you tag the robot for a half a second, it will stop then say "game over".

Here's what the code looks like:

Edge finder

When you put the edge finder in the middle of the table, it moves forward until it finds the table edge (using the ultrasonic sensor). Then it moves in reverse to the center of the table, then it turns randomly, and repeats that two more times. The ultrasonic sensor works by sending out a very hi pitched sound that you can't hear. Then the sensor times how long the sound takes to get to an object in front of it and back.

Here's what the program looks like:

Bulldozer bot

This is one of the coolest robots I have made in my whole entire life! I like it because it will find all of the cups no matter where you put them!
