This is a picture of our robot that is made out of legos
from my computer science class.The robot is powerd by a
battery pack that is rechargable. The objective of building
the robot was to see if our group could get the robot to
stop moving once the touch sensor is touched. The touch
sensor is supposed to help the robot know it's suroundings.
If it were to run into a wall then it would stop and backup
away from the object or wall it has run into.
This is a picture of the coding that our group used to
program our robot and tell it where to go. It is what makes
the robot move around and get to where it is being told to
go to in the room.
This is a picture of the gears that the robot used to
move around. They were attached to the brick of the robot
which is what controls them and tells the wheels how long to
rotate and how far to travel.
The brick is where all of the wires are connected. They
connect from the sensors to the brick and depending on which
wire is connected to what it communicates to the robot
whenever it hits the wall of detects an object in front of
it.
In the video above is a demonstration of the robot
that my group made out of legos and a motor that helped it
move the car around the room (the brick above this). Our group
also worked on programming the robot's sensors to follow colored
tape that we place on the floor. The sensor detected red, green,
and blue (RGB sensor). Whenever the sensor detected one of the
three colors it began to move forward and proceed along the tape
path. If the robot's sensor lost the tape then it is programmed
to turn 180 degrees and look for the tape the robot lost driving.
The only problem we had with the robot trying to find the tape was
that it did not drive straight and kept losing the line of tape and
kept making circles around it. If I could change anything that our group
did with the challenge it would be to make sure that each motor for the
wheels was distributing the same amount of tire rotation to each side
to see if the car would drive any straighter.
