Through out the week of 9/9 and 9/16 i had to build a robot. When we were introduced to this project to build the robot we had to work in group of two, i worked in a group of three. Me and my group struggled on building the robot because our box had missing pieces. However we managed to finish the robot in time. We build the robot following 6 main steps:

1)Preparation.

First we attached double black peg connector  vertically on the top holes of the machine and a single black peg connector in the middle hole of the machine.

2)Attaching the motors

We attached the motors one on each side of the machine, by attaching it to the peg connectors on both side of the machine.

3)Support Motors

We took an 11-holed rounded beam and attach two short black connector pegs to the outside holes then we attached the pegs to the back of each motor.

4)Wheels

We build the wheel using axle wheel and a hub, attach them together to make the wheel.

5,6) Wheel base and Final Attachment

In order to make the wheel base we used 4 L beams, 3 of different sizes( small) and one large. On the large part of the beam we connect two connector pegs.In the hole between the two connector pegs on each beam we attached an extended black connector peg. Then we attached two small beams to the  pins below the other beams. Then we connect them together in order to finish the robot.

On the second day working on the project we worked on how to make the robot move. This part was very hard fro me because i was having trouble finding the right powers in order of the robot to pass around two rulers that would make 2 ft. first we had to connect the robot with the a computer through ans USB cord. this time the robot could move because also had a battery.i made the robot move though using the Lab view program. Lab view helps to control the robot power.   After many tries i didn’t find the right power in order to make to make the the robot go around two feet. Our task was also to get to get sound into to robot.

During the last class, we used the robots again. The first thing we did was measured the diameter the wheel, and find the circumference of the wheel in meters.  (circumference= p*diameter). The circumference is very helpful because indicates the the distance traveled. For example if the wheel turn was 3 cm and the car moved forward 3 turns then the distance traveled was 3 cm. we also had to calculate the percentage error. Using the program lab view we could control the robot input  data such the time power for both wheels and the computer would give us the number of wheels turned the velocity and the distance. In order to find the percentage error we would subtract the computer distance from our distance, dividing that by our distance plus the computer distance all over two, then multiply that by 100. (My distance was from measuring it with a paper ruler combined together. Overall my percentage error was not that big of a number. I believe that the percentage error might have been caused by my wrong measure of distance since it was a paper ruler.
