MEET THE ROBOT

Ladies and Gentlemen, meet Crank. Crank moves at a staggering small amount of distance per second per command, and it can even play music!

About Me

I like computer science for the freedom it offers in creating individualized and personal solutions to problems. This summer, I honed my instrumental skills and sang a lot. Music is actually a really big part of my life.

Today we tested out the IR line sensor located underneath the robot. We managed to construct programs demonstrating that the sensors were receiving input, and all four of us used that input to create a "safety net" for the robots stoping them from driving off the edge. Graham used my computer to test his robot and Carmen used Tim's to test hers.

Progress on September 7, 2012

Today, we wrote programs to retrieve input from the four types of sensors on our Robots: the two sets of IR sensors, the line sensors, and the photosensors. All four of us were successful in running our programs after Carmen and Graham troubleshot their computers.

Sensor Observations

IR sensors on the Fluke outputs in multiples of 640 from 640-6400, with the higher number reflecting a closer distance.

Photosensors output in ranges from the low 1000's to the high 65000's with the lower numbers being brighter.

Here is some data collected from all four members of the group.

Robots Got Talent Assignment

Here's a picture of Crank's art exhibition :).

Here's my code!

Prelab Questions

1)It will sing song of storms just by going through a sequence of seamless robot.beep commands.

2)Crank will draw a heart with a sequence of robot.motor commands.

3)Crank’s surprise ability will be a guard dog like functionality. It will move randomly then seek out anything in the range of the rear IR sensors. Once something enters the sensor, the while loop will break, Crank will emit tones, and the robot will stop.

4)The algorithm will be a routine that the robot goes through with each task separated by a wait command.

We worked with the Braitenburg robots today, including the Alive, Aggressive, and Coward models. My group members (Carmen, Graham, and Tim like before) and I also had to experiment with additional models, so I chose the Paranoid model. The paranoid model is a light seeking robot that moves forward when it detects light and turns when it does not. Through a combination of while and if loops, I managed to get the robot to turn and move fluidly once a light was shined into its forward facing light sensor.

Answers to Pre-Lab: 1) Record photos and have users parse data for use.

2) Robot will move according to user input then stop and take pictures, allowing the user to judge what to do next.

3)We take pictures and edit the pictures to draw boxes around lost scribblers.

4)We're going to use pen and paper
