=II. Instructions for Challenges=

1. Point Turn
Instructions: 25 cm forward, point turn to the left (180 degrees), back up 10 cm A. In this challenge we must make a robot go 25 cm forward then make it do a 180 degree turn and then make it back up 10 cm.

B. Code: The code is below Step 1: Move forward 1.5 rotations Step 2: Move Wheel C 180 degrees Step 3: Back up 0.5 rotations

D. The programming was hard to figure out and it took some time to get it right. It was a task that was frustrating and time taking.

2. Square
Instructions: Your robot must follow the square drawn on the floor at the front of the room. A. In this challenge the objective was to make a robot follow the outside of a square.

B. Our code is below Step 1: Move forward 1.38 rotations Step 2: Make a complete left point turn Step 3: Repeat step 1 two more times Step 4: Repeat step 2 two more times Step 5: Move forward 1.38 rotations and come to a complete stop.

D.The programming was rather easy to do, the measure of the square's sides were calculated. The amount of rotations needed to preform the one side was also calculated. Then the robot was programed to do a left point turn, and it would turn left four times.

A. For each challenge you must write a short description of the challenge using complete sentences. Please write in 3rd person, scientific writing. B. This is where you should include your programming code by including screen screen shots. You should place all multimedia on [|photobucket.com] and then incorporate it into the site using the embed code. C. For each challenge you must provide some form of multimedia exhibit. This would be images, a short video, an interview, etc. You should place all multimedia on [|photobucket.com] and then incorporate it into the site using the embed code. D. For each challenge you should provide a written explanation of the difficulties encountered with the challenge.

Title of Challenge: Obstacle Course A. Description (Short Paragraph): The challenge was to make an obstacle course and program a robot to be able to go through this obstacle course. Below in multimedia there is a picture of our obstacle course. This challenge can ether be very complex or very easy. Our obstacle course was semi easy.

B. Programming Code (Picture and Written Explanation): (Above is a picture of our code for the obstacle course) These commands show that to start the challenge the robot will listen for a sound to trigger it to start moving through the course. After a few turns later it will sense for a black line to trigger it to stop.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): A few difficulties with the obstacle course was making the robot make exact turns (in the right direction) and making it stop at small black lines. When the light sensor was going on it was hard to make it not stop on the small black lines so that we could make it stop on the big piece of paper. That was later solved by turning the sensitivity lower.

Task 1 (10 points): At your work area on the table come up with a strategy to calculate the velocity of your robot at 30% power over 70 cm. Repeat the measurement 3 times and get an average. Think about the equation for velocity. Carry out your plan and determine the velocity.

a. Brief description and image (snip and you can upload to the wiki- give your image an uncommon file name) of the programming you used to solve this challenge.



b. Description of what made this task difficult for your group.

Nothing really made this task difficult. A hard thing was to make the robot go exactly 70cm

Task 2 (20 points):: At your work area, come up with a strategy to get your robot to accelerate over a 1 meter distance. Have it come to a stop at 1 meter.

a. Brief description and image (snip and you can upload to the wiki- give your image an uncommon file name) of the programming you used to solve this challenge.



b. Description of what made this task difficult for your group.

this task was difficult because the robot had to accelerate over the meter distance. It was hard to make the program work for us and not against us.

Task 3 (30 points):: Determine the velocity of the rotation of the wheels on your robot. Program your robot at 45% power to rotate 10 times. Calculate the velocity of the rotation of the wheels at this power in cm/sec. (Hint: You need to know the circumference of a wheel and remember it goes around ten times!)

b. Description of what made this task difficult for your group.

Calculating the velocity by measuring how long the robot went with 10 rotations and 45% power.

Task 4 (40 points):: On a graph, plot the velocity that your robot travels 1 meter at 20% power, 40% power, and 70% power. Include an image of your plot in your documentation by snipping it. Make sure it has units and axis labels. Using your graph, determine how fast you think your robot wold be traveling if you programmed it to go at 60% power. Calculate velocity in cm/sec. a. Brief description and image (snip and you can upload to the wiki- give your image an uncommon file name) of the graph. b. Description of what made this task difficult for your group.

Task 5 (50 points):: Create an obstacle course on your lab table with building bocks. It should contain one right point turn and 1 left point turn. The robot should stop at the end where you have built a small tower of blocks. Your robot should not knock the blocks over.
