Lets Learn a few things before doing our project: This will help us strategize and work toward accuracy. Let's learn about coordinates and plotting: Click here to access a site from www.bgfl.org
Lets try this activity by www.sums.co.uk which will help us understand why coordinates and plotting is important: http://www.sums.co.uk/playground/ss3/playground.htm Lets learn about capacity: http://illuminations.nctm.org/ActivityDetail.aspx?ID=6 Explore with the isometric tool: http://illuminations.nctm.org/ActivityDetail.aspx?ID=125 Get a refresher on measurement: http://www.bgfl.org/bgfl/custom/resources_ftp/client_ftp/ks2/maths/measures/index.htm
What is a clock and how do we tell time?: http://www.wmnet.org.uk/wmnet/custom/files_uploaded/uploaded_resources/503/clock.swf Lets learn about timing: http://www.mathsyear2000.org/magnet/minus3/trains/out2.html

In the Ocean (read everything carefully before pursuing):
Setup - Trials and Challenges file has the "Challenge" setup. Open the power point: Click here (links within the file do not work but is located on this site) 1.
4' x 8' floor space marked off by black electrical tape or 4 inch high
frame painted black. You can lightly grid the board putting a
projected image of grids over the area. Make sure the girds measure
out to be 1" x 1" squares.
2. Normally for a good run, proper lighting is a must. However, a good challenge would be to have natural lighting and see if the students can adjust their robots for the environment.
3.
3 to 5 missions need to be setup on the space provided. Mission will
be set to Navy and USS Missouri tasks. Always have a theme ready.
a.
Rescue - black electrical tape going from one end to another in a curvy
line. Robot follows line to end point to rescue and then returns home. b.
Data retrieval - home base is set and robot needs to go and collect
data modules. Usually 3 need to be picked up for full points. Must
return home. c.
Delivery system - this starts from another home base set on the board
and goes to another side of the board to deliver something. Accuracy
is needed for this. Must return hom. d. Patrol system - this starts from main base and robot would travel around finding check points and when all is done, it returns home. e.
Activate main machine - this starts from base and robot needs to find
the main central machine and activate it. Must return hom. f. War - serve and protect. This requires 2 players. Both sides will war against the other. Rules are made up by instructor. This can go up to 4 players. Robots must find each other. g.
Exploration - explore the seas. This starts at base and robot should
navigate around taking data (almost like patrol). It must return to
base with data. 4. All of this will be done on the floor space provided. All of the robots must be autonomous (meaning working on its own without human intervention). 5.
Form teams per a kit, no more than 6 and no less than 2 per team. Each
team will need pencils with erasures and at least 20 8 1/2" x 11"
sheets of paper or larger for the planning. 6. All batteries must be charged. All firmware must be on the NXT. All NXT-G software must be loaded on computers. 7. Wash hands before using equipment. Very good practice. 8. Safety goggles, proper clothing, shoes, and hard hats can be used. Most important to Robotics is Safety Goggles. - Optional. 9. Know all the tasks that will happen and all props must be built and setup on the board/floor space. 10.All communication robots or devices (if any) must be all built, programmed, and functional. Pre-Activity: 1.
History of the USS Missouri - brief and what it's mission was. This
should be a setup for the students and adults to feel a sense of
mission for the next part. 2. Talk about what the USS Missouri represents today. What is the sense of mission, not only about war and peace, but also technology and safety. 3. Bring them to the tasks of what each team will be doing. We are talking about the future! Get them excited about what the future may bring and how we are preparing. 4. Break up for tasks which will be done all in steps.
5. PRE-TEST or PRE-SURVEYS must be taken during the learning process before the activity can begin.
6. Robotics lessons. At any level this is always good to do. Especially for beginners!
7. Students do all tutorials necessary to start activity.
8. Make sure you do qualification rounds using the Trials and Challenges: Trialschallenges.pps (links within the file do not work but is located on this site) Activity (Take pictures of all steps from beginning to end as this is proof of the project's success.): Step 1: Plan and design - pick a mission, plan and design for that mission. Each mission will be done in this fashion with all the steps. a. Do all measurements with holes on beams. Measurements can be done at the mission site. 1) See if any of these machines fit what your mission requires (these are only ideas) - from NXTLOG2.0 (Guard): http://mindstorms.lego.com/nxtlog/projectlist.aspx?tag=guard 2) Check this out as well - from NXTLOG2.0 (Shooter): http://mindstorms.lego.com/nxtlog/projectlist.aspx?tag=shooter 3) Try this too - from NXTLOG2.0 (Rescue): http://mindstorms.lego.com/nxtlog/projectlist.aspx?SearchText=rescue 4) This one is worth it as well - from NXTLOG2.0(Spy): 5) Check this out - from NXTLOG2.0 (Explorer): http://mindstorms.lego.com/nxtlog/projectlist.aspx?SearchText=explore 6) Try this - from NXTLOG2.0(Patrol): 7) See this - from NXTLOG2.0(Launcher): b. All data must be written to help in the planning and designing process. c. Do a blue print on a large sheet of paper. d. You will also need to plan your strategy on how this mission will be tackled effectively and efficiently. Question: Will one design fit all missions?
Step 2: Do a flow chart on paper on how the events will unfold. Plan each movement carefully. Step 3: Build according to design and do the best in using all kinds of parts to get your future ships to look the way you planned it. Hint: Make sure you leave room to plug in the USB cord to the computer for programming. Sub 3: You can use colored construction paper in the end with some tape to make your ship look more outstanding. Step 4: With your robot built, use the "View" function with whatever sensors to take enough data for your mission to go smoothly. a. You may want to measure out the amount of degrees or rotations it takes to go from home base to the mission objective. b. You may want to take light data or know what dark is on the light sensor. c. You may want to take temperature measurements for something that your robot has to sense. d. You may want to take ultrasonic measurements for your mission if it is permitted. Step 5: With all the data you took and your robot built, oh and your flow chart, you will want to attach your robot to the computer and start programming. Hint: Put beeps in between certain blocks and listen for those beeps when your program runs so that you know where problems are when you do your test runs. Step 6: After uploading your program to the NXT brain, you will want to take your team member(s) to the site and test your robot. Make sure you wait your turn. Hint: Keep your robot turned off until you are ready to test on the floor. Never test on the table or around where people are walking. Do it in proper area.
Step 7: Take down all data on problems and solve with educational guesses. Take it back to your table and work on problem. Write all problems and solutions down.
Step
8: Once you've got it working, grab an adult (Robotics Instructor)
and have them watch your mission. If they pass it you will need to
move on to the next mission.
Final activity: 1. Scores are taken and posted by teams.
2. Everyone is encouraged to cheer for each other.
3. POST-TEST or POST-SURVEY is given here.
Post activity: 1. Gather all surveys/tests, team paper work, photos, and print out programs from computer. 2. Put it into a binder for future work to be done for grant foundation.
Take it several notches up!
Required: 1. Mini helicopters that can fly multi-directional to do rescue or delivery off of a robotic platform that moves. Build: 1. Build a platform that travels around the mission area and seeks out specific areas that need help autonomously. 2. The platform will need to stop when the helicopter launches and wait until the helicopter comes back. Think about it: 1. How will the platform (ship) know where to go? 2. How will it know when to stop? 3. How will it know when to go? |
