Day	Class work/ Concepts		Activities	Extensions/Alternatives
1-2	Course Introduction-What is Lego Robotics? Solidworks- From Dream to Design IRobot Video Classroom Rules- How you are dismissed Expectations Real-world Connections- Big Dog, ATM,etc.		Introduction; partners; learning/sorting the various types of Lego parts "Messing About" with a limited palette of parts- In 15 minutes, build something of Lego pieces that expresses something about you- interests, origin,etc.	Video: The Growth Mindset Video: SuperBowl Ad- Amy Purdy- How Great I Am Introduction to Video Journaling- begin collecting images and video clips, saving to folder

3-5	Create frames, surfaces, and pivots using Technic studless building. What are the differences between the different pins? How can you extend an axle? How can you attach an axle to a beam? How can you attach a beam at a right angle?		(1) Build a box with a hinged lid that will contain two balls or similar objects. Challenge Level: Include a Latch Playing with parts, students begin learning to build a stable structure that performs a task. Emphasis on studless Technics building techniques. Document progress in video	Journaling with Ipads and I-Movie Alternatives: (1) http://www.legoengineering.com/a-week-in-the-life-1-play-well/ "...Students are given the grey and black pins and told to write down five differences based just on observation. Then they are given beams to put the pins into and asked to use manipulation to come up with some more differences. This leads to a discussion of friction and the possible uses of these pins and ends with a call to use this method of observation and manipulation throughout the class...." (2) Build a fishing pole at least 24" long of lego pieces with a string at the end that can hook wooden 'fish' Challenge Level: Include a gear and crank reel to reeel up the line.

12-13	Silly Walks: You are to create a robot that “walks.” It doesn’t have to literally walk (e.g. two legs, step-by-step), it can’t just “roll on wheels like a car.” Since the project is called “Silly Walks,” also looking for some silly movement! Monty Python: Ministry of Silly Walks Detailed Description Examples(Tufts): https://www.youtube.com/playlist?list=PL8FDFC770343D3280 https://youtu.be/YmGOgkFKvr8		Write first NxT-G program- sequence beam, move blocks, display block, sounds, sensors- EV3: Program Motors B&C to run for 5 seconds Assignment Group Project: The Wave https://youtu.be/Zk278V75wY4 Ian Chow-Miller: Doing the Wave- Group Behaviours http://www.legoengineering.com/a-week-in-the-life-2-starting-to-wave/	Challenge level: http://youtu.be/fvghHG3mAwc See also Theo Jansen Strandbeest ( http://youtu.be/rebf6-pQhF0 ).

20	Feedback Loops Presentation: EV3 Line Follower		Feedback loops enable continual adjustment of performance based on results Line Follower Weapon Moves if opponent sensed Use color sensor to choose navigation path	Color Line Follower: Using color sensor and multi-case switch statements- program your robot to follow a track marked in 3 colors slow, medium, and fast http://youtu.be/3nD7PKcPpWw Blind-fold walk

	Monitoring Multiple Sensors		Multiple sensors can be monitored using a series of switches in a loop, 1 for each sensor. This is called polling. Walk the Dog	Handout: "Walk the Dog"- Use pushbuttons to guide robot

	Complex Behaviors		Create complex behaviors by stringing together individual behaviors loops conditioned by time or sensors-i.e., follow a line until an edge sensed, then back up, turn, and go down a ramp until a line crossed, then do sumo-bot, etc. Go to Line, wait for trash to be placed in receptacle, then turn around, dump it, and return for more( use 3-motor robot)	Video: Path-clearing Robot
