Our Mission FLL is not just about building robots and competing in tournaments Develop team member skills technical team building research & presentation Technical problem solving can be fun The youngsters do the work Introduce possibility of a technical career 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics LEGO Parts Identification Technic Liftarm 2x4 L shape Technic Liftarm 1x5, 1x7 Technic Liftarm 3x5 L shape Technic Liftarm 1x9 Bent Technic Pin Joiner Dual Axles & Pins Have kids inventory your NXT kit & get to know the parts Important to have all team members become familiar with robot parts. Build small sub assemblies, e.g. gear trains & grabbers 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics Note how NXT parts are all pinned together using Technic parts There are no plates with bumps Motors are strong enough for direct drive – turn a wheel on your robot to feel the gears Motors have built in rotation sensors – programmed in degrees or rotations Take a minute to examine the NXT parts and motors 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics – Parts Pinned Together Note use of pins and axles that hold the pieces together Note direct drive, motor to wheels 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Brick 3 Output ports on top USB port on top 4 Input ports on bottom Enter button (orange) Back button (black) Left & Right cursor buttons (grey) Screen shows program icons Push the Enter button, what happens? Take a minute to examine the NXT brick 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Brick Back 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Brick Firmware & programs stored in flash (like photos on a digital camera) Default inputs: touch = 1, light = 3, Distance = 4 Allowed: 2 touch, 2 light, 1 Distance Default outputs: Left motor = C, right motor = B Allowed: 3 motors (rotation sensors built in) Allowed: (3 - number of motors) rotation sensors 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Brick 12/8/2018 ORTOP NXT Delta - 2006 The complete set of motors and sensors FLL competition uses only touch and light sensors 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Brick The NXT Screen Shows My Files after power on Orange “Enter” button “Back” button below Enter Left & Right “Cursor” buttons Take a minute now, press the enter key, then navigate through the files Turn the NXT off by pressing Back several times until NXT asks “turn off” Confirm with Enter More of the NXT brick controls in the lab Take a minute to turn your NXT on, off 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Motor Forward is Clockwise on an NXT motor Note holes for Axles and Cams A Move block in the program controls both motors The robot moves straight - motors will adjust speed as the robot moves Recommend programming tests for straight and curved movements, single and multiple Move blocks Motors can be part of the framework for the robot Motors adjust speed to run straight, they have position and rate feedback 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Sensors Light Sensor Reads reflection from a built-in IR emitter - (the sensor responds to visible light and into the IR spectrum) (default mode) Or, reads light intensity from surroundings with emitter turned off A “follow the light” program would use the emitter off feature A Calibration procedure is available for more precise light sensing We will go through the calibration procedure in the lab. Note the light sensor is IR sensitive, e.g. it responds to heat. 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Sensors Default calibrate Program readings View White 1023 588 95% 57% Green 22% 34% Black 271 0% 26% We will go through the calibration procedure in the lab. Note the light sensor is IR sensitive, e.g. it responds to heat. 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics - Sensors Touch sensor Responds to being pressed, or released, or bumped (pressed then released) Note axle slot for extending sensor capability 12/8/2018 ORTOP NXT Delta - 2006
NXT Basics – Programming Open Mindstorms NXT, Close the Robo Center Find “Start New Program” – type “move1” and “Go>>”. Click the Move block (gears) – note white box Move mouse so white box is in Start square Click to drop the Move block in Start square Click hour glass Wait block, slide mouse to right and click Touch sensor – move to position to right of Move block. Use Esc key to undo a command Use Delete key to delete a block 12/8/2018 ORTOP NXT Delta - 2006
