Lego Robot Kits (Cont’d) • Motors are what make your robot move. • Motors can run forward or backward and at different power levels. • Motors are connected to the microprocessor with motor cables. 2/23/2019

Lego Robot Kits (Cont’d) • Sensors give your robot information about itself and its environment. • The touch sensor detects if the robot has run into something. • The light sensor measures the amount of light in the room. • The rotational sensor measures how many times the robot’s wheels have turned. 2/23/2019

LEGO™ Parts - Beams Beams are structural components. • They are named by the number of LEGO™ “bumps” on the top. • Beams have holes. Axles or pegs can be placed in the holes. 2/23/2019

LEGO™ Parts – Plates and Bricks Plates are flat. • Plates can have holes. • Plates and bricks are named by the number of LEGO™ “bumps” on each side. • Bricks are rectangular pieces. • Bricks are used for structural support. 2/23/2019

LEGO™ Parts – Axles Axles are used to attach wheels and gears. • Axles are named by how long they are in LEGO™ “bumps.” For example, a #8 axle is the same length as a 1 x 8 beam. 2/23/2019

LEGO™ Parts – Wheels • Wheels come in a variety of sizes. • Large wheels make your robot go fast. Small wheels make your robot go slow. • There are two types of tires. Tractor tires have a checker-board tread. Regular tires have a wider, race car tread. • Treads can be used for tank robots. 2/23/2019

LEGO™ Parts – Gears • Gears are wheels with teeth that mesh together. • Gears are used to change the speed and strength of your robot. • They are named by the number of teeth they have. 2/23/2019

LEGO™ Parts – Bushings and Pegs • Pegs are used to connect beams together. • Bushings are used to hold wheels or gears on their axles. 2/23/2019

Test Your Robot Following a line Picking up an object Pushing the brick 2/23/2019

Test Your Robot (Cont’d) Pushing the brick Steps: The robot moves forward until it detects the dark line. (See instructions in Robot Educator >> Home >> Common Palette >> 16. Detect Dark Line >> Programming Guide). The robot follows the dark line until it comes in a straight line with the brick. (See instructions in Robot Educator >> Home >> Common Palette >> 17. Follow A Line >> Programming Guide). Either fix a distance or fix a time for following the line so that the robot stops as soon as it comes in a straight line with the brick. The robot takes a 90 degree turn towards the brick. (See instructions in Robot Educator >> Home >> Common Palette >> 08. Drive In Squares >> Programming Guide). The robot moves forward until it encounters the brick. When it comes to the brick, it pushes the brick to the end of the table. (Calculate the distance the robot will travel to reach the end of the table and stop.) Fence Brick Step 1 Step 2 Step 3 Step 4 2/23/2019
