CHAPTER 1

MARVELOUS MOVING ROBOTS

Robots are incredibly fascinating to people of all ages. Both young and old enjoy designing and playing with them, and today, robots are more amazing and useful than ever. Robots are used to carry out tasks in factories that would be too messy or repetitive for humans to perform. They protect humans by seeking out and detonating explosives and by investigating hazardous environments to check for substances that could harm people. Robots perform vital functions in the fields of medicine and space exploration, as well as being used in everyday life. For example, scientists are developing robots that sense motion in your home and take photos of possible intruders. They can even recognize familiar faces! What will the robots of the future be able to do? Maybe you will become an engineer and help shape the future of robotics!

With the projects in this chapter, you can create LEGO robots with mechanical moving parts. While these robots are not programmed by computers, they will let you explore principles of mechanical engineering. Build feet that pedal on their own, use gears to control head movement and even construct a robot that transforms into a car.

RYDER THE ROBOT

This zippy little robot has a clever mechanical element — give him a push and his feet pedal along! Movable leg joints and feet attached to pistons create amazing lifelike motion. While one foot moves up, the other goes down. Try letting your robot pedal his way down a ramp. The steeper the ramp, the faster he'll pedal!

HOW IT WORKS

Ryder the Robot is constructed with a cam (a wheel with an off-center axle) driving a foot. If the feet (the Technic liftarms) were attached to the center of the gears, they wouldn't move up and down at all but instead would stay in the same position relative to the axle. By attaching the feet off-center, the wheel (the gear brick) becomes a cam, causing the feet to move. Circular motion is converted to linear motion. When humans walk, the knee moves in a circle in much the same way, although the cause of the movement is contracting muscles rather than rotating wheels. Isn't it interesting that mechanical bodies have similarities to human bodies?

STEP 1: Gather the bricks shown for building the robot's head.

STEP 2: Attach three 1 x 2 bricks and a 1 x 2 plate to a 2 x 4 plate. The 1 x 2 plate is in the front.

STEP 3: Add a 1 x 2 yellow plate and another 1 x 2 light gray plate.

STEP 4: Attach the 2 x 2 truncated cone to the turntable. Place this on top of the robot's head. Attach the light covers to the 1 x 1 bricks with a stud on the side.

STEP 5: Place the eyes on top of the head and add a 1 x 1 brick behind each one. Add a lever to make the robot's antenna.

STEP 6: Start building the body. Grab two 2 x 4 dark gray bricks.

STEP 7: Add a 2 x 4 dark gray brick and two 1 x 4 light gray Technic bricks.

STEP 8: Add two 2 x 4 green bricks and a 4 x 4 green plate to the robot's body.

STEP 9: Place three more 2 x 4 dark gray bricks on top of the body.

STEP 10: Add two 1 x 4 dark gray bricks and a 2 x 4 dark gray brick. Then use 1 x 1 round bricks to decorate the front of the robot's body.

STEP 11: Place two 1 x 6 dark gray plates on top of the body and add a 2 x 8 light gray plate in the middle.

STEP 12: For the shoulders, place a 1 x 2 dark gray plate with a ball on each side of the body. Then add a 4 x 6 dark gray plate.

STEP 13: Add two 1 x 6 dark gray bricks and two 2 x 3 green bricks with a curved end.

STEP 14: Finish up the body with a 4 x 6 dark gray plate and a 2 x 2 turntable.

STEP 15: Attach the robot's head to the turntable. Now his head can spin!

STEP 16: Build the robot's arms. Each arm has a 1 x 4 green plate attached to a 1 x 2 light gray plate with a socket on the end and a 1 x 2 light gray plate with a socket on the side. Then add a 1 x 2 dark gray plate with a ball on the end and a 1 x 2 light gray plate with a clip on the end.

STEP 17: Attach the arms to the robot's body.

STEP 18: Now build the mechanism that makes the robot pedal. Gather the bricks shown. The black bricks are 1 x 8 Technic bricks.

STEP 19: Stack the bricks as shown.

STEP 20: Build the wheels. Find four 40-tooth Technic gears, four light gray pins and two 1 x 7 dark gray Technic liftarms.

STEP 21: Attach the liftarms to the gears. Make sure that each liftarm is attached to the equivalent hole on both gears.

STEP 22: Grab the bricks from Step 19 and two black axles (4 studs long).

STEP 23: Attach the wheels to the base by sliding the axles through the center X-shaped axle hole on each gear. Make sure that the liftarm on one side is up while the other one is down. It's easy to move the liftarms after the gear is attached to the axle. Just pull out the pins and make adjustments if needed.

STEP 24: Build the legs. Each leg has two 1 x 6 Technic bricks and three light gray pins.

STEP 25: Attach the legs. The legs will connect to the light gray Technic bricks on the robot's body and the dark gray liftarms at the bottom. Once the legs are attached, your robot is complete!

Push your robot and watch him pedal! It's also fun to let him move on his own by putting him on a ramp. Try experimenting with the height of the ramp. How fast can Ryder the Robot pedal without tipping over?

SATELLITE THE ROBOT

Build a cute little robot with a big personality. His funny mouth will make you smile! This robot also has a fun trick to perform. Turn the knob on his back and his head rotates from side to side with the help of two gears inside his body. Build him with a clear front so that you can see the gears in action. If you don't have clear panels, substitute with windows. Or just build the front of his body with regular bricks.

HOW IT WORKS

Gears are super useful mechanical devices! They can be used to change the direction that something rotates or to change the speed of a rotating part. In this project, gears are used to change rotation on a vertical axis to rotation on a horizontal axis. Inside Satellite's body there are two gears whose teeth mesh together at 90-degree angles. When you turn the knob on his back, the vertical gear turns. The teeth of the vertical gear connect with the teeth of the horizontal gear, causing Satellite to turn his head.

STEP 34: Place the 1 x 4 brick with four studs on the side under the front of Satellite's body. Then add tiles with buttons and gauges.

Your robot is complete! Try turning his head with the knob. The moving head really makes him come to life! Pretend that he is communicating with the other robots or planning a mission to explore outer space. His hands can hold tools or other accessories.

TURBO THE TRANSFORMING ROBOT

Use your bricks to create a robot that transforms into a car, then back to a robot again! The spoiler on the back of the car unfolds to reveal the robot's head. Unfold the arms and flip up the headlights to create feet. Then your robot will stand on his own!

HOW IT WORKS

When engineers are designing machines, they must create moving parts that have the correct angle of rotation. Think about a living room recliner. The joints in the chair's mechanism must move (and stop moving) at certain angles for the chair to be comfortable to sit in. You wouldn't want it to be flat like a bed! Turbo's head needs to rotate nearly 180 degrees in order for it to look like both a car and a robot. By using a plate with a handle and a plate with clips as your joint, you can create an almost 180-degree rotation.

Turbo's arms use ball and socket joints. This type of joint can rotate on more than one plane. That means that the joint can rotate up and down and also side to side.

DID YOU KNOW?

Your hip and shoulder joints are ball and socket joints, similar to the joints in Turbo's arms! Can you imagine what it would be like if you could only move your shoulder in one direction? There would be so many things you couldn't do, like reach back to buckle your seatbelt or swing from the monkey bars. Our bodies have a really fantastic design!
