Building your First Bot

Approx. Time: 
Use a small box and your imagination for a simple, yet amazing first robot. Attach a sensor, tri-color LEDs, and a servo. Hot glue some feathers, popsicle sticks, and pom-poms and voila…your first robot!

Step 1: Gather Materials

1 Duo Controller, 1 USB Cable, 1 Power Supply, 1 Light Sensor, 2 Tri-color LEDs, 1 Servo, 1 box, scissors, ruler, pencil, utility knife, hot glue gun, and craft materials such as feathers, pipe cleaners, felt, popsicle sticks, craft foam, buttons, or beads.

Step 2: Attach Tri-color LEDs

Cut out two holes in the front of the box and insert the LED lights. Use hot glue to secure parts. A small screwdriver is perfect for punching holes through cardboard.

Step 3: Attach a Light Sensor

Cut out a hole in the front of the box and insert the sensor. Use hot glue to secure and remember to leave space for the wires to connect to the controller.

Step 4: Attach a Servo

Cut out a hole in the back of the box and insert the servo. Use hot glue to secure the parts. Make sure you leave enough space to allow for movable components.

Step 5: Connect the Components and Program

Connect all of your components to the Hummingbird Duo controller. Use the connector tool from your kit or a small flat head screwdriver to push down the desired terminal, insert wire, and release. Program the lights, servo, and sensor using a variety of programs including CMU Create Lab Visual Programmer, Scratch 2.0, Snap!, and Ardublock.

Step 6: Decorate Your Robot

Glue on fur or paint scales for an animal or monster. Add a tail with a popsicle stick or pipe cleaner and attach to the servo. Use Styrofoam balls to make eyes and diffuse the LED lights. This example uses construction paper, oak tag,  and popsicle sticks to bring a favorite nursery rhyme to life.
