Retro Robot with Electronics

thingiverse

We're going to build a Retro-style walking robot with flashing lights and laser type sounds. Along the way, we'll learn about tolerances, simple mechanics, and basic electronics. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: No Supports: No Resolution: Standard Infill: 10% How I Designed This The 3D printed parts were designed in Tinkercad. Overview and Background This is a remake of a 1960's style Horikawa Walking Robot with flashing lights and laser sound. Our objectives are to learn basic electronics, design concepts, and simple machines. Standards: National Science Education Standards Grades 5-8 (ages 10 - 14) CONTENT STANDARD B: Physical Science: Students will develop an understanding of Motions and forces, Transfer of energy. National Science Education Standards Grades 9-12 (ages 14 - 18) CONTENT STANDARD B: Physical Science: Students will develop understanding of Motions and forces, Interactions of energy and matter CONTENT STANDARD E: Science and Technology: Students should develop Abilities of technological design, Understandings about science and technology Standards for Technological Literacy – All Ages Lesson Plan and Activity: Step 1: Attach the head to the torso/body of the robot with a good amount of pressure. The "neck" below the head has a lip that secures the head to body. Step 2: Insert the front and back leg pieces into the feet. Step 3: Add the rollers to the bottoms of the feet; there are four rollers in total, two per foot that help the robot glide during movement. Step 4: Attach the leg pins to the gear box and secure the left and right legs to body. Make sure to put the longer leg piece in front and align the pin from the gearbox with the long slot on the front leg piece. Step 5: Secure the micro motor to the upper part of the gear box and run the wiring through the hole in the back. Step 6: Insert the gear box and leg assembly into the body using the groves provided. Step 7: Wire the electronics for the ray gun sound effects and flashing lights. Duration of Lesson 3 - 60 minute periods Preparation To prepare, you'll need: Small Breadboard or Breakout Board Assorted Wire Jumpers 3v mini hobby motor 555 or 556 Timer Chip 3 - Resistors 2 - .10 uf capacitors 2 - LEDs Rubric and Assessment These reflective questions will help assess student understanding: I. What was one thing you liked about your design? What is its main weakness? ii. What is one thing you would change about your design based on your experience? iii. How would you modify the instructions to create a better experience for participants?
