Terrified Robot Pet

... That you can scare by stepping on it! Poor guy :'(

IMPORTANT NOTICE: THIS IS NOT THE FULL INSTRUCTIBLE, JUST THE ASSEMBLY OF ALL THE PARTS. EVERYTHING IS STILL HEAVILY IN DEVELOPMENT, A COMPLETELY REFINED&TESTED VERSION IS COMING SOON.

Components

• A 3d printer
• Tiny nuts&bolts (use the ones that fit in, locknuts like Nylock are preferred)
• Superglue
• 8 50 mm bolts

Electronic components

• A USB b cable
• An HC-SR04 proximity sensor
• 2 NPN transistors
• 2 Diodes
• 2 270 Ω resistors and 1 10kΩ resistors
• A tiny button (6mm in height or more, at most 16 mm in width and length)
• A 9v battery
• A 9v battery clip
• A breadboard
• An Arduino Uno
• A 6v dc motor
• Wires
• Springs

Below is the full view of the model. Use it to complete the upcoming steps.

Print out the following with a high resolution.

Attach the 9v battery by gluing the heads of all of the bolts into the dedicated holes and securing them with a nut

Attach the Arduino. The nuts should be inside the robot, contacting the motherboard, not the other way around.

1. Insert and glue all the poles as shown on the model (DONT GLUE THE GEARS)
2. Attach separate side parts and lids by using bolts

Place springs and 50mm bolts in the circled spots, and attach the top part. Nuts should contact the top part, not the bottom.

Place the breadboard on top of the motherboard and do the wiring.

Place the button and attach the proximity sensor as shown
