Homemade Robotics Kit (Holiday Gift Idea)
- by KitchenPantryScientist
With a few simple technology and art supplies, you can put together a simple kit that lets kids design and build bristle bots, art bots and light-up creatures.
The Science Behind the Fun: Hooking an unbalanced spinning toy motor to a brush sends vibrations through the bristles. The vibrating bristles move the brush, and anything attached to it, around on a flat surface. Make a disc robot by attaching toothbrushes to a CD and attaching a motor, or make a drawing robot with legs made of pens.
I’ve included ideas for items to put in a kit, along with a tech supply list and photos of the robots from STEAM Lab for Kids. Use your imagination for art supplies! Pair the kit with a book, like STEAM Lab for Kids (Amazon.com), which has instructions for making bristle bots, art bots and light-up creatures, or let tech-savvy kids take the reigns and start building!
LEDs, alligator clip test leads, toy motors and batteries let kids assemble simple circuits. (Supply list below photo)
Basic 3mm and 5mm through-hole LEDs (Art Bot, CD Bot, Light-Up Creature)
Small alligator clip test leads (Art Bot, CD Bot, Light-Up Creature)
AA battery holders (Art Bot, CD Bot )
AA batteries and 9V batteries (Art Bot, CD Bot )
9V battery clip snap-on connectors (battery snaps)
3V coin cell batteries (Light-Up Creature)

(Find these supplies at your favorite bricks and mortar location, like Axman Surplus stores, or get them online at Amazon.com or another tech retailer.)

Paper and plastic cups, brushes, toothbrushes, duct tape, zip-ties, and CDs all make great building supplies, and a glue gun always comes in handy.
Use your imagination for the art supplies.
And if you’ve got a kid who likes to sew, it’s fun to add supplies to make sewable circuits!
Sewable electronics: coin cell battery holders, sewable LEDs, snaps and conductive thread

Here are instructions for building a simple bristle bot.
CD Bots from “STEAM Lab for Kids”

Robots took over the driveway last summer when we were photographing my new book “STEAM Lab for Kids: 52 Creative Hands-On Projects for Exploring Science, Technology, Engineering, Art and Math”
With a few supplies from your junk drawer and a few inexpensive tech supplies available online, kids can easily make their own CD Bots! Grab a copy of “STEAM Lab for Kids” for easy instructions, or figure out how to do it yourself by attaching a toy motor (connected to a battery) to a CD with toothbrushes glued to the bottom!
