New and Improved Art Bots

After making some modifications to their original Art Bots, the boys came up with a design that fixes the two biggest flaws.

The first big flaw was that the wires would get tangled in the “feet” of our bot causing it to tip over. Oh, the frustration. We tried tape and rubber bands with minimal success. In the new design, you just stuff all of the battery pack and wires into the cup and problem solved!

The second problem was the stability. The markers are easier to tape onto the container than they are to foam. The design also allows for enough wiggle to make the bot fun, but not so much that it falls. You can see that we needed to add a popsicle stick to support the motor.

I would love to see any variations your kiddos come up with!

If you haven’t already, you should absolutely sign up for Supercharged Science’s mailing list for all sorts of FREE instructional videos. I have never gotten an email from Aurora that was junk, they truly are an awesome company with a great philosophy….no pressure to buy anything…e.v.e.r. All Aurora's videos have useful information and great video links to make cool projects like this!

Art roBots!

Science + Art = BIG fun!
These wiggling, jiggling robots have been a HUGE hit at our house this week.

Making an Art Bot is super simple!

You'll need:
1 clothes pin
1 1.5-3 V DC motor (these can be found at Radio Shack for about 3 bucks)
1 Old plastic cup (the kind they put drinks in at a restaurant) or a Foam block
1 Battery pack that holds 2 AA batteries
2 AA batteries
2 Alligator clips with wires
some old markers
Hot glue gun
Tape

Step 1: Hot Glue the clothes pin to the motor. Make certain not to glue the shaft to the motor case. Just give the shaft a turn or two while the glue is drying and it should be good.

Close up of the clothes pin attached to the motor shaft.
Step 2: Glue the motor and battery case to the foam block or top of the plastic cup. Once you get your Art Bot all set up, you may want to change the positions of these. No problem, rip them off and move them around!


Here you can see how the entire top of the bot is put together.

Step 3: Connect one side of one battery case to the motor and then connect the other side to the battery case wires. Repeat on the other side. This is a good time to pop the batteries in and see if your bot works!
Step 4: Attach the pens. We used tape so the boys could easily change them around, but you could use hot glue or simply just shove them in the foam.
Step 5: Lay out a big sheet of paper and let your Art Bots go free!
