As far as I’m concerned, you’re never too young to start mixing art with robotics.
So, next time you and your budding young tinkerers need something to do on a rainy day, you should have no trouble scraping up the parts to put together this crude, drawing robot project that we saw at the Seattle Robotics Society Robothon.
Your blog shows the ArtBot that FIRST Robotics Team 1318 was selling at Robothon. You call it a “Kid’s Draw Bot.”
First of all, I’m not sure that it’s really ethically correct for you to take someone else’s idea and publish it. We originally saw the ArtBot at PDXbot in Portland, and asked for permission from them before using their design.
Secondly, it would be nice if you gave credit to our team for the idea. There is no mention on your blog that the kits and instructions were created by our team. Our student team members worked hard to create the kits, soldering battery pack leads to the motor, creating instructions, and putting the kits together. It is a shame that you chose not to recognize their efforts.
No harm meant. I wasn’t trying to own the design, just share it. I looked to see if I could find this project documented anywhere on the Web, but I couldn’t, so I just linked to the SRS Robothon site when I gave credit in my post.
Thank you for helping clear this up, and thanks to the FIRST Robotics Team 1318.
Also, please pass my thanks along to the Portland team that you originally got the idea from.
Supplies for the
Draw Bot ArtBot:
- A paper cup
- Duct tape
- 3 felt-tipped pens
- 2 AAA batteries
- 1 small toy motor
- Small metal weight (nut)
- Switched battery holder (optional)
You should be able to pirate the motor, wires, switch and battery holder from some toy that you’ve either broken, out-grown, or never really liked in the first place. If not, you may have to dash out to Radio Schack for those, or just tape the motor wires directly to the battery terminals and forget the switch and holder.
Put it together
Assemble the parts as shown in the above photo.
- Tape the motor to the battery/switch assembly.
- Duct tape a small weight to the shaft of the motor (offset to one side)
- Tape the motor assembly atop the inverted cup
- Attach the felt pen “legs”
Remove the pen caps, set the robot down on some paper and connect the power. The eccentric weight on the motor shaft will cause the whole thing to vibrate and “walk” around on the paper.
Harlan testing the draw bot.
You can adjust the line smoothness by trying different rotor weights and weight positions. The path that the bot takes can be adjusted by changing the angle of one or more of the pens. Once you get it dialed in, you can make some neat patterns.
No, you’re not going to want to keep any of the crap that this thing draws, but the point here is engagement, and on that front the draw bot project is a keeper.
