Art Bots or Scribble Bots are great fun to make and provide lots of investigative opportunities. This simple version uses a small motor and pens fixed around a pot. The motor makes the arm ( glue stick ) spin, which in turn makes the Scribble Bot move.
Pupils could be given a challenge, such as getting the Scribble Bot to draw a dotted line or left to explore freely going through an iterative process of designing, testing and amending their ideas.
How to make an Art Bot
Scribble Bot Materials
Thick elastic band 2 in x ½ in
Pringles can or other small container
Instructions for making a scribble bot
Place the thick elastic band around your battery and sellotape it to the top of a pringle can or similar shaped container.
Attach the motor to the top of the container, it needs to be close to the edge so the arm can spin freely.
Attach the leads to the motor and battery. The elastic band is perfect for holding the leads in place at each end of the battery as they can easily be removed to turn the motor off.
Attach a glue gun stick to the motor and test to make sure it spins.
You can experiment with different length glue sticks, or other items such as corks or even plasticine.
Attach 4 felt tip pens around the sides.
Remove the lids and let your Scribble bot loose on paper.
More Art Bot Activity Ideas
Experiment with different types of mark making materials:
Experiment with different materials on your motor as the arm
- Different lengths of glue stick
Investigate what happens if you move the arm off centre, we added a piece of K’nex to the one end of the cork in the picture above which made a dotted line. A central arm made a smooth line.
Placement of the pens
Try the pens higher and lower and investigate how this changes the drawing.
Could you add a trailing pen behind or to the side of your scribble bot?
Can you add a switch or buzzer to your circuit?
