Target Audience[edit | edit source]

  • Children (age 8-14)
    BristleBot Model 2
  • Adults (parents/guardians)
    • Who would accompany the children to replicate this model

Starting Point[edit | edit source]

  • Get a feel for visual conception through this Youtube Tutorial Video
    • This helps to capture an image of a generic BristleBot Model
  • Derive the features for the BristleBot from |Hexbugs

Replication Goal[edit | edit source]

  • Instead of copying the Youtube Bristlebot, remodel its structure and design based upon the listed materials
    • Be creative to gain children's attention and their interests in making this bristlebot
  • Eliminate much materials required from both Youtube BristleBot and BristleBot Model 1
    • Take out dangerous tools or compartments required for this model
  • Like nano hexbugs, the replicated model must move as well
    • The vibration caused by the model allows the Bristlebot to move in a direction
    • Angle the brush/base so that the model moves forward; not in a loop of random directions

Materials[edit | edit source]

  • Duct Tapes
  • $1 material's motor
  • $1 material's brush
  • $1 material's metallic compartment
  • Double-sided foam tapes
  • Wire (Obtained in the Engineering Lab)
  • AA Battery

Procedure: BristleBot Model 2 (Pics)[edit | edit source]

Procedure: BristleBot Model 2 (Vids)[edit | edit source]

  • How to Angle the Brush
  • Step 1: How to Collect Metallic Compartment from the Material
  • Step 2: Attaching the Metallic Compartment to the Motor
  • Step 3: Coiling the Wires to the Motor
  • Step 4: Taping the Battery and Positioning it on the Motor
  • Step 5: Attaching the Wire to the Battery
  • Step 6: Attaching brush to the Motor

BristleBot 2 Testing[edit | edit source]

Pro(s)[edit | edit source]

  • Significantly safer model compared to the BristleBot Model 1
    • No sharp needles or dangerous materials required
    • Metallic compartment is easy to cut even with a scissor
  • Assembly style to build this model
    • Each compartment could be replicated by young children by simply stacking each layer on top of each other
      • Bottom = Toothbrush
      • Middle = Motor
      • Top = AA Battery
  • Relatively simple and easy to make
    • No complex or tedious coiling of wires required to attach them to this model's motor
  • Duct tape is flexible yet relatively durable to stay attached to the model
    • It can also be easily cut with scissor

Con(s)[edit | edit source]

  • Exposure of vibrator
    • As the vibrator spins to cause movement, children's hair (especially girls') could be rolled up
  • The model lacks creativity
    • Because safety had been the central point of the model, the outcome of such design not might be appealing to the children
    • No stickers or even paints can be added to the model
  • The battery life is longer and 'proper' but lacks stability
    • As seen in the Testing Video, BristleBot Model 2 constantly falls to one side
    • Standing battery causes the model to lose its balance
  • There is no 'real switch'
    • Duct tape may have been used to attach the wire onto the battery but it falls off eventually
    • Doesn't solve the balance issue
    • Can only 'move' or 'function' if the holder consistently presses the wire onto the battery
