BristleBot Model 4

Target Audience

• Children (age 8-14)

  

  BristleBot Model 4

• Adults (parents/guardians)
  • Who would accompany the children to replicate this model

Starting Point

• 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

• 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
• 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
• Transcend the previous Models' concepts
  • Safe but stable model
  • Easy to assemble but creative model

Materials

• $1 material's base
• $1 material's motor
• Three brushes
• Double-sided foam tapes
• AA Battery

Procedure: BristleBot Model 4 (Pics)

• 
  1. Gather the listed Materials
• 
  2. Tapes are cut-out based upon the length and width of the brushes
• 
  3. Attach the tapes onto the brushes
• 
  4. Place the motor back inside the Base model
• 
  5. Once the motor is held inside, put AA battery as well as its cap on, closing all together
• 
  6. Place double-sided tape onto the third brush
• 
  7. Position each base onto the base of the model. Two brushes are facing at the same direction whereas the other one is located in the center, facing away
• 
  8. After a trial and identifying the model's misdirection, reposition the brushes to correct its directional movement
• 
  9. Final Product of the BristleBot Model 4

Procedure: BristleBot Model 4 (Vids)

• Step 1: Adding double-sided tapes onto brushes
• Step 2: Reassemble the motor into the base model
• Step 3: Attach the brushes onto the base model
• Step 4: Place double-sided tape onto the third brush and attach it onto the other end of the base model
• Step 5: Run the current model. If the angle is off (as shown in the video), reposition the brushes so that it moves forward direction
• Step 6: Repositioning the brushes

BristleBot 4 Testing

• The demonstration of the BristleBot 4

Pro(s)

• Safe and no exposure of vibrator
  • Children with long hairs do not have to worry about being coiled onto this model
  • No sharp materials, such as needles or knives were used
• Potential creativity
  • Because the external features of the model is plastic, children can draw onto their finished product
  • Stickers and art supplies could be prepared if this model is chosen for the MakerFaire
• Assembly style to create this model
  • Each compartment could be replicated by young children by simply stacking each layer on top of each other
    • Bottom = Toothbrushes
    • Middle = Double-Sided Tapes
    • Top = The entire electronic tooth brush without the brush (just its base)
• Requires so little time to replicate this model
  • Saves lot of times for adult supervisors and children to make this model and continue the tour on MakerFaire
• Actual 'Switch' button
  • Doesn't require users to find ways to attach the free-floating wires onto the battery
  • Uses 'on' and 'off' switches to activate or turn off the motor

Con(s)

• Tedious when it comes to repositioning of bottom brushes
  • It takes just as must time replicating as repositioning the bottom brushes
• Doesn't necessarily go 'straight'
  • There is a trend of forward motion; however, the model moves diagonally not straight
• Design, in general, is not too appealing but rather dull
  • Decorations can be added but the structure might be plain in the eyes of children
