BristleBot Model 2

Target Audience

• Children (age 8-14)

  

  BristleBot Model 2

• 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
• 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

• 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)

• 
  1) Gather the listed materials
• 
  2) Angle the brush so that the model moves in the forward direction
• 
  3) Attach the metal compartment that can be found inside the $1 Material
• 
  4) Add the wire to the motor
• 
  5) Tape the Battery (Make sure the battery is double sided)
• 
  6) Placing the Battery onto the Motor
• 
  7) Duct-Tape the Battery to the Motor
• 
  8) Attach the Motor to the Brush
• 
  9) Duct-Taping the Wire to function as a switch

Procedure: BristleBot Model 2 (Vids)

• 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

• The demonstration of the BristleBot 2

Pro(s)

• 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)

• 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
