# 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
