# 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
