# BristleBot Model 4: New Edition
## Target Audience

* Children (age 8-14) Previous BristleBot Team's Model
* Adults (parents/guardians) Improved BristleBot Model 4
** Who would accompany the children to replicate this model

## Starting Point

* Get a feel for visual conception by looking at the Previous Team's Model
* Conceptually derive its features but improve upon them for the New BristleBot Model 4

## Replication Goal

* Instead of copying the Previous Team's Model, improve its features for the BristleBot Model 4
* Use similar materials that contributed to success in the Previous Team's Model (especially the use of Velcro)
* Improve upon the Previous Problems that can be identified in the BristleBot Model 4

### Previous Problems

* Tedious when it comes to repositioning of bottom brushes. Its video demonstration: Repositioning the brushes
** It takes just as must time replicating as repositioning the bottom brushes
** The model has to be reactivated again after repositioning
** If there is an issue regarding the repositioning, the entire process has to be repeated
* Doesn't necessarily go 'straight'
** Its demonstration: BristleBot 4
** There is a trend of forward motion; however, the model moves diagonally not straight
** Repositioning wasn't really helpful with this step

## Materials

* $1 material's base
* $1 material's motor
* Three brushes
* Double-sided foam tapes
* AA Battery
* Two sets of Velcro

## Procedure: Improved Bristle Bot Model 4 (Pics)

* 1. Gather the Materials. This time, make sure to include Velcro's in the list
* 2. Attach the Base with the Velcro
* 3. Attach the Velcro to the Brushes
* 4. Attach the Brushes to the Base
* 5. Add and attach the Velcro for the third brush
* 6. Curve the Brushes to promote forward direction
* 7. The final newly edited BristleBot Model 4

## Procedure: Improved Bristle Bot Model 4 (Vids)

* Step 1: Remove the Brushes from the Original Model 4
* Step 2: Attach Velcro to the Base
* Step 3: Attach Velcro to the Brushes
* Step 4: Run the Model 4. This portrays the exact image and movement as the Previous Team's BristleBot
* Step 5: Add the third brush to promote forward direction instead of going in a loop. Be sure to curve the brushes

## New BristleBot 4 Testing

* The demonstration of the Improved BristleBot 4

## Improvements

* The model found its 'permanent' attachments with the use of Velcro.
** This promotes far superior stability than the previous double-sided foam tapes
** The balance issue seems to be solved through its edition.
* Doesn't go diagonally but rather straight motion
** Finally, the model goes in the forward direction
** There is a slight evidence of diagonal motion but this is not as obvious as the previous model
* It's actually much faster than the previous model
** speed wasn't the focus point but it definitely improved
** Won't bore the audience as the model can finally go faster
* Unlike the Previous Team's Model, this Newly Improved BristleBot Model 4 doesn't drift in a circular, continuous pattern

## More Problems

* After a short duration of its activation, the Model moves in a off-course, diagonal direction
** Doesn't maintain its 'forward' motion the whole time
* No creativity in the design still
** Although it wasn't the intention, Model still lacks its creativity in the design.
