  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

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.
