BristleBot Model 3

Target Audience

 * Children (age 8-14) BristleBotModel3.jpg
 * 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
 * Improvements from the previous BristleBot Models
 * The balance issue has to be accounted
 * Maintain the safety rules as BristleBot Model 2 centered on
 * Like BristleBot 1, the model must be appealing to the eyes of children

Materials

 * 5 in. by 5 in. wooden block
 * Three $1 material's brushes
 * $1 material's motor
 * Two 3 in. metal strings
 * Duct Tapes (Grey and Orange Colored)
 * Not mandatory to have separate colors but it looks nicer this way

Procedure: BristleBot Model 3 (Vids)

 * | Step 1: How to Assemble Model 3's Base
 * | Step 2: How to Attach Metal Strings on to the Motor
 * | Step 3: Attaching the Motor to the Wooden Block
 * | Step 4: Duct-Taping Battery onto the Wooden Block
 * | Step 5: Duct-Taping Metal Strings onto Battery

BristleBot 3 Testing

 * The demonstration of the | BristleBot 3

Pro(s)

 * Significantly safer model compared to the BristleBot Model 1
 * No sharp needles or dangerous materials required
 * 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 = Wooden Block
 * Top = AA Battery + Motor
 * Duct tape is flexible yet relatively durable to stay attached to the model
 * It can also be easily cut with scissor
 * Relatively simple and easy to make
 * The cutting parts for duct-tapes can be done faster under adult supervision
 * No complex or tedious coiling of wires required to attach them to this model's motor
 * Portrays an image of a tank
 * Children might find this model appealing to their eyes
 * Relatively creative external features
 * Stable and the model doesn't fall to one side
 * Unlike the BristleBot Model 2, prior to the motor activation, the model doesn't fall down to the ground

Con(s)

 * Exposure of vibrator
 * As the vibrator spins to cause movement, children's hair (especially girls') could be rolled up
 * The model lacks mobility
 * Cannot move unless the user constantly hold onto the wires firmly
 * When let go, the model almost immediately shuts down
 * There is no 'real switch'
 * Duct tape may have been used to attach the wire onto the battery but it peals off eventually
 * Can only 'move' or 'function' if the holder consistently presses the wire onto the battery
 * Frustrating for the young children due to its limited ability to move
 * As seen in the video, occasionally, despite pressing onto the battery, the model doesn't function
