Children (age 8-14) Adults (parents/guardians) Who would accompany the children to replicate this model 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 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 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 1) Gather the listed materials 2) Position three brushes onto the Wooden Block. Make sure the head of two brushes point at the same direction whereas middle one is facing opposite direction 3) Duct-Tape the brushes onto the block of wood 4) Duct-Tape the other end to secure the brushes' stability onto the block of wood 5) Add the two 3 in. metals on the Motor 6) Duct-tape the Motor onto the wooden block 7) Duct-Tape the battery onto the block behind the motor 8) Duct-Tape the Wires onto the sides of the Battery 9) Duct-tape the rear of the model, firmly attaching the wooden base onto the battery 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 The demonstration of the BristleBot 3 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 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
