Project 2          Bristle-Bot

 

Bristlebots primary purpose is to make robotics education accessible and affordable. Bristlebots is a way where everyone, both young and mature, can dive into to the world of robotics.

The chances are, you are probably next to a dozen robots right now. Your computer your using right now, the fire alarm above you head, your cellphones are all examples of every day robots that you use to assist you in real life. Bristlebots are introductory level robots assembled using everyday household materials.

Bristlebots is a simple to assemble robot where motion is caused by the transfer of kinetic energy from the motor, vibration, thru the robot to the ground. The bristles rapid motion, from the vibration, enables the robots locomotion.

One of our greatest challenges we face today is improving our nations education standards. Society calls for people with skills to address the increasingly complex needs and issues of society like curing diseases, creating energy, and more. Incorporating Science, Technology, Engineering, and Mathematics to education is the next generation standards. And inspiring student to embrace STEM is part of the process to recovery.

 

Learning Outcomes

•How a motor works.

• To introduce students to electrical and battery safety, electricity, circuits, design, physics & engineering.

•Why the ‘offset’ weight of a pager motor causes vibrations.

•Using the concept of center of gravity to balance the robots.

•Switching the polarity of the battery, will cause the pager motor spin in the opposite direction.

•To introduce students to systematic problem solving

•To encourage teamwork, observational learning, kinaesthetic learning, arts-based inquiry & problem solving

•To encourage creative uses of technology

Directions

  • Design and build your Bristle-Bot

  • Record your fastest time to complete one lap of the track.

  • Measure the Length of the Track.

  • Calculate the average speed of your BristleBot, using the following formula:

 Speed = Distance/Time

  • If the object starts from rest, calculate the acceleration of your BristleBot.

Use the equation:  

 

 

  • Now you know the rate of acceleration you can calculate the final velocity of your BristleBot, using the equation:
