small battery How to Make a BristleBot

They're robot bugs.You open them and they go.But before hexbugs appeared, there were also Bristlebots.Bristlebots are made from the end of the toothbrush with a connected vibrating motor and battery on it to drive it.It looks simple, but when you see your bristlebot bustling across the table, you can't help but grin.
It seems to me that BristleBots are more fun and cool than hexbugs because they are a project that you can do and improve on your own.You can make a BristleBot for less than $5 and it will be much cheaper if you buy the material in bulk.The advantage of BristleBot is that you have to make it work with your material.
Only you are using the toothbrush and cut into that position with the motor and battery.You may just have to use your noggin to get it to work.It is crucial to keep it light in weight, so you will want a small battery (not AA ).
A round batter (such as a coin or watch battery) will give enough power to run the robot.The magic of Bristlebot comes from the vibration motor.The vibration motor (also known as the pager motor) is called the eccentric rotating mass vibration motor.
The ERMs has an asymmetrical weight that rotates, causing the motor to move unbalanced.For projects that are creative like this, there is no real right or wrong item to choose from.I really recommend buying a couple to play.
Having a different model of motor allows you to play with the impact of weight on the robot and how to install the robot.Because these small motors can be recycled from many different products (pagers, mobile phones, electric toothbrushes, toys, etc.), there are often good categories on ebay and the price is very low.
As I mentioned, it's good to buy a few different ones so you can try on your bot how they balance in different ways to achieve the best results.I also like to pick cheap toys in the yard sale and reuse these parts.A box of fast food toys sold in many courtyards, 10 cents per box, if you think of them as parts, that's fine!It's a pig bristles after all, so you need some pig bristles.
I highly recommend using a toothbrush with at least some tilt bristles so that your robot moves better in one direction.Some people have mixed some rubber bristles which are also great.Buy a new toothbrush or recycle an old oneJust wash it off first!(Ewwww.
Because you want to keep your bristlebot light (so it's fast), you'll want to use a small battery --1.5V -3V.This should give you enough power to run your little motor and still keep it light in weight.Also, they will have a better balance on your toothbrush head.
If you look around the Internet, you can find a lot of such batteries at a very low price.If you use bristlebots as your course program, it can really reduce the price.I'm usually a group.So you made a robot.Now what?1.Get together with your friends and their bristlebots and see who has the fastest vibrator.
This makes the robot run very straight and does not interfere with each other.You can also try an open area (all together) so that it can test not only the speed, but also its straight line.2.Create a navigation course for your robot.
Consider adding walls, curved walls, etc to your maze, and how long it will take him to get through several times.Maybe race against another robot in the maze3.Decorate your pig stle robot and make it personalized.
.Give them some style.
4.
So, you figured out how to make it better, but how do you make it better?Can you make it faster or more stable?What variables can you change to achieve this?5.Get Creative.Try something different.Add another toothbrush head or add something else-anything.Play it and see what you can do.Try a catamaran style like the one on the left, or add a pencil to track your robot path.
The double sided foam tape will make it easy for the battery and the motor to fit onto the brush.It's much cleaner than sticking, and you can take off your material and use it later.You can tape it, but it's ugly and heavy.If you do this in class, you can also buy longer volumes of this tape.
Bristlebot is a vibrating robot.
Vibrobot is any robot that shakes it using some power and vibration motor (commonly called pager motor.It is the most basic form of the existence of robots.Bristlebot uses the tilt bristles of the brush head to indicate the direction of those jitter and to move the bot in one direction.
When it touches something, it corrects itself and moves in a different direction.Interesting is obvious, but where is the learning to make bristlebots?A child can learn a lot from making bristlebots.First of all, this is a lesson on the following directions and problem solving.
Given a set of basic instructions on what to do, they will have to solve the problem of how to install the motor and battery.If it is not centered, the robot will fall down and they have to figure out how to correct the problem.Electronics -Making bristlebot is a basic course in electronic technology.
In order for it to work, you have to get the wires right.They will learn to understand both sides of the battery to create the circuit-That's simple.Robotics -The British robot is a robot.Simple robots, but robots.What does it take to be called a robot?Why is this eligible?Going Green -Making bristlebot is a simple lesson to reuse and recycle.
If you salvage your materialYou can show the wires of used toothbrushes, mobile phone motors (or old toys, battery operated toothbrushes) and anything --Not just tell, but show-What people throw away is still valuable.Discuss how this can be done on a larger scale.If they can do this with a broken electric toothbrush, what can they do with a broken boat?a broken car?You can do a lot of things.
Experiments you can doWith your bristlebot..Whether you use the sheets or not, it will give you a lot of ideas on how to use bristlebots to teach electronics, scientific methods, center of gravity, and even biology.In my opinion, scientific methods are the best choice.
Once bristlebot is made, ask a question like, "What happens if we add a weight to the top of your bristlebot?Let them make predictions and write them down.Get some start-up information (Control Data), such as the speed of driving along a thin Road.Then add a weight to bristlebots-For example, the coin stuck on itRecord the speed on the path by weight.
Let them compare the results and draw a conclusion.Then discuss why they came to these results
