Making own Microbots

Hello, people today in this blog we are designing the microbots from the movie Big Hero 6, Micro bot is technically a noun for small mobile robots, Micro bots in the movie were micro-sized robots capable of forging together to manifest themselves in whichever shape or function the creator has the mental capacity to command via the neural-cranial transmitter. Here you will ask me when we started doing impractical stuff.

Hold your horses we did projects with our twist and twirl, just like the other projects we are going to accomplish this project.

The twist in this project is rather than controlling the bots with the neural transmitter we will let them travel and connect as they want. This ain’t sci-fi this is an easier cheaper, and least complex design, So let’s start making our super cool micro bots on budget, First, we are just making the bots that can sense where the fellow bots are, and reach them. Later when adding computer vision and AI its application will be limitless.

Starting with selecting the components, we need a small and usable microcontroller that would be AT tiny 85.

AT tiny is having 6 input output pins which is exactly how much we want, moving further we are adding servo motors for the robot to travel, the next part is a Bluetooth module, which we are using to find the distance between the robots, if you are using a development board in which you get an embedded Bluetooth module then you don’t need any external module for that, Now the main component that will give the superpower to our microbot which was shown in the movie that is bots getting attach for that we need electromagnets, there are few electromagnet modules out in the market which you can use according to your budget.

Now moving further toward calibration connection and schematics.

For coding

• pair the Bluetooth modules via hard coding
• Use the RSSI function and store its value in a variable,
• After that code for the servo motors
• Create two functions that allow bots to move forward and backward
• You can also add the motions for the motors to turn left and right.
• Calibrate the motors accordingly
• Now check the value of RSSI stored in the variable
• Check the RSSI value when the bots are 5–10 CMs away from each other
• Use the value of as a base value and if the value changes and increases code the robot to move accordingly and come back closer to the fellow bot
• And when the fellow bot is in the range turn on the electromagnet so that stick together.

For schematics and circuits.

• Place the Electromagnet at the center of the bot.
• place the servo at the ends of the servo horns facing outside.
• Use a Mini breadboard or the zero PCB and soldering to complete the connection of the components.
• Upload the code and use copper tape and tape the circuit to avoid any harm from the EMF of the electromagnet.
• One can use Insulating tape and then wrap the foil over it so the foil will absorb as much as it can and then the rest of the un absorbs EMF is reflected by the insulating tape
• After completion of the circuiting and connections add 3D printed or handcrafted shafts for the legs of our bot and give our bot a body

When done with this Ta Daa! your Microbots are ready to connect the batteries, Keep the at distances and watch them coming closer

That is all for this blog, keep innovating and learning,

Do give your suggestion for the next Bot or the title of the Blog,

So until next time. Take care
