Instauratio: Wholly Scratch Built Tricopter

Howdy all. Hope you know about Drones aka multirotors.

Now nigh of United States of America know that these flying machines are smooth cossstttlyyyyy.

Indeed i definite to find ways to make em cheap and fast and efficient.

So heres the equation. Less motors = Less ESC = Less price.

Regrettably less motors mean MOVING PARTS.

quadcopters are quiet costly, Dualcopters are overly lentissimo and plain boring.(apologies to those WHO the likes of them).

Sol i built a Tricopter. Its fast carries just enough to support your fpv system and is cheap.

I got mine well-stacked for around 100 USD or 6000 Rupees.

Asset i give also made my own flight controller that rather reduces the toll.

If you like it pleeeasssse vote in the arduino everything contest.

Step 1: Gather Em Up!

3x ESC's

3x Propellers (7x3.8)

3x Brushless Motors

1x Arduino Mega 2560, 1280 or ADK

1x Lipo battery. Suggested 25c 3000 mah but i did'nt have one.

Adafruit Motor Shield Strictly OPTIONAL....... Only for spacious Wiring.

Mpu 6050

Baseplate. (just any strong piece of hdpe operating theatre atomic number 13 with holes in it.)

Woody Booms, Aluminum Boooms, Carbon character (YOUR CHOICE) Suggested Aluminum

Screws nuts and bolts not in pics.

Twist ties non in pics

Female to male wires and antheral to male and female to female wires not in pics

Metal Gear servo not in pic

Long nail not in pics

And of of course a Lone-Star State and Rx.

Step 2: The Frame Contruction

Screw on the baseplate and the wooden frame ( a wearing apparel hanger in my case.)

You should arrest something like-minded it is in the second motion-picture show.

The length of the arms is preferrably 15 cm.

Step 3: The Spinal column Leg

Drill finished the back leg.

So bolt it onto the baseplate.

Your Tricopter frame moldiness feeling something like-minded it is in pic 2.

Step 4: Yaw Mechanism

Arguably the backbone of the tricopter. The yaw mechanism was quiet hard to glucinium honest.

I experimented so many an unlike designs when i knew all it takes is a rotating shaft and a base attached to a servo.

So heres my own yaw.

So what i did was that i hammered a sail through through a piece of wood.

Utilised a rusty cycle spoke arsenic pushrods.

attached the push pole onto the servo horn

bespoken the servosystem at the very back off end of the tricopter

and past i hammered the nail into the wooden boom i was exploitation Eastern Samoa the back leg.

so information technology (the base) tilts as the servo rotates.

The video shows how it works. Good-for-nothing for the coughs :)

Footstep 5: Midway Through

Sol your tricopter should count wish this.

now our concentration will shift from the mechanically related part to the electronics.

Step 6: Motor Climb.

As simple as it sounds know the motors onto the frame.

Do this on all 3 sides.

IT should look on somewhat similar to flic 2.

Step 7: Attach the Props

All you necessitate to do is tie props.

All should be CW props or those without R written on them.

Step 8: Attach the ESC's

The esc's are a very world-shattering part of this build. They convert DC current from battery to actinium current for the motor.

They will make the motors produce the beeping sounds and drive them and configure endpoints.

All you need to do is magnetic tape them onto the framing.

Remember solder bullet connectors onto your esc's. They are really useful, I will excuse in the next step.

Step 9: Connect Your Causative to the ESC

Bear in judgement that there is no order in which you tie in the 3 wires jointly.

Just touch base them and see in which focusing the air is blowing.

If information technology blows down No trouble if it blows sprouted Contrary ANY cardinal wires and it volition be correct.

Use male bullet connectors on the motor and female on the esc.

I used 3.5 millimetre bullets. 9 pairs.

Step 10: Power Distribution

Today for power distribution.

Use wires thick enough to hold the current you will be overtaking through it.

if you victimised xt60 connectors. Use male connected the esc side (the ane with ii poking outward)

so connect 1 male to the shelling.

This male header is connected to 3 female headers using 3 wires soldered into the connector.

Pictures speak more than.

Now just discharge information technology through your frame.

Step 11: Flight Controller

This is the Genius of the tricopter.

The incomparable i made is based on multiwii.

Go to this web site and download the software.

once you have opened the arduino study spell to the tab config.h and if you are exploitation arduino mega take multiwii mega arsenic your flight controller and uncomment tri as your multirotor.

Hera are the connections.

3 Rear
6 Left

5 Right-minded

2 Yaw Servo

Vin to any one of the esc's +ve

gnd to any one and only of the esc's gnd.

then connect all esc's gnd to the arduino's gnd.

the 5v peg of the mpu 6050 to 5v of arduino.

Gnd to gnd of the mpu 6050

scl to scl of mega

sda to sda of the mega.

Recipient throttle to A8

Roll to A9

Pitch to A10

Yaw to A11.

Step 12: Confiscate Landing Gear and Go Downwind.

Now attach the landing gear in my case pvc.

Calibrate your multirotor.

Do the PID tuning or use this setting (works good with well-nig multiritors). P=4 I=0.035 D=15.

Instantly go fly away.

Now i am a good builder but i rather did not get the knack of the flying take off. (Crashed information technology more times than i flew!).

So hope you enjoyed it and were successful with your possess multirotor.
