remote controlled crane from aakash karekar on Vimeo.

IT'S BASICALLY A SMALL CRANE WHICH IS OPERATED VIA REMOTE CONTROL(RF CIRCUIT).THIS CRANE HAS TWO FUNCTIONS i.e1) IT CAN ROTATE 360 DEGREE.
2) AND LIFTING FUNCTION.
THE WHOLE CRANE IS MOUNTED ON A VERY RIGID METAL BASE ALONG WITH MOTOR(VCR HEAD) FOR ITS ROTATION.

Step 1: THINGS YOU WILL NEED

  1. AQUAGUARD METAL BASE(ANY STRONG BASE WILL DO)
  2. VCR HEAD
  3. MECHANIX SET
  4. 2 TAPE RECORDER MOTOR
  5. 2 RUBBERBANDS
  6. 2 RC CIRCUITS FROM TWO SIMILAR CAR AND ANY ONE OF ITS REMOTE
  7. NUTS AND SCREWS
  8. TWO 6V BATTERY OR 6V DC POWER SUPPLY

Step 2: CRANE BASE

THE ABOVE IMAGE SHOWS A BLUE COLOUR METAL BASE UPON WHICH THE WHOLE CRANE IS MOUNTED.THAT BASE I FOUND FROM OLD AQUAGUARD(WATER PURIFIER MACHINE).FOR FIXING ALL THE MOTORS AND PARTS ON IT,I HAD TO DRILL HOLES ON THE METAL BASE ACCORDING TO THE POSITION OF MOTORS AND PARTS HAD TO BE FIXED.

Step 3: ROTATION OF CRANE

A TAPE RECORDER MOTOR WAS USED TO MAKE THE CRANE ROTATE .THE MOTOR WAS CONNECTED TO ANOTHER MOTOR(VCR HEAD)BY RUBBER BAND.

Step 4: MOTOR HEAD

AFTER FIXING ALL THE PARTS AND MOTOR,AGAIN I HAD TO MOUNT ANOTHER MOTOR,WHICH I FOUND FROM OLD VCR(VCR HEAD) UPON WHICH THE WHOLE UPPER PART OF THE CRANE HAD TO BE FIXED.

Step 5: UPPER PART OF CRANE

FOR BUILDING UPPER PART OF CRANE,I MADE USE OF MECHANIX GAME SET.IN THAT GAME I FOUND MANY STEEL PLATES,WHICH MADE MY WORK EASY FOR BUILDING THE UPPER PART OF CRANE.
IT ALSO MADE CRANE LOOK VERY SYMMETRICAL AND RIGID.

Step 6: INTERWINING OF CORD

AFTER COMPLETING THE UPPER PART OF CRANE,I FIXED THE MOTOR,THAT I GOT FROM AN OLD TAPE RECORDER TO A PULLEY BY RUBBERBAND.THAT PULLEY WAS WINDED WITH ALMOST 2 METER CORD.
THE MOTOR USED TO WIND IN AND WIND OUT THE CORD,WHEN IT USED TO ROTATE.
WITH THIS MECHANISM,THE HOOK WHICH WAS ATTACHED TO END OF CORD WOULD SLIDE DOWNWARD AND UPWARD.

Step 7: RADIO FREQUENCY CIRCUIT(RF CIRCUIT)

TO MAKE THE CRANE OPERATE VIA REMOTE,I TOOK TWO RF CIRCUIT FROM TWO SIMILAR RF CAR.
ONE RF CIRCUIT I CONNECTED BELOW THE METAL BASE FOR ROTATION OF THE CRANE AND ANOTHER RF CIRCUIT WAS CONNECTED TO UPPER PART OF CRANE FOR MOMENT OF CORD UP AND DOWN.
5V TO 6V WAS GIVEN TO IT AS INPUT VOLTAGE.

Step 8:

<p>you assemble carene forward backward systom no nah so you want bend a little crapes upper part and not to weight too on the upper part or it will fall</p>
<p>but where is a security of crane i mean if the crane is working and suddenly its screws were loose so what you managed for it</p>
<p>I&rsquo;m working on a project which is about making a rescue <br>robot . I have struggling with it for 4 months and now all the mechanical works <br>had been done . but I&rsquo;m facing difficulty in make the robot to work with rf <br>module can u plzz help me&hellip;</p><p>I want make transmitter and receiver that can control the <br>motion&hellip;I mean that receiver should have control 8 dc gear motor and each dc <br>motor should have a forward and backward botton to control the motion &hellip;&hellip;can u <br>kindly help me with this project &hellip;.if u can make the circuit board diagram for <br>the PCB &hellip;.or any other suggestion plz reply&hellip;&hellip;mail me at &ldquo;sunny1995gagan@gmail.com&rdquo;</p>
Good work I also built something like this. Suggestion: Try to build this thing on another rc car n then it would be a great crane
