Making ROBOT ARMs is very popular and fun among hobbyists, but it's not that easy to control a ROBOT ARM. So today we'll be making a robot arm that can be controlled using just your Android Smartphone or tablet.
Good news is, you just need to program the Arduino, the App is already available to download for free.
Step 1: Parts You'll Need2 More Images
- Servo motor 4x (I'm using micro servo Sg90 but any model or size is okay) you can use upto 5 servo for this robot arm, I've only 4, so I'm using them.
- sliced piece of Card Board - to make the body.
- USB OTG (on the go) [pic3 & 4- all the same]
- And of course a Arduino board (any board)
- And a few jumpers to make the connection
- And a 9v battery to power the servo motors.
Now in here I'm actually making the body in a way so that I can easily connect and disconnect the ARM anytime. Using some pieces of cardboard and Hot glue I've mounted the Servo motors to the cardboard to make the body. It's better to watch the video to better understand how it's done.
Step 3: Making the GRIPPER (finger for Robot Arm)I've made the robot gripper using juice straw or pipe. And added a simple fiver or rope so that when it's pulled the grip will be closed.
Step 4: Assemble the Robot ARMAfter making the arm and making & the gripper you just assemble the body as shown.
Step 5: The CircuitWell the circuit is very easy, you just need to power the servo motors. Arduino will take power from your phone via OTG cable. Don't worry, the power consumption is very low.
Step 6: Download the ANDROID APPSearch on google PLAYSTORE - Servo & Esc controller.
Download from here https://play.google.com/store/apps/details?id=com....
Then Install the app.
Step 7: Programming the ArduinoYou can get the code from the link in the app, I'm providing the code below
//Fuse Batti
Okay download or copy the code from below.
Step 8: Connect the OTG and Arduino to PhoneConnect the OTG cable to arduino programming (USB B) cable and then connect the wire with the phone. The APP will automatically pop up. Click on 'ok' and twill open. After connecting "port open" message will be seen.
Step 9: FinishedAnd you're done, just power the Servo and use the app to rotate every single servo of the arm as you please. So Simple.
Thank you.
