Attaching the Servo Horns
To begin building the 3D printed robot arm, the first step is to attach the servo horns. This involves taking one of the circular servo horns and pressing it onto the main assembly. The next step is to take the other half of the rotational base and feed all of the servo wires through the hole.
Gluing the Ring and Inserting the Base Servo
The next step is to glue the ring to the base and line up the pin in the front. After that, a piece of clear acrylic is cut to fit in the window and glued on the inside. The base servo is then inserted and screwed down using the four screws in the servo bag.
Attaching the X-Shaped Servo Horn
The x-shaped servo horn is then pressed onto the servo and secured with the screw from the servo bag. All of the servo wires from the main assembly are then fed into the hole and the arm is snapped around the ring that was glued on. The servo wires are then wrapped around the base servo to make sure they are all the same length.
Wiring the 3D Printed Robot Arm
To begin the wiring process of the 3D printed robot arm, one must first secure the bottom board mounting plate, Arduino Uno or Leonardo, and the servo driver module with 8 M2x 4 mm screws. Once this is done, the switch should be pressed into the Music base and a female T plug connector should be glued to the base. The positive side of the female connector should then be soldered to the switch. To ensure flexibility, a smaller wire should be soldered to the ground pin of the T plug.
Connectors
The next step is to glue one four pin connector and one three pin connector on top of each other and press them into the hole. This should be done on the back cover Music panel. The controller should then be built according to the wiring diagram located below the Subscribe button. All of the potentiometers should be mounted using a washer and a nut, and the parts should be press fit onto the potentiometers.
Switch
The switch should be connected with one ground pin and one signal wire. The ground pin from the switch should be connected directly to the closest potentiometer Ground Terminal. The signal wire from the switch should then be connected to the connector.
Servo Driver Module
The servo driver module should be connected to the Arduino Uno or Leonardo. This can be done by connecting the signal wire from the servo driver module to the digital pin of the Arduino board. The ground wire should then be connected to the ground pin of the Arduino board. The power wire should be connected to the 5V pin of the Arduino board.
Potentiometers
The potentiometers should be wired in series. The first potentiometer should be connected to the ground wire and the signal wire should be connected to the second potentiometer. This should be repeated until all of the potentiometers are wired in series. The last potentiometer should then be connected to the signal wire of the servo driver module.
Final Steps
The last step is to connect the servo motors to the servo driver module. This can be done by connecting the signal wire of the servo motor to the signal pin of the servo driver module. The ground wire should be connected to the ground pin of the servo driver module. The power wire should be connected to the power pin of the servo driver module. Once this is done, the 3D printed robot arm should be ready for use.
Connecting the Potentiometers
The next step is to connect the potentiometers. The positive pin of the potentiometer connects to the positive terminal of the next potentiometer, and the ground pin connects to the ground terminal of the next potentiometer. The middle signal wire of the potentiometer is then connected to a pin on the connector. This process is repeated for all the potentiometers, and the ground and positive wires from the last potentiometer are connected directly to the connector.
Connecting the Plug
The plug is a four-pin connector glued on top of a three-pin connector, resulting in seven pins. One of these is the ground, one is 5 volts, and the rest are signal wires. The wiring diagram in the description can be used to identify where the servos plug into the driver.
Attaching the Back Cover and Bottom Plates
The back cover is slid through the opening and then closed with the bottom plate. The back cover and bottom plate are attached with four M2x4mm screws. The two stabilizing feet are mounted using two M3x8mm screws.
Disengaging Motors
Before uploading the code, it is essential to ensure that all the motors are disengaged and can move freely. To do this, check that all the servos can move without any impediment. Additionally, the middle gear of the wrist servo should be removed and the base of the servo horn should not be pressed onto the servo.
Uploading the Code
Once the motors are disengaged, the next step is to upload the code. To do this, plug in the Arduino, power, and controller. Make sure that the controller is in the starting position and install the library. After the library is installed, press verify and then upload the code. All the servos should move to match the potentiometers without actually moving the arm. Once the code is uploaded, unplug the Arduino and turn off the power.
Reinstalling Components
After the code is uploaded, it is time to reinstall the components. Reinstall the middle gear on the wrist and reinsert all the servo horns onto the servos. Attach the two rotating base halves using two M3x 8mm screws. Finally, glue the cover over the gears.
Gathering the Materials
For this tutorial, you will need a 3D printer, Arduino board, servo motors, and a few other materials. The 3D printer will be used to print the robot arm parts, while the Arduino board will be used to control the servo motors. The servo motors will be used to move the robot arm. You will also need some wires, a power supply, and a few other materials.
Printing the Parts
Once you have gathered all the materials, you can start printing the parts. You will need to download the 3D model of the robot arm from the internet. Once you have downloaded the model, you can use your 3D printer to print the parts. Make sure to follow the instructions carefully and print the parts with the highest quality settings.
Assembling the Parts
Once the parts have been printed, you can start assembling them. Start by connecting the servo motors to the robot arm. Make sure to connect the servo motors to the correct pins on the Arduino board. Once the servo motors are connected, you can start assembling the robot arm. Make sure to follow the instructions carefully and use the correct screws and nuts.
Programming the Arduino Board
Once the robot arm is assembled, you can start programming the Arduino board. You will need to write a program that will control the servo motors. The program should be able to move the robot arm in different directions. You can find tutorials online that will help you write the program.
Testing the Robot Arm
Once the program has been written, you can start testing the robot arm. Connect the power supply to the Arduino board and turn it on. The robot arm should start moving in the directions that you programmed it to move. If the robot arm does not move, you may need to check the connections and the program.
This tutorial has outlined the steps necessary to build a 3D printed robot arm using Arduino. The process involves attaching the servo horns, gluing the ring and inserting the base servo, and attaching the x-shaped servo horn. Once these steps are completed, the arm is ready for use.
