We do that using the write() function which simply moves the servo to any position from 0 to 180 degrees.
In the setup section we need to initialize the servos and the Bluetooth module and move the robot arm to its initial position. String dataIn = "" Code language: Arduino ( arduino ) SoftwareSerial Bluetooth ( 3, 4) // Arduino(RX, TX) - HC-05 Bluetooth (TX, RX) int servo1Pos, servo2Pos, servo3Pos, servo4Pos, servo5Pos, servo6Pos // current position int servo1PPos, servo2PPos, servo3PPos, servo4PPos, servo5PPos, servo6PPos // previous position int servo01SP, servo02SP, servo03SP, servo04SP, servo05SP, servo06SP // for storing positions/steps int speedDelay = 20 Flexible Robotic Arm: Gripper opens to 3.54 inches and 260 degrees, radial wrist motion of 180 Degree, an extensive elbow range of motion of 180 Degree, base. The user needs to wear a glove which consists of transmitter and sensors like IR sensor. Robotic arms are easily programmable and can be given commands to perform certain specific operations. Then we need to define the six servos, the HC-05 Bluetooth module and some variables for storing the current and previous position of the servos, as well as arrays for storing the positions or the steps for the automatic mode. Gesture controlled vehicle is a type of robot which can operated by human hand movements. A robotic arm is a robotic manipulator made by drawing inspiration from the structure of a human arm.
#RESISTANCE BAND ARDUINO ROBOTIC ARM INSTALL#
Both of these libraries are included with the Arduino IDE so you don’t have to install them externally.
#RESISTANCE BAND ARDUINO ROBOTIC ARM SERIAL#
So first we need to include the SoftwareSerial library for the serial communication of the Bluetooth module as well as the servo library. And at the end of this article I will post the complete source code. They are usually available in two sizes 2.2 inches and 4.5 inches. Arduino Robot Arm CodeĪs the code is a bit longer, for better understanding, I will post the source code of the program in sections with description for each section. The flex sensor resistance changes when the sensor is bent. In this proposed system, an Arduino Mega microcontroller gets the information from all the sensors and correctly manages the servomotor with the help of the value of sensors.

So once we have connected everything together we can move on to programing the Arduino and make the Android app.
The power source must be able to handle at least 2A of current. For powering the servos we need 5V, but this must come from an external power source because the Arduino is not able to handle the amount of current that all of them can draw.
