#Robot arm arduino Bluetooth#
This was to speed up tests, and avoid unwanted movement of the arm.A simple Robot Arm with Arduino UNO board and Bluetooth Low Energy The first step was to assemble few cardboards to resemble an arm: 2 joints to emulate elbow and wrist. One is the Vcc, other is the GND, and the third is the SIG pin.

Servomotors are connected to PWM pins of Arduino and the circuit is powered with 12 volt DC adapter. The robotic arm is equipped with Arduino UNO board and a Bluetooth Low Energy shield, with whom receives new servos positions, and a “servo shield” which allows to uncouple Arduino UNO power supply from servos power supply, and so use high torque servos without draining current over the microcontroller’s limit. In the circuit, Arduino Nano is used and Bluetooth module HC-05 is connected to it. The Arduino UNO, on its side, does not have Bluetooth Low Energy communication, so we used an HC-05 module for this purpose.

The Raspberry Pi 3 plays a fundamental role: it runs handle inputs from the human arms, translates it in servos’ positions and then send the new position to the robotic arm. arduino-cli Servoeasing Usage Robot setup. An example client in Python to use as a starting point for higher level behavior. The robot arm uses Moveit plugin to apply kinematics by the KDL solver. These packages were tested under ROS kinetic and Ubuntu 16.04 and it works perfectly on ROS melodic and noetic. We used to control Robot Arm made in Italy Arduino firmware to control a robotic arm such as EEZYbotARM. 0, 1023, 0, 500) / 100.0 //0 - 5 endif 15) ROBOT ARM WITH ARDUNO LASER CUTTING Robot arm construction is one of the basic projects to be learned. Arduino robot arm: ROS packages that can be used to plan and execute motion trajectories for a robot arm in simulation and real-life. Once the construction of the robotic arm is finished, it is time to move on to the electrical connections that require particular attention, especially in the case of motors.
