![]() The pick and place actions are performed from the Arduino sketch directly. Apart from the Microcontroller (we have used Arduino UNO) and. This will subscribe to /direction topic and execute motion by using Moveit move group In this project, we have built a simple Robotic Arm, which is fully automated to do certain tasks. (Note: check the camera index and update the script if needed) This will detect blue color and publish the x,y coordinates to /direction topic $ rosrun rosserial_python serial_node.py _port:=/dev/ttyACM0 _baud:=115200 Select the Arduino port to be used on Ubuntu systemĬhange the permissions (it might be ttyACM) The next level up from the Tinkerkit Braccio robot, Braccio++ is a revolutionary new robotic arm designed solely for higher education, including engineering. $ python color_thresholding.py Using OpenCV with the robot arm in ROS In Real Robot If it is not, update line 8 in color_thresholding.py ![]() Run color_thresholding.py to test the cameraīefore running, find the camera index normally it is video0 Pick and place by using OpenCV Preparation $ roslaunch moveit_pkg demo_gazebo.launch Run the following instruction to use gazebo $ sudo chmod +x ~/catkin_ws/src/arduino_robot_arm/robot_arm_pkg/scripts/joint_states_to_gazebo.py Controlling the robot arm by Moveit and kinematics $ rosrun robot_arm_pkg joint_states_to_gazebo.py $ roslaunch robot_arm_pkg check_motors_gazebo.launch Run the following instructions to use gazebo (Note: You may need to use ttyACM) Simulation ![]() $ rosrun rosserial_python serial_node.py _port:=/dev/ttyUSB0 _baud:=115200 You can also connect with hardware by running: $ roslaunch robot_arm_pkg check_motors.launch Usage Controlling the robot arm by joint_state_publisher Make sure to change the port permission before uploading the Arduino code Install the arduino package and ros library The robot arm has 5 joints only 4 joints can be fully controlled via ROS and Rviz, the last joint (gripper) has a default motion executed from the Arduino code directly. $ sudo apt-get install ros-noetic-ros-controllers ros-noetic-ros-control In an ED722C 6-DOF commercial robotic arm was used to be motion controlled. Servo motors: Servos are used to operate remote-controlled or radio-controlled toy cars, robots, and airplanes. Arduino support for Simulink software was proposed to control the hardware. $ sudo apt-get install ros-noetic-gazebo-ros-control joint-state-publisher Wheeled Robotic Arm Using Arduino Controlled Through Bluetooth. $ sudo apt-get install ros-noetic-joint-state-publisher ros-noetic-joint-state-publisher-gui
