Hello everyone, I’m new in robotics and working on ROS for pick and place 6DOF robotic manipulator, I m using ROS neotic to run my simulation of robotic arm. I simulated the robotic arm by using URDF in gazebo and RViz. when i run it, it works in RViz and parallel i can see the movements in gazebo. So after this i want to control my physical robot with this simulation like i want to control my robot through this created simulation. I have robot based on servo motors MG996R and i am using this with Arduino nano. So i need to build the hardware interface, i tried a lot but i couldn’t successed. So guide me please how i can do this. Thank you in advance.
