I have Phantomx Pincher arm connected to the computer via FTDI USB cable. I clone arbotix_ros and I did catkin_make properly. BUT I can not detect my servos (dynamixel ax-12a) thru arbotix-m, I am getting the following output, anyone can help me please ?? I even tried arbotix_gui I got the window but the servos don't move. |
| 2019-05-20 01:52:32 -0500 | marked best answer | Difficulties in visual tracking in Ros-by-example book Hi Rossers I am stack over the flow, I need help plz, I don't know where I am mistaken. I have Phantomx pincher robotic arm (with 5 dynamixel 12ax servos) connected with arbotix-m board, I am using ros indigo. I am following this ros-by-example tutorial and this repo. In order to control the first servo (id = 1) based on the motion of coloured object that should be detected by webcam. I want the servo's id 1 rotate when the object is not in the centre of x-axis. For now, I want to get one servo rotating first, then I will consider y-axis for another servo. The tutorial explains how to control the motion of the pan and tilt head servos. I am trying to consider the pan servo with my first servo. I did the following :- 1- To get the video stream and detect the object based on colour and send the topic 2- To fire up the arbotix-m, I can also see the arm in rviz, and I can move the servo (id 1) individually 3- To launch the head tracking node (which should be my first servo tracking node, since I consider the I got this out put When I run And my first servo is not moving, I do not know where I am mistaken, what to check with the third step as I mentioned above, I guess there's some thing wrong there. Please tell me !! |

| 2019-03-01 12:37:56 -0500 | marked best answer | How to use ViSP example for visual servoing ? Hi ROSSER I have been struggling for a while with this issue, I want to do visual servoing with real UR5 arm, I can control UR5 with ur_modern_driver properly and I can use I prepared a ROS node that can subscribe to the published pose, but I do not know how to use PBVS or IBVS (ViSPexamples) ???, and then publish the velocity to the UR5 driver ???. I can run this PBVS-example alone (which can calculate the errors and camera velocity) but I don't know how to feed it with my real QR-code. I also spent time with pioneer-example, but this is only for mobile robot, I couldn't use it for UR5 arm. I mean, it gives linear and angular velocity, but I need the position and orientation for the end-effector of the UR5. The part the I am stuck is, I don't know how to feed PBVS-example with my real QR-code (see below) in order to calculate camera velocity based on my real input. Thanks in advance This is my ROS node |
