We are currently trying to use the camera to complete some basic tasks, but I only find one camera example in the tutorial " camera image display example". If we want to do something more complicated, like camera inspection, or using camera to recognize other targets and send signal to control the gripper. Is there any good example for it that anyone can share? So appreciate! I know Rivz is pretty good software and has a lot of functions, but we are research based and we hope to access basic codes. We are currently doing Linear Temporal Logic, if you have any experience about its application on Sawyer robot or currently doing that too, please provide some advises! Thanks a lot! Junchao Li
Hello everyone, So I was trying to test the Gripper Joystick Controller found at the Intera Examples. I have a PS3 controller and have successfully paired it to my ROS using the ps3/Joy tutorial. But when I follow the Intera tutorial on how to run the program, I am always facing the error "IndexError: tuple index out of range". I know it is not the same nut I tried the Gripper Keyboard example and that one worked perfectly on my Sawyer. If someone has experience running this example I would greatly appreciate the advice. I might also text it using an Xbox 360 controller but I think it should be working as it is because the connection is stable with the PS3 one. Thanks in advance for any advice. -Jorge
JUNCHAO posted a topic in RobotHello， I tried to run the gripper example with command "$ rosrun intera_examples gripper_keyboard.py", but it turned out with few errors. Few functions like "map_keyboard(args,limb)", "gripper=intera_interface.Gripper(limb)" have errors and the last two showed that the gripper is not attached. See screen shot attached. We bought Pneumatic Large Gripper Kit and assembled by exactly following the instruction and I am sure it was attached properly, but I don't know why it shows the gripper is not attached. Similarly, when I tried to run the second example with command "$ rosrun intera_examples joint_position_keyboard.py", it shows "Could not initialize the gripper". I wonder do I need to type any command to let the robot know the gripper is attached? Junchao Li
Hi, I attached a Weiss WSG50 gripper to our Sawyer and I would like to update the gravity compensation to account for the gripper's mass. I have the gripper's urdf here: https://github.com/nalt/wsg50-ros-pkg/blob/master/wsg_50_simulation/urdf/wsg_50.urdf How do I integrate this into Sawyer's URDF and make the controller use this at runtime? Thanks!
