2019-09-13 16:51:16 -0500 | marked best answer | What is rospy.sleep for? Really confused here. I want to delay certain publishing of messages to a topic for about 1-2 seconds. Can rospy.sleep help? My code already works fine, but I need the delay since I cannot put any delays in the Arduino/rosserial because it gives a lost sync error. Can someone please help? I've been doing this for 2 weeks and no solution so far. Here is my code. (more) |

2019-03-01 16:34:31 -0500 | marked best answer | raspicam_node and face_detector node together Hi! I seem to be confused about using face_detection in my custom bot. I have an RPi camera and want to use it to detect faces. I found one here. And I also found this neat face_detector package. Can someone please show me how this can be done? I'm running my ROS kinetic on raspbian and raspberry pi v3. I want my camera to detect faces and at the same time, display the results using Rviz in my ros-enabled remote computer. |
2019-03-01 16:30:54 -0500 | marked best answer | How to autonavigate in an unknown map I have a custom robot running on raspberry pi(raspbian) with ROS kinetic. I have understood from this that for the robot to avoid obstacles, there must be a known map that will only be generated by manually controlling the robot using either joystick or keyboard, etc. Can it be possible for the robot to autonomously navigate through an unknown map and avoid obstacles? Where can I find such package and how do I integrate this with my custom robot? My robot does not have any LIDARs, btw. It has an ultrasonic sensor in front, 2 analog IR sensors in the front sides and 2 digital IR sensors in the back. |
