2015-10-08 00:57:36 -0500 | asked a question | Using phidget or phidget driver pkg to see the feedback of encoder Does anyone use phidget pkg of phidgets driver pkg to see the feedback of encoder in ros? Now I have the phidgets encoder hardware ( http://www.phidgets.com/products.php?... ) and a DC motor with encoder. I want to see the feedback of ros side when running some phidgets node ? which one do I need to choose? 1: http://wiki.ros.org/phidgets 2:http://wiki.ros.org/phidgets_drivers Hope can get some hints from you guys. Thanks!! |

2015-07-15 10:24:57 -0500 | asked a question | Fail to run the kangaroo_driver node Hi.Today in lab I want to use the ROS in virtual box to control the motor connect to the kangaroo and sabertooth set. The node is compiled successfully and I did find out the port which has been using and make it available. Besides, I have modified the port setting inside the kangaroo_driver.cpp. Everything seems perfect. When I tried to run the node, it shows "fail to read from the serial. Sent start signals to clear." The address of the code used is https://github.com/smd-ros-devel/kang... |

My question is What a_scale and l_scale stand for? And in Switch(c). Why value of angular and linear are all 1.0 rather than 2.0. Thank you very much! |
2015-05-26 10:26:00 -0500 | asked a question | Use ros sabertooth-kangaroo set to control a motor. Hi. I just recently start doing a project which require us to use ros to control a motor. For example, when press the W and S button in the keyboard then the motor will run forward or backward respectively. So may I ask what should be used to achieve this? Thankx!!! |
