2016-01-26 05:55:50 -0500 | answered a question | robot rotation in place speed lower then minimum i was able to find in the base_local_planner package in the trajectory planner cpp file a minimum value that was set too low 0.4 and i changed it to 0.6 and than things worked out :) |
2016-01-24 08:35:51 -0500 | asked a question | robot rotation in place speed lower then minimum hello everyone i am having a difficulty with my robot. it navigates to a goal pretty well. the thing is when it needs to rotate at the end to the orientation of the goal it doesnt seem to move. when i look at the cmd_vel the robot receives a value of 0.457.. but the minimum value required for my robot to rotate is 0.55 this is also the value set in the base_local_planner_params so i dont get how can a value lower than the minimum is sent to the robot please help me figure this one out here is my base_local_planner_params file: |

2015-12-07 07:03:33 -0500 | answered a question | ros_arduino_bridge cant get my robot to move thank you very much for your reply! :) i was able to fix this issue by changing the "gear reduction" in my configuration file, by putting "#" before it. about the encoder, i will soon recieve my encoder that i ordered online. it is 20 ticks per one revoulution, so thats why i wrote this value. and it is mounted straight on the wheel thanks again! :) |

2015-12-06 07:00:37 -0500 | asked a question | ros_arduino_bridge cant get my robot to move hello everyone, basically i want to send twist command to my robot and get it moving but nothing happans when i send the twist commands... i have successfully uploaded the ros_arduino_bridge sketch in to my robot, i can get it moving by sending "m 20 20" (through serial monitor) and get encoder data "0 0" (although i still don't have encoders plugged in) . in my config file .yaml i have changed to the following settings: i am successfully launching the ros communication with the arduino, even pin 13 with the LED is flashing (more) |
