2017-04-19 16:11:34 -0500 marked best answer Jetson TK1 can not find USB port ( Kinect/RPLidar)

I have installed ROS on Jetson TK1. When I connected sensors (like Kinect, RPlidar ) to the USB port and list the device, the device did not appear as expected ($ ls /dev/ttyUSB* ). How to deal with this?

Cheers, Rickardo

Hi, does anyone try ros navigation stack and SLAM package on Nvidia TK1 or INFORCE 6540. How is the performance?

2016-11-06 07:49:09 -0500 asked a question How to user the serial read byte -example

Can anyone give me an example to use the serial pkg to read byte from serial port to a buffer.

https://github.com/wjwwood/serial

size_t read (uint8_t *buffer, size_t size) size_t read (std::vector< uint8_t > &buffer, size_t size=1)

I tried the method but failed with the following exception.

terminate called after throwing an instance of 'serial::SerialException' what(): SerialException device reports readiness to read but returned no data (device disconnected?) failed. Aborted (core dumped)

size_t size= 1;
uint8_t * buffer = new uint8_t;
size_t read_byte;
if(ser.available())
{
     read_byte =  ser.read(buffer, size);
}

2016-11-06 07:39:26 -0500 asked a question How to generate binary .deb file of a ROS package locally without ROS buldfarm

Hi there,

During our work, we need some binary .deb package of some ROS packages. I only need a local manner to generate a ".deb" file to obfuscate my source code and thereby, the other can use the package without seeing the source code.

I have been digging around the ROS release process and ros buldfarm. But things are not really clear to us yet. Would you please suggestion me how to do, or how would you advise us to do in order to generate such installers package?

Your suggestion and help to solve this is pretty appreciated.

Best,

Rickardo

Many thanks, gvdhoorn . I have tried cheinstall, but failed. Could you please show me the detail for this process. Cheers. What I need is to create a binary deb of my own package and share it to the others without the source code for some reason.

Dear Mates,

Can anyone tell me how to limit navigation planner plan in specific area on the map, i.e just from the middle of corridors/edges? So that the robot can only move following the centre of walls.

Hi ,

How to limit robot move in specific area on the map, i.e create a virtual corridor ? Currently, I have a map of robot`s environment, the robot should be forbidden near the walls or obstacles during planning. So that the robot can only move inside the virtual corridor.
