HOKUYO LINUX DRIVER

The table below shows some of the basic features and prices of the Hokuyo units tested and compared in this article. The results from this test are shown below. The results of this testing are shown below. Hokuyo laser scan range. The behavior mimics what would happen if a small opaque object were placed close to the laser. This set of wires can also carry additional information such as synchronous output.

A more useful application would be to use multiple lasers or a laser on a moving platform to create a point cloud to analyze a 3D space. The Ethernet Base-TX communication uses a standard Ethernet plug and port to transfer the range data to and from the laser. This allows the user to quickly and easily connect the linuc and at once begin taking range data. Please sign in help.

In addition to the Hokuyo, we need a computer to read data. There is possibility of error make[1]: Please start posting anonymously - your entry will be published after you log in or create a new account. The featured Hokuyo lasers all worked well when operating within their given specifications. An image of the location of the tests is shown.

Finally, we will install rosinstall which helps by installing multiple source trees with a single command.

Using ROS to read data from a Hokuyo scanning laser rangefinder

The results from this test are shown below. After that, press F5 to build. The outdoor environment really highlighted the different abilities of each laser.

The dynamic test was similar to the other experiments with the acrylic sheets, except it was moved across the entire field of view of the laser. This problem becomes even more complicated when the laser is not connected through a local network. Scanner synchronous and Failure output.

HelloI installed the ROS software on my Ubuntu system properly and ran most of the tutorials to check if I have installed correctly and it did. The acrylic sheet acts in a similar way as it did during the indoor tests. The sensor sends out light at a known wavelength and then reads the reflected light after it has traveled out to the environment and back to the sensor. Software Engineering Best Practices. The major variation in each product is the maximum distance in the scanning range.

Hokuyoo advantage of this testing environment was the presence of both translucent surfaces glass and opaque surfaces hookuyo, plastic and other office liinux items. To download the hokuyo node, enter. Connecting to a hokuyo laser separate from the robot.

URG C Library document

The first step is to install and configure ROS. It is important to point out that the laser ljnux capture data through the acrylic but it must be at an angle.

You should see the messages: The final step in this tutorial is to visualize this data using rviz. Also, it can be seen that there is a vehicle far in the distance at the center of the image.

About following environment, ilnux library installation method is explained. USTLX indoor results with acrylic.

Powered by Askbot version 0. The setup of the indoor test with the protective acrylic can be seen in the following image. Top view of Hokuyo lasers. Once a method to provide electrical power is found, there is still further work that must be done to connect the sensors. To download the hokuyo node, enter Sudo apt-get install ros-indigo-hokuyo-node Plug in your hokuyo to the usb drive.

ROS is a robust robot operating system with easily integrated nodes for controlling a variety of sensors and motors.
