Nvidia Jetson TX1 as Access Point and a guide to configure ROS-OpenCV for Jetsons

Nvidia_JetsonTX1_module

Making the final preparations for the participation of MyzharBot-v4 at the next conference GTC 2016 by Nvidia (San Jose, California, APRIL 4-7, 2016), I realized that it would be very helpful to have two guides for the realization of two basic operations for using the Nvidia Jetson TX1 on a …

Test of the integration of Ultrasonic Bumper with ROS framework

Ultrasonic Bumper Board - ROS test

In the following video you can see one of the first test of the integration of the Ultrasonic Bumper with the ROS framework. The test verifies the response time of two sensors mounted on the front panel of MyzharBot-v4. The ros_ultrasonic_bumper node acquires the ranges from the two sensors and publishes …

Ultrasonic Bumper Board based on ST Nucleo32

Sonar Board prototype

The optical spatial sensors mounted on MyzharBot v3 and MyzharBot v4 have a intrinsic limitation that make it unable to perceive obstacle that are too near along its forward motion direction. Asus Xtion Pro Live does not see obstacles nearest than 50cm, Stereolabs ZED does not see obstacles nearest than …

On MyzharBot v4 the Asus Xtion Pro Live RGB-D sensor has been replaced by the Stereolabs ZED stereo camera, in order to overcome the limitations of the Primesense technology in outdoor environment under the direct sunlight. The installation of the ZED camera on the Nvidia Jetson TK1 is really straigthforward as …

ROS: MyzharBot Virtual model and Asus Xtion Pro Live

MyzharBot model and RGB-D

I finally added Asus Xtion Pro Live to the virtual model of MyzharBot (not yet fully complete) in Rviz GUI. The result is the following To obtain this result you must run the following commands, every one in a different terminal: $ roslaunch ros_myzharbot_robot myzharbot.launch runs the “serial_bridge” node to …

New video: Teleoperation using ROS, Rviz and Interactive Marker Twist Server

Rviz & Interactive Marker Twist Server

In this new video a demonstration of the teleoperation of MyzharBot using the “Interactive Marner Twist Server“, an amazing Rviz tool that allows to send Twist (linear and angular speeds) messages to the “serial_bridge” node  simply dragging a circular marker. The final effect is really good and driving the robot is …
