News about the electronics of MyzharBot
Two days ago at Computex Nvidia annunced the new Jetson Xavier, a new embedded board with the robotics as target. It’s been a little more than one year since Nvidia released the amazing Jetson TX2. We were talking about the incredible calculation power available for the first time on an…
This news is not directly related to MyzharBot project, but somehow it will give to MyzharBot a big improvement. Let’s start from the beginning…
The Computer Vision is a really computational power requesting task, if you work with computer vision you know that to reach very high frame rates you need to maximize the parallelism of the algorithms and you know that massive parallelism is reachable only moving elaborations to GPUs. The embedded massive…
The 7th march Nvidia launched the new Jetson TX2. In the launch post I described the differences with the previous Jetson and how the new Jetson TX2 can double the performances of the TX1. Now it’s time to see how it really works, so let’s stop the written words and let’s…
Well, it’s been a while since I published the latest news about MyzharBot project, what’s better than starting again from a really big news? Nvidia has presented the new Jetson module, Nvidia Jetson TX2 and it’s ready to get on board of MyzharBot
The power connector of the carrier board of the Nvidia Jetson TX1 is really solid and well done, but the strong vibration of a tracked robot can compromise its stability, so I decided to modify it to be sure that MyzharBot-v4 has a really robust power connection.
The motors that move MyzharBot are really powerful, really too much powerful for the motor drivers mounted on the little uBridge shield used originally by the amazing uNav Motor Control board made by Officine Robotiche. For this reason Mauro Soligo (under a “very little” pressure) realized the new uNavSB carrier board that uses the…
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…
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…
A new ROS package is available to verify the status of the DCDC-USB power converter by Mini-box.com and integrate the information with the ROS diagnostic system.
