LEGO-Based Robot Arm With Motion Planning

Robotic arms have found all manner of applications in industry. Whether its welding cars, painting cars, or installing dashboards in cars, robotic arms can definitely do the job. However, you don’t need to be a major automaker to experiment with the technology. You can build your own, complete with proper …read more

Nvidia Jetson Robots Get A Head Start With Isaac Software Tools

We live in an exciting time of machine intelligence. Over the past few months, several products have been launched offering neural network processors at a price within hobbyist reach. But as exciting as the hardware might be, they still need software to be useful. Nvidia was not content to rest …read more

Little Lamp To Learn Longer Leaps

Reinforcement learning is a subset of machine learning where the machine is scored on their performance (“evaluation function”). Over the course of a training session, behavior that improved final score is positively reinforced gradually building towards an optimal solution. [Dheera Venkatraman] thought it would be fun to use reinforcement learning …read more

Buy Or Build An Autonomous Race Car To Take The Checkered Flag

Putting autonomous vehicles on public roads takes major resources beyond most of our means. But we can explore all the same general concepts at a smaller scale by modifying remote-control toy cars, limited only by our individual budgets and skill levels. For those of us whose interest and expertise lie in software, Amazon Web Services just launched AWS DeepRacer: a complete package for exploring machine learning on autonomous vehicles.

At a hardware level, the spec sheet makes it sound like they’ve bolted their AWS DeepLens machine vision computer on an 1/18th scale monster truck chassis. But the hardware is only …read more

Is 2018 Finally the Year of Windows on the Robot?

Microsoft is bringing ROS to Window 10. ROS stands for Robot Operating System, a software framework and large collection of libraries for developing robots which we recently wrote an introductory article about, It’s long been primarily supported under Linux and Mac OS X, and even then, best under Ubuntu. My own efforts to get it working under the Raspbian distribution on the Raspberry Pi led me to instead download a Pi Ubuntu image. So having it running with the support of Microsoft on Windows will add some welcome variety.

To announce it to the world, they had a small booth …read more

Modular Robotics Made Easier With ROS

A robot is made up of many hardware components each of which requires its own software. Even a small robot arm with a handful of servo motors uses a servo motor library.

Add that arm to a wheeled vehicle and you have more motors. Then attach some ultrasonic sensors for collision avoidance or a camera for vision. By that point, you’ve probably split the software into multiple processes: one for the arm, another for the mobility, one for vision, and one to act as the brains interfacing somehow with all the rest. The vision may be doing object recognition, something …read more
