Looking at Things From a Different Angle

This robot inspects objects from different angles to classify them with a high degree of accuracy in real world scenarios.

Object recognition is a critical piece of many machine learning applications. Whether the goal is to create an autonomous car, a warehouse robot, or a package delivery drone, in each case, the devices must be capable of recognizing the objects that are around them. There are many proven models that classify a wide range of objects with a high degree of accuracy; however, these models do not always perform as expected under real world scenarios.

Robot Dog V3 – 3D Printed & Open Source #1

I’ve previously built several robot dogs which used a variety of servos and brushless motors. The most agile robot dogs are the ones with back-drivable low-ratio reducers which allows the motor to be back-driven so we get some natural spring in the legs – which can be controlled on the fly with software. So it’s time for openDog V3 – this version uses my Cycloidal Drives which I’ve developed over the last few months. I will eventually publish the CAD and code as open source when it works.

An Arduino-powered underwater ROV made out of PVC pipe

Exploring the vast underwater world is exciting, and personal breathing devices such as SCUBA allow for people to descend far further than usual. However, robots can be even better since they can operate much longer and more efficiently than a person. And because these underwater remotely operated vehicles (ROVs) can be so expensive, Ranuga Amargasinghe wanted to construct his own DIY version that costs less.

UC Riverside Roboticists Create Airhead, a Piano-Playing Robot Driven by “Air-Powered” Memory Chips

Inspired by player pianos and thermostats from the early 1900s, Airhead ditches electronics in favor of pneumatic RAM modules.

University of California at Riverside (UC Riverside) engineers have created what they describe as “air-powered computer memory,” which drives a robot — dubbed, amusingly, “Airhead” — to play the piano.

“Pneumatically-actuated soft robots have advantages over traditional rigid robots in many applications,” the researchers write in the abstract to their paper. “In particular, their flexible bodies and gentle air-powered movements make them more suitable for use around humans and other objects that could be injured or damaged by traditional robots.”

Spot Release 3.0 Gives Everybody’s Favorite Quadrupedal Robot Edge AI Powers, Improved Autonomy

Boston Dynamics has unveiled an upgrade for its quadrupedal Spot robot, Spot Release 3.0, which offers new autonomy functionality, AI-powered data collection, and the ability to operate the arm remotely — even opening doors.

“We’ve been working closely with Spot users in asset-intensive industries to operationalize the robot on their sites,” the Boston Dynamics team writes of the new upgrade. “With Spot Release 3.0, we’ve added flexible autonomy and repeatable data capture, making Spot the data collection solution you need to make inspection rounds safer and more efficient.”

How To Make Robots Move Smoothly | Arduino Tutorial

There are lots of great animatronic and robotics props and projects out there, and it’s easy to make r/c servos and other actuators move using the Arduino servo library. This means that the servos stops and start very suddenly, moving as fast as they can between positions. In this video I’m going to show you two lines of very simple code to make things smoother.

This Open Source Robotic Leg Performs Jumps and Walks All on Its Own

Although it might look a bit weird on its own, the Overleap robotic leg is capable of some incredible things.

Aaron de los Santos has created an extremely weird backyard decoration: a single robotic leg that hops around in a circle. But do not let this simple premise fool you, as the device called Overleap has some serious engineering put into it. The leg is able to make quick jumps in rapid succession while remaining very accurate. It can also make small adjustments whilst it hops that causes it to almost run in a circular pattern.

This Insect-Sized Robot Has the Same Agility as a Cheetah

UC Berkeley engineers developed a robot that can traverse complex terrain and quickly avoid obstacles.

Most insects and spiders climb walls and walk on ceilings through sticky footpads, allowing them to stick on surfaces. UC Berkeley engineers used the same electrostatic adhesive concept to develop an insect-sized robot with similar swerving and pivoting capabilities as a cheetah. As a result, the robot can travel through a maze while avoiding sudden obstacles.

RaspberryPi Zero Takes the Wheel in Miniature Fighting Robot

Looking to capitalize on his familiarity with the Raspberry Pi, [Sebastian Zen Tatum] decided to put the diminutive Pi Zero at the heart of his “antweight” fighting robot, $hmoney. While it sounds like there were a few bumps in the road early on, the tuxedoed bot took home awards from the recent Houston Mayhem 2021 competition, proving the year of Linux on the battle bot is truly upon us.

Compared to using traditional hobby-grade RC hardware, [Sebastian] says using the Pi represented a considerable cost savings. With Python and evdev, he was able to take input from a commercial Bluetooth game controller and translate it into commands for the GPIO-connected motor controllers. For younger competitors especially, this more familiar interface can be seen as an advantage over the classic RC transmitter.
