Six Wheels (En)rolling: Mars Rovers Going To School

Few things build excitement like going to space. It captures the imagination of young and old alike. Teachers love to leverage the latest space news to raise interest in their students, and space agencies are happy to provide resources to help. The latest in a long line of educator resources released by NASA is an Open Source Rover designed at Jet Propulsion Laboratory.

JPL is the birthplace of Mars rovers Sojourner, Spirit, Opportunity, and Curiosity. They’ve been researching robotic explorers for decades, so it’s no surprise they have many rovers running around. The open source rover’s direct predecessor is ROV-E, …read more

Robot Rovers of the Early Space Race

In the early 1970s, the American space program was at a high point, having placed astronauts upon the surface of the moon while their Soviet competitors had not taken them beyond an Earth orbit. It is however a simplistic view to take this as meaning that NASA had the lead in all aspects of space exploration, because while Russians had not walked the surface of our satellite they had achieved a less glamorous feat of lunar exploration that the Americans had not. The first Lunokhod wheeled rover had reached the lunar surface and explored it under the control of earth-bound …read more

Roboshield Helps Your Robot Walk and Talk

The joy of building robots comes from being able to imbue them with as much or as little personality and functionality as you wish during the design and build process. While creative flair and originality is always a good thing, there’s a lot of basic needs many robots have in common with each other, so where possible it’s good to avoid reinventing the wheel so more time can be spent on more advanced features. Roboshield aims to help make the basics easy so you can let your robot freak flag fly!

At its core, it’s an Arduino shield that packs …read more

Handmade Robot Brings Stop Motion to Life

Stop motion animation is often called a lost art, as doing it (or at least, doing it well) is incredibly difficult and time consuming. Every detail on the screen, no matter how minute, has to be placed by human hands hundreds of times so that it looks smooth when played back at normal speed. The unique look of stop motion is desirable enough that it still does get produced, but it’s far less common than hand drawn or even computer animation.

If you ever wanted to know just how much work goes into producing even a few minutes of stop …read more

Controlling Robotics Visually

The world — and the Hackaday Prize — is filled with educational robots. These are small, wheeled robots loaded up with sensors, actuators, a few motor drivers, and some sort of system that is easy to program. The idea behind these educational robots is to give students an easy-to-use platform to test out code, learn inverse kinematics, and realize odometry is a lot harder than you think it is. Give these kids some time and patience, and you’ll have a fleet of Battlebots at the end of the semester, if the teacher is cool.

But there’s a problem with all …read more

ROPS Will Be The Board x86 Robot Builders Are Waiting For

If your robot has outgrown a Raspberry Pi and only the raw computing power of an x86 motherboard will suffice, you are likely to encounter a problem with its interfaces. The days of ISA cards are long gone, and a modern PC is not designed to easily talk to noisy robot hardware. Accessible ports such as USB can have interfaces connected to them, but suffer from significant latency in the process.

A solution comes from ROPS, or Robot on a PCI-e Stick, a card that puts an FPGA on a blazing-fast PCI-e card that provides useful real-world interfaces such …read more

FPV-Rover 2.0 Has 3D Printed Treads and Plenty of Zip

[Markus_p] has already finished one really successful 3D printed tracked robot build. Now he’s finished a second one using standard motors and incorporating what he learned from the first. The results are pretty impressive and you can see a video demo of the beast, below.

Most of the robot is PLA, although there are some parts that use PETG and flex plastic. There is an infrared-capable camera up front and another regular camera on the rear. All the electronics are pretty much off the shelf modules like an FPV transmitter and an electronic controller for the motors. There’s a servo …read more

A 3D-Printed Robot Actuator

Somehow, walking robots at our level never really seem to deliver on the promise that should be delivered by all those legs. Articulation using hobby servos is simple enough to achieve, but cumbersome, slow, and not very powerful. [Paul Gould] has a plan to make a better, 3D-printed articulated robot actuator.

His solution is both novel and elegant, a fairly conventional arm geometry that has at its joints a set of brushless motors similar to but a little larger than the kind you might be more familiar with on multirotors, paired with 3D-printed cycloidal gearboxes. Magnetic encoders provide the necessary …read more

Retrotechtacular: Voice Controlled Robot from 1961

We like to think that all these new voice-controlled gadgets like our cell phones, Google Home, Amazon Echo, and all that is the pinnacle of new technology. Enabled by the latest deep learning algorithms, voice-controlled hardware was the stuff of science fiction back in the 1961s, right? Not really. Turns out in around 1960, Ideal sold Robot Commando, a kid’s toy robot that featured voice control.

Well, sort of. If you look at the ad in the video below, you’ll see that a kid is causing the robot to move and fire missiles by issuing commands into a microphone. How …read more

Robot Dances to the Beat of New YouTube Subs

Sure, you could build some kind of numerical counter to keep track of new YouTube subscribers. But does an increasing digit display truly convey the importance of such an event? Of course not. What you need is something that recognizes this achievement for what it is and celebrates it with you. Something like Subby, the Interactive YouTube Subscriber Robot.

Whenever [brian brocken] gets a new subscriber, Subby’s little TV screen face lights up, and he either dances, salutes, or does another move within his impressive range of motion. [brian] wrote a Visual Basic app that searches his channel’s page for …read more
