Robot Rovers of the Early Space Race

Posted on by

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

Watney: A Fully 3D Printed Rover Platform

Posted on by

We’re getting to the point that seeing 3D printed parts in a project or hack isn’t as exciting as it was just a few years ago. The proliferation of low-cost desktop 3D printers means that finding a printer to squirt out a few parts for your build isn’t the adventure it once was. Gone are the days of heading to a local hackerspace or college hoping their janky Mendel felt like working that day. But all that really means is that hackers and makers now have the ability to utilize 3D printing even more. Forget printing one or two …read more

3D Printed Arduino Bot is Limbo Master

Posted on by

As if we didn’t have enough to worry about in regards to the coming robot uprising, [Ali Aslam] of Potent Printables has recently wrapped up work on a 3D printed robot that can flatten itself down to the point it can fit under doors and other tight spaces. Based on research done at UC Berkeley, this robot is built entirely from printed parts and off the shelf hardware, so anyone can have their own little slice of Skynet.

The key to the design are the folding “wings” which allow the robot to raise and lower itself on command. This not …read more

An Arduino Powered Tank Built To Pull Planes

Posted on by

Surely our readers are well aware of all the downsides of owning an airplane. Certainly the cost of fuel is a big one. Birds are a problem, probably. That bill from the traveling propeller sharpener is a killer too…right? Alright fine, we admit it, nobody here at Hackaday owns an airplane. But probably neither do most of you; so don’t look so smug, pal.

But if you did own a plane, or at least work at a small airport, you’d know that moving the things around on the ground is kind of a hassle. Smaller planes can be pulled by …read more

Control a Swarm of RC Vehicles with ESP8266

Posted on by

Over at RCgroups, user [Cesco] has shared a very interesting project which uses the ever-popular ESP8266 as both a transmitter and receiver for RC vehicles. Interestingly, this code makes use of the ESP-Now protocol, which allows devices to create a mesh network without the overhead of full-blown WiFi. According to the Espressif documentation, this mode is akin to the low-power 2.4GHz communication used in wireless mice and keyboards, and is designed specifically for persistent, peer-to-peer connectivity.

Switching an ESP8266 between being a transmitter or receiver is as easy as commenting out a line in the source code and reflashing the …read more

Remember When Scratch-Built Robots Were Hard?

Posted on by

Even simple robots used to require quite a bit of effort to pull together. This example shows how far we’ve come with the tools and techniques that make things move and interact. It’s a 3D printed rover controlled by the touchscreen on your phone. This achieves the most basic building block of wheeled robotics, and the process is easy on you and your pocketbook.

We just can’t stop loving the projects [Greg Zumwalt], aka[gzumwalt], is turning out. We just saw his air-powered airplane engine and now this little rover perks our ears up. The design uses the familiar trick of …read more

The Last Interesting Rover Had A Gas Turbine Engine

Posted on by

If you have a car parked outside as you are reading this, the overwhelming probability is that it has a reciprocating piston engine powered by either petrol(gasoline), or diesel fuel. A few of the more forward-looking among you may own a hybrid or even an electric car, and fewer still may have a piston engine car powered by LPG or methane, but that is likely to be the sum of the Hackaday reader motoring experience.

We have become used to understanding that perhaps the era of the petroleum-fueled piston engine will draw to a close and that in future decades …read more

Gorgeous Engineering Inside Wheels of a Robotic Trail Buddy

Posted on by

Robots are great in general, and [taylor] is currently working on something a bit unusual: a 3D printed explorer robot to autonomously follow outdoor trails, named Rover. Rover is still under development, and [taylor] recently completed the drive system and body designs, all shared via OnShape.

Rover has 3D printed 4.3:1 reduction planetary gearboxes embedded into each wheel, with off the shelf bearings and brushless motors. A Raspberry Pi sits in the driver’s seat, and the goal is to use a version of NVIDA’s TrailNet framework for GPS-free navigation of paths. As a result, [taylor] hopes to end up with …read more

Earth Rovers Explore Our Own Planet

Posted on by

While Mars is currently under close scrutiny by NASA and other space agencies, there is still a lot of exploring to do here on Earth. But if you would like to explore a corner of our own planet in the same way NASA that explores Mars, it’s possible to send your own rover to a place and have it send back pictures and data for you, rather than go there yourself. This is what [Norbert Heinz]’s Earth Explorer robots do, and anyone can drive any of the robots to explore whatever locations they happen to be in.

A major goal …read more

Hackaday Prize Entry: SafeRanger, a Roving Power Plant Monitor

Posted on by

Engineering student [Varun Suresh] designed his SafeRanger rover to inspect oil and gas power plants for abnormal temperatures as well as gas leaks. The rover explores critical areas of the factory, and data is sent to a control center for analysis.

[Varun] built his robot around a Devastator chassis kit from DFRobot, and equipped it with a FLIR Lepton thermal camera and an MQ2 gas sensor, both monitored by a Raspberry Pi. The twin brushless DC motors are controlled by an L293D motor driver IC in conjunction with an Arduino Nano; steering is accomplished with an HC-05 Bluetooth module and …read more
