Krave Antweight Robot Gets Eaten And Stays Alive

The battle’s are done and the results are in — [AltaPowderDog]’s, aka [Carter Hurd],  cardboard and foam armor, lightweight Krave robot beat its metal cousins in 2016 and fared well in 2017. How did a cardboard Krave cereal box and foam board robot do that you ask? The cardboard and foam outer structure was sliced, smashed and generally eaten while the delicate electronics, motors and wheels remained buried safely inside.

We covered the making of his 2016 version but didn’t follow-up with how it fared in that year’s Illinois Bot Brawl competition. As you can see in the exciting first …read more

Simple Step-Climbing Robot Climbs Like It’s On Mars

[Navin Khambhala] is a master at making simple what most would expect to be a complex build. Now he’s done it again with a remote controlled robot that can easily climb steps and role over rough terrain. The parts count is small and many of them are commonly available.

The suspension that makes it all possible is the rocker-bogie. It’s the same suspension we’ve all seen used by the various rovers ambling around on Mars. The whole frame is made of PVC pipes with some connecting metal bars, and each wheel has its own twelve-volt DC motor. Motor control is …read more

Hackaday Prize Best Product Finalist: Reconfigurable Robots

Reconfigurable robots have been around for ages. One of the first and most popular reconfigurable robots came out of the MIT Media Lab, and last year, DTTO, a modular snake-like robot, won the 2016 Hackaday Prize. There’s a lot that can be learned from a robot that can turn from a walker to a swimmer to something that clambers over rough terrain, and [Salvador]’s EMME does just that. It’s a 3D printed robot and controller that’s the closest you can get to, ‘the Lego of robots’. All you need to do is plug some wheels into a controller and you’re …read more

Wooden Domino Laying Machine

[Matthias Wandel]  has come up with another awesome machine, this time a machine that sets up neat rows of dominos. If you’ve followed [Matthias]’s work over the years then you’ll know that this is a wooden version of one he made out of LEGO® back in 2009.

In true [Matthias] fashion he uses just the one motor both for moving the machine along and for pushing the dominos in place. Not satisfied with that efficient use of parts, the rubber band belts that transfer rotation from the motor shaft to the wheels (bearings) double as the rubber surfaces for those …read more

Hackaday Prize Entry: A Six Axis Robotic Arm With Fingertip Control

If you were a child of the 1980s whose fascination extended to the contents of your local Radio Shack store, you may remember the Armatron robot arm as a particular object of desire. It was a table top robot arm operated not by motors or a microcontroller, but by a clever set of gears directed manually from a pair of joysticks. If you took a look at it with an eye to control from your 8-bit home computer you were likely to be disappointed, but nevertheless it was an excellent toy.

The Armatron may be long gone, but if you …read more

Wire-bots, Roll Out!

Designing and 3D-printing parts for a robot with a specific purpose is generally more efficient than producing one with a general functionality — and even then it can still take some time. What if you cut out two of those cumbersome dimensions and still produce a limited-yet-functional robot?

[Sebastian Risi] and his research team at the IT University of Copenhagen’s Robotics, Evolution, and Art Lab, have invented a means to produce wire-based robots. The process is not far removed from how industrial wire-bending machines churn out product, and the specialized nozzle is also able to affix the motors to the …read more

Robot: Do My Bidding!

Remote control robots are nothing new. Using Bluetooth isn’t all that unusual, either. What [SayantanM4] did was make a Bluetooth robot that accepts voice commands via his phone. The robot itself isn’t very remarkable. An Arduino and an HC05 module make up most of the electronics. A standard motor driver runs the two wheels.

The Arduino doesn’t usually do much voice processing, and the trick is–of course–in the phone application. BT Voice Control for Arduino is a free download that simply sends strings to a host computer via Bluetooth. If you say “Hello” into your phone, the robot receives *Hello# …read more

Pixar Style Robots Are Treasure Trove Of Building Tricks

[Alonso Martinez] is an artist working on virtual characters at Pixar so it’s no wonder that his real life robots, Mira and Gertie,  have personalities that make them seem like they jumped straight out of a Pixar movie. But what we really like are the tricks he’s used inside to bring them to life that are sure to get reused for the same or other things.

For example, Mira’s head can rotate in yaw, pitch and roll. To figure out how to make it do that he recalled having a joystick called the Microsoft Sidewinder Pro that had force feedback. …read more

3D-Printed Rover Rolls Light and Looks Right

[Rick Winscott]’s RO-V Remotely Operated Vehicle instructable shows you how to make this cool-looking and capable robot. The rover, a 1/10th scale truggy, sports a chassis printed in silver and black PLA. It’s got a wireless router mounted on the back, and a webcam in a 2-servo gimbal up front. [Rick] made his own steering rack and pinion out of 3D printed parts and brass M3-threaded rods which he tapped himself.

The simplified drive system nixes the front, rear, and center differentials, thereby saving [Rick] on printing time, complexity, and weight — he was able to include a second 4000 …read more

Robot Draws Using Robust CNC

While initially developed for use in large factory processes, computer numeric control (CNC) machines have slowly made their way out of the factory and into the hands of virtually anyone who wants one. The versatility that these machines have in automating and manipulating a wide range of tools while at the same time maintaining a high degree of accuracy and repeatability is invaluable in any setting. As an illustration of how accessible CNC has become, [Arnab]’s drawing robot uses widely available tools and a CNC implementation virtually anyone could build on their own.

Based on an Arudino UNO and a …read more
