Reanimating Boney the Robot Dog

[Divconstructors] cashed in after Halloween and picked up a skeleton dog prop from the Home Depot, for the simple and logical purpose of turning it into a robot.

The first step was to cut apart the various body parts, followed by adding bearings to the joints and bolting in a metal chassis fabricated from 1/8″ aluminum stock. This is all pretty standard stuff in the Dr. Frankenstein biz. For electronics he uses a Mega with a bark-emitting MP3 shield on top of it. Separately, a separate servo control board manages the dozenish servos — not to mention the tail-wagging stepper. …read more http://pje.fyi/Q2FwQl

An Interview with Alex Williams, Grand Prize Winner

Alex Williams pulled off an incredible engineering project. He developed an Autonomous Underwater Vehicle (AUV) which uses a buoyancy engine rather than propellers as its propulsion mechanism and made the entire project Open Source and Open Hardware.

The design aims to make extended duration missions a possibility by using very little power to move the vessel. What’s as remarkable as the project itself is that Alex made a goal for himself to document the project to the level that it is fully reproducible. His success in both of these areas is what makes the Open Source Underwater Glider the perfect …read more http://pje.fyi/Q20Nvd

Gorgeous Engineering Inside Wheels of a Robotic Trail Buddy

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 http://pje.fyi/Q1tQx4

Skynet will have Bobcats

There are so many autonomous devices nowadays that can run Skynet Inside™ that it’s hard to keep track. But one was still missing: the versatile Bobcat. When we say “Bobcat”, we mean track loader — it’s just one of those things that the name and the brand stoke together so strongly that it’s hard to actually recall the technical name. A company by the name of Built Robotics is betting on autonomous track loaders as being a big part of the future of construction.

The tractor can navigate, excavate, and carry a 1,000 pound load with 1 cm precision …read more http://pje.fyi/PxqBVf

LEGO Row Boat Is The Poolside Companion You Didn’t Know You Needed

Maybe it’s the upbeat music, or the views of a placid lake at sunset, or perhaps it’s just seeing those little plastic rods pumping away with all their might. Whatever the reason may be, the video [Vimal Patel] posted of his little remote controlled LEGO row boat cruising around on the open water is sure to put a smile on the face of even the most jaded hacker.

[Vimal] tells us that his creation is made up of over 140 unmodified LEGO parts, and is controlled over Bluetooth which connects to an app on his phone. While we would like …read more http://pje.fyi/PvqtFr

Soon You’ll Sit Inside a Robot’s Head at Work

MIT’s Computer Science and Artificial Intelligence Lab, CSAIL, has created a process of teleoperating a Baxter humanoid robot with an Oculus Rift VR headset. This project is partially aimed towards making manufacturing jobs a hell of a lot of fun telecommutable. It could even be a way to supervise robot workers from a distance.

In a nutshell, the user controls the robot remotely in a virtual reality environment. The user does this specifically in a VR environment modeled like a control room with multiple sensor displays, making it feel like they are sitting inside the robot’s head. By using hand …read more http://pje.fyi/PtddlJ

Researchers Squeeze Out a New Breed of Robot Locomotion

Researchers have been playing around with various oddball forms of robot locomotion; surely, we’ve seen it all, haven’t we? Not so! Lucky for us, [researchers at Stanford] are now showing us a new way for robots to literally extrude themselves from point A to point B.

This robot’s particular motion for mechanism involves unwinding itself inside out. From a stationary base, a reel caches meters of the robot’s uninflated polyethylene body, which it deploys by pressurizing. Researchers can make full 3D turns by varying the amount of inflated air in outer control chambers. What’s more, they can place end effectors …read more http://pje.fyi/PrbrQl
