Robot Blade Runner Turns In World Record Time

While we wish colleges and universities competed more on academics, we can’t deny that more people are interested in their athletics programs. Oregon State, however, has done a little of both since their bipedal robot, Cassie, became the world’s fastest bipedal robot according to the Guinness Book of World Records. You can see a video of the 100 meter run below, but don’t blink. The robot turned in a time of around 25 seconds.

Impressive, but still not on par with Usan Bolt’s time of under 10 seconds for the same distance. If you want to see what that would be like, try running the long way across a football field and see how far you get in 25 seconds. There isn’t a lot of technical detail about the robot, but you can intuit some things from watching it go. You can also find a little more information on the robot and some of its siblings on the University’s website.

If you think robots won’t ever run as well as humans, we used to think the same thing about playing chess. This doesn’t look like we normally envision a bipedal robot. Then again, there isn’t any reason robots have to look, or move, like we do.

Doomba: Purifying Your Floors With Fire

If you’ve ever thought that your floor cleaning robot eating the fringe on your rug wasn’t destructive enough, [Kyle Brinkerhoff] is working on a solution — Doomba.

This blazingly fast RC vehicle has a tank of butane/propane gas nestled snugly amid its electronics and drive system to fuel a (not yet implemented) flamethrower. Watching how quickly this little bot can move in the video below certainly made our hearts race with anticipation for the inevitable fireworks glory of completed build. Dual motors and a tank-style drive ensure that this firebug will be able to maneuver around any obstacle.

As of writing, the flamethrower and an updated carriage for the drivetrain are underway. Apparently, spinning very quickly in circles can be just as disorienting for robots as it is for us biological beings. During the test shown below, the robot kicked out one of its drive motors. [Kyle] says the final touch will be putting the whole assembly inside an actual Roomba shell for that authentic look.

With spooky season upon us, it’s always good to have the cleansing power of fire at hand in case you find more than you bargained for with your Ghost-Hunting PKE Meter. While there’s no indication whether Doomba can actually run DOOM, you might be interested in this other Doomba Project that uses Roomba’s maps of your house to generate levels for the iconic shooter.

Self-Driving Laboratories Do Research On Autopilot

Scientific research is a messy business. The road to learning new things and making discoveries is paved with hard labor, tough thinking, and plenty of dead ends. It’s a time-consuming, expensive endeavor, and for every success, there are thousands upon thousands of failures.

It’s a process so inefficient, you would think someone would have automated it already. The concept of the self-driving laboratory aims to do exactly that, and could revolutionize materials research in particular.

Robotic Platform Is Open Sourced And User Friendly

Having a 3D printer or a CNC machine available for projects is almost like magic. Designing parts in software and having them appear on the workbench is definitely a luxury. But for a lot of us, these tools aren’t easily available and projects that use them can be out-of-reach. That’s why one of the major design goals of this robotics platform was to use as many off-the-shelf components as possible.

The robot is called the OpenScout and, as its name implies, intends to be a fully open-source robotics platform for a wide range of use cases. It uses readily-available aluminum extrusion as a frame, which bolts together without any other specialized tools like welders. The body of the robot is articulating, helping it navigate uneven terrain outdoors. The specifications also call for using an Arduino to drive the robot, although there is plenty of space in the robot body to house any robotics platform you happen to have on hand.

For anyone looking to get right into the useful work of what robots can do, rather than spending time building up a platform from scratch, this is an excellent project. It’s straightforward and easy to build without many specialized tools. The unique articulating body design should make it effective in plenty of environments. If you do have a 3D printer, though, that opens up a lot of options for robotics platforms.

Robots Chase Down Balls In Fun Outdoor Game

Art installations aren’t always about static sculpture or pure aesthetics. In the case of Operation Kiba, they can be fun games for everyone to enjoy.

The aim of Operation Kiba is for the players to collect all the “balls” on the playing field, which are intended to represent scoops of ice cream. Collecting the balls is done via robot. Each player is ostensibly tasked with collecting one color of ball or the other, but players often decide to work together in harmony instead. The balls are released at the start of the game by tipping over a big bowl. This is half the fun, and is achieved by tugging a string which upends the vessel and scatters the balls.

The remote-control robots themselves come from an earlier art installation the group built called Bubble Blast. They’re built using a 3D printed chassis, with wheels on each side driven by DC gear motors. With tank-style steering, they can rotate on the spot, providing good maneuverability. An Arduino Nano runs the show, receiving commands over a 433 MHz radio link. Power is via DeWalt cordless drill batteries, and the robots are controlled via arcade sticks. They’re color-coded to match the balls in the game.

As far as art installations go, it may not be fancy or pretentious, but it certainly looks like a lot of fun. We’re sure it could eventually guide many players towards the exciting world of antweight combat robotics. Video after the break.

Hackaday Links: September 18, 2022

We always love when people take the trouble to show information in new, creative ways — after all, there’s a reason that r/dataisbeautiful exists. But we were particularly taken by this version of the periodic table of the elements, distorted to represent the relative abundance on Earth of the 90 elements that make up almost everything. The table is also color-coded to indicate basically how fast we’re using each element relative to its abundance. The chart also indicates which elements are “conflict resources,” basically stuff people fight over, and which elements go into making smartphones. That last bit we thought was incomplete; we’d have sworn at least some boron would be somewhere in a phone. Still, it’s an interesting way to look at the elements, and reminds us of another way to enumerate the elements.

It’s wildfire season in the western part of North America again, and while this year hasn’t been anywhere near as bad as last year — so far — there’s still a lot of activity in our neck of the woods. And wouldn’t you know it, some people seem to feel like a wildfire is a perfect time to put up a drone. It hardly seems necessary to say that this is A Really Bad Idea™, but for some reason, people still keep doing it. Don’t misunderstand — we absolutely get how cool it is to see firefighting aircraft do their thing. The skill these pilots show as they maneuver their planes, which are sometimes as large as passenger jets, within a hundred meters of the treetops is breathtaking. But operating a drone in the same airspace is just stupid. Not only is it likely to get you in trouble with the law, but there’s a fair chance that the people whose property and lives are being saved by these heroic pilots won’t look kindly on your antics.

Robot: Will Draw For Food

Biological systems often figure out the best ways to get what they need to survive. Now a robot created by researchers at Worcester Polytechnic Institute, Imperial College London, and the University of Illinois Urbana Champaign can make the same claim. The robot operates in front of a plate that has electrical terminals on one end and various obstacles between those terminals and the robot.

The robot can pick up and rearrange some of the items on the plate and then draws paths to the terminals using conductive ink. The effect is the robot gets to “eat” if it solves the connection puzzle.
