Rube Goldberg machines are all about taking as many steps as possible to do something really simple. In this clip from the Japanese educational television program, PythagoraSwitch, a small red ball called Biisuke travels through a Rube Goldberg machine to rescue his yellow and green-colored brothers from the ball prison. It’s a pretty neat idea to turn the classic RG machine into an epic quest.
You can find more small machines on the program’s YouTube page.
Youtuber, James Risner, has built this mesmerizing spiral train setup that looks pretty amazing to view in endless GIF format. I’d like to see a similar video with different colored trains that could synch up in different ways through the train’s passage.
This impressive robot is named “Hadrian” after the ancient Roman emperor who built a wall in Northern Britain. Mark Pivac is the Australian aeronautical and mechanical engineer who has been designing the machine, which is expected to hit the market sometime around 2017. Reportedly, the robot can lay up to 1,000 bricks per hour and build the brick frame of a standard house in one to two days, 20 times faster than a human brick layer.
Well, enough with the build-up, here’s the machine in simulated action:
I guess if you are thinking about going into bricklaying for a career, you’re out of luck. Otherwise, it seems like great news all around.
Check out this 360° video made as a demo by Samsung. If your internet speed can handle it, I recommend watching it in the full 4K resolution. It will be pretty amazing to hook up the Oculus Rift to video like this and get the fully immersive experience.
Use the ‘W, A, S, D’ keys to control direction on a computer.
Use the + and – keys to zoom.
I think you have to move your phone around if you are watching on mobile. But again, the real experience is to watch this type of video with an immersive virtual reality headset. FYI: you can cheaply get this experience with something like Google Cardboard and your mobile phone.
The BMW S54 was a high performance engine with these features:
1. Increased cylinder bore to 87 mm (from 86.4 mm) for a new total displacement of 3,246 cc (from 3,201 cc)
2. Modified camshafts
3. High pressure Double VANOS continuously variable valve timing system with faster operation at high rpm
4. Increased compression to 11.5:1 (from 11.3:1)
5. More advanced BMW/Siemens MSS 54 engine management control
6. Finger-type rocker arms for reduced reciprocating mass and friction
7. One-piece aluminum head casting for lighter weight
8. Scavenging oil pump to maintain pressure during heavy cornering
An unknown source broke the entire engine down and laid it out carefully for us to enjoy. Now we just need someone to label each part for our didactic purposes.
In a new report from Nature, research from evolutionary roboticist, Josh Bongard, at the University of Vermont in Burlington demonstrates a self-correcting hexapod.
From the article:
“After a fault, such as the loss of one of its feet or a stuck knee, the robot uses its on-board camera to detect that something is slowing it down or preventing it from walking straight. Rather than attempting to diagnose the problem, the robot simply tries out new patterns of motion until it finds one that enables it to restore an acceptable level of performance.”
Robots working in disaster areas may become injured and having this ability to quickly self-correct walking patterns can be crucial for success of a mission. Of course, the robot is not really learning with evolutionary algorithms or through techniques like deep learning. Instead, the robot is pre-programmed to with around 13,000 walking patterns that the robot can quickly cycle through in the event of injury.
The programming also helps the robot with unusual terrains in which a new walking pattern may be more efficient. This will help walking robots become more autonomous in natural terrains.
