Collaborate Disseminate
Walking robots that move smoothly are tricky to build and usually involve some sort of compliant leg mechanism — a robot limb that can rebound like natural physiology for much better movement than what a stiff machine can accomplish. In his everlasting quest to build a real working robot dog, …read more
For any sort of precision machine, precision adjustability is required. For the hacker this usually involves an adjustment screw, where the accuracy is determined by the thread pitch. This was not good enough for [Mark Rehorst] who wanted adjustment down to 10μm for his 3D printer’s optical end-stop, so …read more

Using a bit of tech to make up for a lack of skill is a time-honoured tradition, otherwise known as cheating among those who acquired the skill the hard way. Learning to wheelie a skateboard is usually paid for in bruises, but [blezalex] got around that by letting his electric …read more

While rockets launched from silos are generally weapons of war, [Joe Barnard] of [BPS.Space] thought model rocketry could still do with a little more thoomp. So he built a functional tube launched model rocket.
Like [Joe]’s other rockets, it features a servo-actuated thrust vectoring system instead of fins for stabilization. …read more
The solar panel technology we have available today doesn’t really lend itself to practical everyday transport. But when speed isn’t a concern, it can make for some very interesting autonomous rovers. One example of this is [Daniel Riley] aka [rctestflight]’s solar powered rover, which he built to live autonomously at …read more
For all the work done since the dawn of robotics, there is still no match for the human hand in terms of its dexterity and adaptability. Researchers of the IRIM Lab at Koreatech is a step closer with their ingenious BLT gripper, which can pinch with precision or grasp a …read more
Watching a child learn to run is a joyous, but sometimes painful experience. It seems the same is true is for [James Bruton]’s impressive Sonic the Self-Balancing robot, even with bendable knees and force sensitive legs.
We covered the mechanical side of the project recently, and now [James] has added …read more
Every well-equipped wood shop has a dust collection system, with blast gates at every tool to direct the suction power where you need it. If these gates are hard to reach they can be real pain to operate. [Cosmas Bauer] had this problem with his table saw, and created a …read more
Normally bubbles appearing in your extruded filament would be considered a bad sign, but it turns out you can now buy filament that has been specifically formulated to foam. [Stefan] from CNC Kitchen has doing some experiments with these bubbly filaments, and the results have been very interesting.
The filaments …read more

Most of us know that to get the best possible WiFi signal, you want there to be as few walls as possible between you and the Access Point. But that might soon change, as researchers at MIT have found a way to make surfaces increase signal strength. Called RFocus, the …read more
