IHMC demonstrated a few months ago how this #bostondynamics #robot can utilise LiDAR technology to create a map of the region it needs to go through, and then use an algorithm to figure out how many steps it needs to take to get to the other side. It's a significant achievement since this robot will act as a human avatar in perilous emergency situations. #enjoywatching

step by step instructions including chemicals, how to dilute them, laminating the board and even how to quick solder SMD components in 1 minute. All the credit is going to the author of the YouTube channel. and all the info. in this post is just copied from his description link of his YouTube channel.

Learn to fabricate Single Sided PCBs at home! Prototype PCB fabrication is one of the essential skills you must learn in electronics. Instead of using breadboards and perfboards, custom PCBs would make any project smaller and more compact! All the credit is going to the author of the YouTube channel. and all the info. in this post is just copied from his description link of his YouTube channel. PRESENSITIZED PCBs: Also known as photopositive PCBs or photoresist PCBs, are regular PCB copper clads, layered with a light sensitive paint or film. Once exposed to light, the paint would dissolve in the developing solution, while the unexposed areas would remain undissolved in the solution. This forms a Mask on the clad. When the developed PCB is exposed to an etchant, the masked areas would remain in tact while the unmasked areas would dissolve on your etchant, thus forming a copy of your printed PCB artwork. WHAT PAPER AND PRINTER TYPE TO USE: - You can use an injket printer for this type of PCB fabrication, no need for toner printers. - I use regular Short Bond Paper (Letter 8.5x11"). You can use parchment paper or inkjet friendly films for better fabrication quality. BETTER THAN TONER TRANSFER METHOD: Toner transfer method has been the number 1 go to in homebrew PCB fabcrication, next to the sharpie method. Toner transfer has its own limitations. One, is that you would need a toner printer, common inkjet printers simply wouldn't work. Second, as your line traces gets thinner, it would be more difficult to transfer the toner prints to the copper clad. Presensitized PCBs on the other hand creates the sharpest lines of all the homebrew fabrication methods. This is perfect for smaller circuits that involves SMT (Surface Mount) components. I use this method for building PCBs with line traces reaching down to 10mils (0.254mm). You can go as thin as 5mils (0.1275mm), but you would have to use inkjet friendly acetate. _______________________________ Instructable Tutorial: (https://www.instructables.com/id/Sing...)

This video demonstrates how to achieve repetitive jumping locomotion with the quadruped robot SpaceBok at lunar gravity. The robot uses a reaction wheel to control its attitude and parallel springs in the legs to jump efficiently.

To simulate the texture of virtual objects, gloves today use an array of tiny vibration motors. Like with pixels on screens, more motors means a higher fidelity recreation of the feel of virtual objects. Meta says traditional mechanical motors are “too big, expensive, and power-hungry to render realistic haptic sensations”, so four years ago it tasked its researchers to start work on soft, pliable actuators made of “entirely new materials”.
