I thought they were satellites from the start. You had 2 objects travelling at the same speed on parallel courses AND THEY FLEW STRAIGHT. When did you ever see bugs fly dead straight let alone parallel to each other?

@ngrey5092 Good point its in that area of metal shaping but its closer to folding and what's done in a press break. They are all part of the same basic principle of cold forging thin sheet.

@HingleMacCringleberry There's also another Edge Precision vid where he starts with a 930lb blank that machines down to a 133lb part. That's 797lb (over 85%) of the raw material is removed as waste. the title of that vis is "830 Op 1 Cad Cam" The waste isn't a problem its a matter of what they do with it.

@404Xyz Where do you get that figure from?? Didn't hear that it was doing about 8kms. That's around Mach 23.5 and there's nothing we have that flies that fast and certainly not at 100k feet. BUT the 550km orbit where Starlink flies has an orbital speed of 7.6kms which is probably why Destin first thought of Starlink.

AEROSPACE ENGINEER HERE: I have spent most of my career in control systems, automation and robotics. I once worked for the Australian agent for Kuka. I have also worked in metal shaping machinery - presses, folders, and roll formers. THIS IS ONE OF THE FEW TECHNOLOGIES I have seen anyone present on the internet that genuinely impressed me. That's in part because I understand how hard the kinematics of syncing 2 robots like that is and partly because I know how hard shaping metal in that way can get AND YET they have combined both into one system. Thanks or showing. OH YES - Please don't get close to active robots like that again UNLESS YOU ARE GOIGN TO WARN VIEWERS. Despite all the advances robots are still incredibly dangerous and its easy for people who DON'T UNDERSTAND to think the robot can see them. Many years ago I actually had a very, very close call when a delivery driver simply walked in the side door of our workshop. He did not call out to me and simply walked up to the robot that was on an elevated pedestal and stood under the gripper. At that moment I had my back turned and was looking down at the programming pendant. The first I knew he was there was when he suddenly said "Gee this is impressive!" ALL THAT KEPT HIM ALIVE was that my finger was NOT on the dead man switch. As I tried to tell him how much danger he was in he simply said "Can't the robot see me!" So please keep your viewers informed about the dangers of automated machinery.

repentandbelieveinJesusChrist9 Hey buddy, PEOPLE LIKE YOU are exactly why the majority of people these days DO NOT consider the bible as anything of value. You FORCE your way into other people's conversations. Jesus NEVER DID what you just did and he never gave you any instructions to do so.

@OB1canblowme There's not a lot of use of harmonic drives in robotics except in smaller robots. Mostly they use cycloidal drives. Kuka use (or they did when I worked for a Kuka agent) ZF manufactured low backlash gearboxes of various types. There's actually nothing that's genuinely zero backlash. There's just systems where the backlash is so low that its negligible. One of the Kuka integration specialists that does automated QA for companies like BMW has this amazing version that self corrects for temperature and other factors. If you want to see a really interesting vid on a system with insanely high accuracy the YT channel Machine Thinking has a vid on the coordinate measuring machine at NIST. Its so sensitive that turning on the lights affects the accuracy and when people actually go in the room it to do set-ups it can take hours for the temperature to restabilize.

@OB1canblowme I forgot to say I know an application where harmonic drives dominate. On space probes for things like cameras. Its because they don't require lubrication like cycloidal boxes do and they weigh a lot less.

@hanswerner321 Yeah but if have ever been around die making you'd know how time consuming that is. With this system you can design something and then just get it made right then. If you want to press some of these parts it takes weeks to do all the machining of the dies. Some of these parts would need a collection of progressive dies and that's a lot of machining. Its one of the main reasons car companies don't seem to change much from model to model. I used to work in the Australian auto industry and spent time in pressing plants. You'd be amazed how many parts go from car to car with almost zero changes because its just to costly to make new dies every time. Its why so many famous sports cars had all sorts of things from the spare parts bin. So for low to medium manufacturing this would have advantages BUT for serious mass production where you're making 1,000s of cars a day you're right its too slow.

@kyleteal5888 Your right. The basis for this is the sheet metal forming the body shop guys do with an English wheel where they have 2 rollers with slightly different shapes that they use to shape fenders, hoods,...etc. But they also include the the methods used in high end metal folders and press breaks except this is a point load system not a long liner tool.

@scottricketts2088 Can you and all of the other non-engineers PLEASE not throw AI into every conversation as if its some magic panacea for every technical issue. ITS NOT. MOST and I really do mean MOST of the reports of people using AI is just nonsense and hype. Its the current way for research projects and start-ups to get more funding. Just tell the ignorant clowns you're including AI in the project and they can't throw money fast enough.
