Theres somethin like that already, a slomo clip in which a high speed camera tracks the path of a RailGun bullet hitting a target. Those things moves faster then sound but the camera was able to track n follow it.
I gotta say the most impressive part is how there is no vibration. Did you use cables with low elastic modulus? Even then the angles of the cables resisting movement is going to be different for every final position xyz. Then if you are tensioning the cable you have to figure out the max axial stresses on the cables, change in momentum. Loading that specimen is gonna be a pain tho. What was your biggest challenge with the project? Good work btw man.
@@JamesZJi Vibration in the center module, there is zero wobble and this is pretty difficult to achieve. My guess is those nonelastic cables are tensioned pretty good to achieve fast speed, precise actions without wobble.
High tension/preload, high E-modulus combined with a probably rather high damping factor of those braided multi strand strings compared to a single filament kind of string, light weight of the moved object and last but not least - lots of cables constraining movement in every axis. Doesn't seem that impressive to me, rather what I'd expect from engineering well done!
@@cjeam9199 This effector can also lean in two axis which can be seen in the video so it's 5 axis. Looking at the string arrangment there might be possibility of twisting around vertical axis so maybe even 6.
@@Vajdera True, the strings must support movement in all axis because it needs to be stabilized in all axis. I don't see any winch with two cables to fix a particular rotation. But the rotation on the vertical axis is probably very limited and not useful.
I've seen lots of videos like this lately but I have yet to see one where the mechanism actually does something useful. They all just seem to show off how fast and agile they can be but never show the work they can do in machining or w/e they are useful for.
This is an instance where I would stress the difference between accuracy and repeatability. There are a bunch of elements that detract from the accuracy of this machine. And unless this machine is kept at a consistent temperature, the repeatability across time will be poor to my standards.
@@oneeco kinematics is the physics/engineering technical term for "geometry". Basically, if you want the object at coordinates: x, y, z the kinematic equations spit out what the cable lengths: a, b, c, etc. should be. Calibration just means tweaking the "perfect world equations" to match the real world machine. An everyday example of calibration would be "zeroing" an empty scale that may show a "false reading" when you first take it out to use it to weigh something.
This is capable of moving as fast as a fly. Quite impressive. But unlike a fly, it goes like this. Go, reach some point, stop briefly, go again somewhere else. Can it be done in such a way to smooth the curves instead of taking turns by brief stops? What i'm trying to say is - can it do movement that is not just straight line, stop and go another straight line? It take turns by joining straight lines, instead of turning smooth like a car, plane or fly or something else. Also as second question, what are the intrinsic advantages such system provides over a gantry like system? Seems to me a lot of energy is wasted by not lifting vertically. When lifting heavy stuff like containers in a port, then such energy efficiency can put one out of business.
Movement is completly free. All cables can come above. Different kind of cable robots. You can use passiv elements. Like counter weights or springs. To reduce the power consumption.
@@ChristopherReichert Thanks. Do you have a video/white-paper/blog article/something which describes how to use this counterweights? I can't see how that would work. My reasoning is as follows: If you wanna lift a 3 ton object, at height 3 meters - and you apply lifting forces sideways not perfectly vertical, you loose more energy since the forces required are much higher, the tension is higher, - the vertical component of the vector is smaller then if you pull sideways compared to lifting directly vertically. And the higher the weight, the beefier cables you need to account for that. And when increasing working area in one dimension - the usual use case in a warehouse - like increasing the length for example - the cables diameter must increase, but a gantry cross beam structural requirements would remain constant. So increasing the length of a warehouse by 10x in a gantry setup - is just the cost of adding more rail, but the cables must also increase in diameter, not just in length, requiring everything else from pulleys to trolleys to be redesigned. This seems like a fundamental limitation of this system. As a solution you propose counterweights. Given that the engineering works somehow (not clear to me how at this point), Then when we wanna lower the weight - to be able to lower it, we must lift the counterweights, which defeats the purpose since is the same consumption of energy. Now it might be an advantage since one can use leverage - gear box etc, use a smaller cheaper motor etc, but the energy loss is the same - actually higher since gear boxes and such introduce inefficiencies. Compared to a 3d printer like thingy/a gantry setup - the lifting force is vertically applied which makes it more efficient. This system pulling sideways is not. And overall im trying to figure out if this system has any real advantage compared to a gantry like setup. Because cables are quite expensive, special purpose products, but I beams, square beams for making gantries are relatively cheap and readily available since are used in house construction. I think your work is great, i'm not putting down this idea - just trying to build a good intuition on where each principle can be used, and if there is any real advantage of using this system for my particular case.
Screw linear rails and ball screws, good old cables and pulleys are the future! At least, for light CNC tool loads where you don’t have a whole lot of weight or cabling leading to the tool. So basically only good for like a 5-axis CNC laser cutter, or other optical uses.
@@Flowxing Yes but this is not only about speed. This system here doesn't require the heatbed to move, in addition if calibrated right you would be able to print diagonally.
Ok on a serious note though, what would this be used for in a practical application? Obviously much technical work has gone into this just curious as to the purpose and end goal?
I think the main issue would be introducing the extra mass of a print head with a heater block, fans, direct drive motor and cables etc. Also, at some point you'll probably just be flinging melted plastic all over since it wouldn't have time to cool between layers, and the inertia of rapidly changing direction. Not to be all negative or anything, but I was just thinking about it. I think it's a neat concept, however.
@@nikolaivillitz6026 it wouldn't be moving as fast, it was probably just to show off the accuracy and tightness. The only thing i think would be the limiting factor would be that the strings would get in the way and perfectly horizontal movement would be harder
Not even close. Could not imagine what a pain calibrating this machine would be, plus the wires get in the way. It is easier and cheaper to build fast 3D printers other ways. Even an HBot would be a better option that this, even at large scale. This technology is limited to things like photography. Particularly football cameras

Very nice BUT!!!! ... I have experience with cable winding systems. The cable rubs against itself, once it creates enough wear it will systematically bulk and overlap itself on the winding drum. Once that happens - your entire function of tension in the winding and unwinding falls apart. IF!!! However, one were to coat that wire with say a plastic tubing and the Robot head is not heavy- you may have good results.
Hi Christopher, I am a mechanical engineering student working on a similar project for a class project. Had a few questions for you. What type of cables did you use? Where did you purchase your swiveling pulleys (or did you manufacture them)? What motors did you use? Thanks!!

Can you explain why you think this concept has no purpose? The prototype might not, but it can be repurposed to do anything that requires this sort of movement, only limited by your depth of brainstorming. By the way there are machines like this which move on a 2D plane at a much faster speed which built the components and quality control checked the solder points on the device you used to watch this video.
@@APioneerInTheSeaOfStars Are you triggered? This machine is a proof of concept and has YET to see a purpose...ergo, useless right now. Comparing a machine without purpose to a machine that is different WITH purpose is like saying you like Yoghurt but you eat a banana instead. In my eyes, something like this is too "complicated" and "flimsy" to see a true purpose. 3 dimensions, fast moving mass and cables = poor accuracy and lots of movement in the frame. There are fast moving belts and stepper motors like you say on a 2D plane that have less wear and have more accuracy. Again, this is a proof on concept and visualizing something that someone might find an application for. Who knows.
I dont know what it is used for, but if it is used for industry isn't there an issue with accuracy? Because after an extended period of time im assuming the cables need to be exchanged because they may or may not lose their flexibility or isn't it an issue at all?
Interesting. Fast accurate movement, but the wires themselves make most things I can think of not viable. It wouldn't work for CNC or 3D printer because while it can move the end effector accurately, it's still tethered to the corners so you would have to calculate collisions on the end and all the wires. It's like the intersection of multiple planes.
