Whats the velocity vs speed i wonder

Reminds me of a toggle lock in a firearm, such as the Luger.

Jealous :P

Wow great Projects I love it

Love how the video didn't show someone having to poke that top-dead-center situation to right it.Just a discrete cut.

Which motion profile is used?

This is a fantastic demonstration of snapping due to singularities

code pls? need

Maybe while you’re waiting for the robot you can quantize that beat - it’s out of timing calibration. Amazing to see your robotic calibration process though…

Yeah that's, indeed, fast.

why the wrist singularity will happen, using Numatics IK algorithm??

Wow.... the kinematic calculations for this have to be horrible to program 🙂 I couldnt even think of a way to calculate the coordinates 🙂

Another common singularity is the overhead singularity especially if the robot is mounted vertically or upside down.

how are the Dial guage readings utilized to find the Tooltip ?? Also, with this setup, getting the tooltip with Orientation is not be possible.... So for getting orientation as well, what setup can be made just by using the Dial guages??

frequncy of Calibration ,Means duration of Calibration period????

All the robots on this channel are ingenious

Is this something one could build using an existing 3d printer to make certain parts? This is way beyond my level of mechanical knowledge (I'm not an engineer of any sort). I was fascinated by this design and with many things like this for me interest leads me try things I don't fully understand. You could call it dreaming. I was wondering how you'd make a control system for such a thing as a hobbyist

Two passive arms seems just are mock arms. Otherwise it is standard RPP Cylindrical robot manipulator.

Hello, that is fascinating design, I appreciate the effort has been done there, I have a question thou, what is the weight to actuator’s size ratio, like how much the arms size should be and the motor torque to hold ex: 2kg of weight. Thanks

Great! What was the result?

oh look, 3/4 of a 3d printer

inconsistent tests inmho... plus many of these "tests" put the robot under mechanichal stress and loosing of performances. plus the robots acknowledge what the programmer said... the safety must be not based on the robot himself...

Hello. We have a UR10 and it kept running for 3 years with no problems. But now, the elbow has this singularity failing with the same program or with a manual movement. What could be the problem?

Exemplary editing, and display of the machine and software.

So cool to see the rendering then this actual machine... Props!

How does rotation at 0:08 work? - It's not shown in the see-trough part of the demo. Also I see only three actuations: Two rotational and one linear motor, but there are obviously four robotic DOFs: rotation, radius, height, endeffector-rotation I miss one rotative motor rotating the stack of all the 5 center plates as a whole …

The idea of the central linearly actuated push-bar to control the radial position seems ingenious! - For the sake of here for brevity undisclosed reasons I'm thinking about adding some compact 3DOF rotational wrist on the tip of a SCARA type robot while keeping all the additionally needed motors in the base too. Thus I turned to parallel SCARA designs to have two paths to distribute all the necessary mechanical through joint motion threading to, thereby avoiding to have an excessively high stack of belts (or chains) on a single-arm-path. The central push-bar adds a third path and helps further in "de-congestion" of the two arms. - Keeping actuation for the z-axis in the base (in contrast to what is presented here) and threading two actuations (rather than one as presented here) through each arm already gives three rotational DOFs plus one gripper-DOF at the tip. Nice. - I guess if things don't become to fragile one could even add a second or even third push-bar for yet more paths. But these would sometimes poke out at the front too.

I don't understand how the upper motor moves the bottom gear. How is it connected to it?

Great video! Can you tell me where to get an end of arm tool like that ?

Hello, I have a question sir. Is there a danger zone in this robot, I mean when the two arms get touched between themselves. If yes, how to avoid it. Thanks . Great work by the way.

what platform did you use to programm it?

Bonjour! Ravi de vous rencontrer mais je ne parle pas bien français donc j'écris en anglais, s'il vous plaît pardonnez-moi. Je suis étudiant en robotique en Corée du Sud et je voulais vous poser deux questions sur votre vidéo sur (ruclips.net/video/BNP74352vhg/видео.html). Pendant le processus d'assemblage des blocs lego, comment avez-vous réussi à reconnaître la position pour poser les blocs lego ? 1. Avons-nous d'abord inséré tous les petits blocs, puis trouvé les coordonnées de chaque bloc ? 2. Le bloc est-il assemblé après avoir calculé la valeur des coordonnées du Lego à insérer arbitrairement en premier ? Merci d'avance pour votre temps et votre aide ! --- Bonjour! Nice to meet you but I am not good at speaking french so I am writing in English, please forgive me. I am a student majoring in robotics in South Korea and I wanted to ask you two questions about your video at (ruclips.net/video/BNP74352vhg/видео.html). During the process of assembling lego blocks, how did you manage to recognize the position to put the lego blocks down? 1. Did we first insert all the small blocks and then find the coordinates for each block? 2. Is the block assembled after calculating the coordinate value of the Lego to be inserted arbitrarily first? Thank you for your time and help in advance!

please show me how to speed up robot?

less cost than a manual calibration with only manual laser tracking 👍

It's only 4 bars moving , not 5 !

Should have called it Iron Mantis
