Hello everyone,

maybe it can be justified by the German stereotype, but I hate to be late. So this is me being early…✌

Here is my submission: A Camera-Panning-Device that can tilt and swivel two webcams. The recording of the webcams is used in real time to detect objects via a MatLab-machine-vision-algorithm.

The MatLab algorithm passes on the pitch and yaw angles to the stepper motors via the stepper motor control in order to align the cameras to the center of the surface of the detected object. The position of the object in three dimensional space can be calculated by triangulation using the set pitch and yaw angles.

 

The design includes: 

• 2 webcams (Renkforce RFWC)
• panning device (equipped with four Nema 11 stepper motors)
• stepper motor controller (designed in Autodesk EAGLE for 4x stepper motor driver TMC2130)
• the found object of the object-detection-algorithm (represented as a transparent cube).

The panning device was designed using Generative Design (unrestrictive) and is optimized to increase structural stiffness and save weight, ultimately improving accuracy of the triangulation process. The result was printed on an SLA 3D printer. Here is me trying to remove the parts from the print bed and not destroying them (I only broke 2 of them):

One half of the device (the one I got of the print bed without destroying it) is currently being tested and looks like this:

About the mechanism:

The object (transparent cube) can be moved freely by the user, and the two webcams follow the objects area center via the camera pan mechanism (see screen cast).

Simple motion joints and additional components (hidden in the design) were used to construct the object alignment logic.

If the community is interested into more detail, I will gladly provide more information about this project (currently I am working on the object recognition algorithm and the communication between MatLab and the stepper motor control).

I haven’t made any changes to my design from the regional contest.

The CAD-files are zipped and attached, or can be downloaded from this link:

@HideoYamada  what an amazing design! How did you come up with the shape of the rolls!? The geometry is super complex.. I can’t wait to read how you designed those shapes! The 2 rolls intertwine smooth as butter! -great work!

@Anonymous didn’t know that was possible with Fusion …how did you implement the damping and the springs!? I am impressed by the dynamics in that simulation! Amazing result!

Thank you Autodesk for organizing those Community Games! And see those brilliant and interesting projects.

I am looking forward to get a deeper insight into the other designs!

Hello, everyone

I'm glad I got to the final.

A little modification has been made to the individual free aircraft of the competition works,In order to achieve better results.

The original design originates from people's yearning for and beautiful vision of the sky.

You can enjoy a free and safe blue sky.

Personal aircraft

The mechanical mechanism of personal free aircraft is mainly divided into three parts:

•  the overall framework
• chair, armrest, pedal
•  power structure (engine, wings, etc.)

Powered by four engines.

The wings are rotated to provide the lift needed for the vehicle.

[HideoYamada]

Hello,

Let me show you a mechanism to rotate the box that has never been seen before.

This mechanism was made possible by advanced 3D CAD and 3D milling machines.
The test machine was fabricated with a 3D printer and we were able to verify that it works as intended.

[johannes_kimmle]

Hello @HideoYamada,

amazing design! Could you explain to me how you calculated/designed the geometry of the rolls to rotate these boxes please...

This just blows my mind and I have no idea how you have done that! Have you used any additional tools? -like a specific algorithm which calculates the shape!? or any simulations?

-Thank you

Johannes Kimmle

[HideoYamada]

Oh, failed!

I'm retrying...

Let me show you a mechanism to rotate the box that has never been seen before.

916f0136-39d5-4cba-abd4-05bb62d267e5,

This mechanism was made possible by advanced 3D CAD(Yes, It's Inventor!) and 3D milling machines.

 

The test machine was fabricated with a 3D printer and we were able to verify that it works as intended.

The finished version of the screw is optimized for conveying materials and is even more complex.

 

Finally, I attach an animated video of the operation at real speed. Please take a look!

Thanks.

Hello everyone!!

I'm happy to advance to the finals.

The Fusion ball game begins.

Anyone using Fusion 360 can join the game.

It's easy to play.

Just drag the mouse.

The items changed for the final round are equipped with meters for the X-axis, Y-axis, and Z-axis.

For more information, see “How to play the Fusion ball.pdf”.

The feature of The fusion ball is.

1: You can use the “gear shift” “steering” “lever” to move the Fusion Ball in three dimensions.

2: It is equipped with a next-generation compressor (small size, high output, low noise, energy

saving).

3: Olive oil is used as the lubricating oil in consideration of the environment.

4: Anyone can easily customize.

5: This is unfortunately a fictitious model.

If you are a Fusion360 user, please try it.

* Please do not play during work.

We would like to thank AUTODESK for giving us such an opportunity.

Inventor 2020 or later can create a twisted solid sweep. Without this function, it would have been difficult to make the shape of the screw.

(I started this study before Inventor 2020 was released. Since Inventor 2019 did not have such a useful function, so I had to model by the custom macro.)

The model of the screw was simplified and re-modeled for entry into this contest. The original tool path for solid sweep was written by a complex equation curve to gently and continuously vary the lead of the screw.

[johannes_kimmle]

Thank you @HideoYamada for your explanation!

The twisted solid sweep command is a powerful function! Thank you for that hint.

I don't want to think about how you did that without this command in version 2019! -great job!

...had a look at your "freeradical" website you attached -looks like this is not your only amazing project you are involved at -great stuff.

Greetings to you in Japan!

That's not a highly recommended approach. See the attached video.

But if the number of divisions is small enough, it looks smooth.

Hello everyone, a sample system with a pizza oven. The mechanics (robot) can be controlled in all axes via iLogic (without entering angles), and it can still be set down and driven with pinpoint accuracy.

Hello!

I present to your attention the work on the study of the car movement with a trailer on bumps.

To conduct the study 3D models of cars and a trailer were built on a scale of 1: 1. Car bodies were developed with the help of surface modeling in Autodesk Fusion 360.

Suspension models were built in Autodesk Inventor 2020. Trailer frame was designed using the frame generator.

The loads on the front and rear axles of the vehicle are concentrated in a frame weighing 1900 kg.

The functional calculation of the main car and trailer suspension parameters was performed for the suspension's dynamic simulation in the Autodesk Inventor. The calculation was made for each wheel depending on the weight distribution. The main parameters of the suspension are the stiffness of the elastic elements, the damping coefficient of the shock absorber and the static deflection of the suspension. There were selected stiffness, damping coefficient and friction coefficient for each tire.

The cylindrical connection was added to the front suspension struts. There was added "3D contact" to all wheels with tire parameters. There were calculated Spring / shock absorber / jack power connections with individual parameters to the front and rear suspension. Torque was applied to the front wheels. Gravity was set.

Using the graphical output device, there were obtained the graph of the wheel displacements and the graph of vertical body’s displacements.

Here you can observe the video of the dynamic simulation:

To sum it up, we have an opportunity to carry out kinematic and dynamic analysis of the car suspension due to Autodesk Inventor. Moreover, the visualization of the research results is possible. The results obtained can be used to calculate the strength and durability of vehicle suspension elements. We are able to realize our design potential due to the program Autodesk Fusion 360.

Hello,

Thank you for allowing my entry to be a winner in the Preliminary round. 

I am going to explain the project from the beginning and show the improvements made after the first submission.

My first idea to make such a model came through DIY projects (made of cardboard). The initial dimensions were taken from https://www.youtube.com/watch?v=XYdF-B0r_V0

I have used the CAM mechanism. Fusion 360 has given the tools to visualize various ideas for creating various forms. 

Here's the Screencast. 

A Drop of love is an Automaton / Mechanical toy. The message that I would like to give through this model is given at the end of this description.

Variations of the product

1)STAR

2)STEP

3) Parametric: I tried to make this model parametric. For example, the support size can be changed using user parameters. Size of the cam and gap between them can be changed through parameters. This gives way to easily change the pattern flow of the ripples. Also, a template file has been made where the top shape can be changed. So, a user can get creative about making automata toys easily.

I have not yet manufactured any. These files can easily 3d printed, CNC milled or lasercut from Fusion 360 software. Stress analysis can be done before that which is pending.

This product can be a stress buster, a Christmas gift or a showpiece. For me this is a reminder of love and forgiveness.

A drop of love and forgiveness can create the same ripples around them and make the world a better place to live.

I would like to see this product at home, to remind that relationships can be maintained through love and forgiveness, at the office to reconcile with your team, at every country’s President’s desk to solve the international issues through dialog and save the lives of soldiers and establish world peace.

So, the message is 

A drop of love and forgiveness can create the same ripples around them and can bring inner peace and world peace.
