BXD: Synthesis Ideas

Anonymous · ‎02-19-2019

Hello, As CAD Lead of FRC Team #4239, I would like to be able to manipulate and place all game pieces in the way each game requires them to. Such as Gears in 2017, or Hatches in 2019. Currently, you cannot place hatches correctly, and as a centerpiece in this years game, it is critically important that such a feature be implemented, especially as we transition into post-bag-day. This is a vital function to have as a simulator, and would markedly increase the usability of Synthesis as a driver's practice program.

I have now worked with three FRC playing field models, trying to export them into Synthesis. Every time, the field modeller/designer clearly did not know how a field should be designed so as to make it straigthforward to prepare and export to Synthesis. It would be usefull if a Field Design Guide was written explaining how the Synthesis Field Exporter works and what it expects to find in the field model structure and contents. For example: - gamepieces with different characteristics should not be modelled into the same Assembly; - field elements that rise or drop at a different height than the field floor should be modelled as a separate Assembly in the field; how to define spawnpoits into a field design (either for gamepieces or robots) etc.

As stated on the synthesis web page, the code emulator supports only c++ but i guess many teams, including mine are switching to python code. It would be awesome to add support also to python code

Camera from robot is real time, but real world one will never be. Would be great to enter an duration for camera lag in config so people could practice getting used to it. Thanks

Autodesk Synthesis should be able to play the role of a Roborio during a build and accept and load the built code into the Emulator. Right now, the Eclipse Build requires that a RoboRio be connected on ports 172.22.11.2 or 10.39.86.2 in order for a build to proceed. Thsi is most inconvenient, especially in situation where the team does not have a RoboRio to connect to every software development station.

When changing the robot spawn point, the Orient Robot pane should make it possible to rotate the robot around the Z axis as well as the X or Y..

Everytime I reset or change the Field in Synthesis (Version 4.2.0.1), the connexion with the controller (normally a wireless XBox Gamepad controller) is lost. The only way to re-establish is to exit Synthesis and restart completely.

Currently, it is only possible using the Driver Station Navigation function to move the Driver Station Eye Viewpoint left or right. It should be possible to move the Viewpoint up/down, or forward/backward to replicate a more realistic viewpoint for a driver.

My biggest gripe with any type of FRC simlator would be all the finer details which make real robots a major pain... such as each motor/system being inherently slightly different which often you need to tune out. The inertia/strength of appendages and how it effects rest of robot/game pieces. So any half decent simulation should have varying degrees of offsets to better emulate actual performance of a robot. I mean in a simulation maccanum and omni-wheel drive would never lose orientation but we all know what actually happens and it's these finer details which often are the real problem to deal with... Also another big gripe is i imagine the simlation takes speeds of motors as inputs, but that's not the reality at all. the PWM values you send are a force, a very non linear one at that, so the simulation would need a proper half decent physics engine to even just get that part right keeping in mind the current limitations. It's a very common problem to blow breakers under certain loads which the simulation would probably completely ignore. Also properly implementing the motor curve specs and weight(along with rest of phsyics engine) to be able to determine if a motor can even do the desired task it's being used for in the simulation. That's a lot more complicated than just a few parameters. In the end it comes down to a very good physics engine to be of any practical use to us. I'm not talking about the type of physics you see in video games either =p at least no fluid dynamics are required. (Originally from Reddit user sanels)

What support are you offering for simulated sensors? Encoders, potentiometers, limit switches, range sensors like ultrasonics, gyros, cameras (as Blake previously mentioned) Make it open source Simulate battery and electric motor dynamics effects Out of curiosity, what are you using as the physics engine?

A couple of weeks ago, I randomly found some of the plans we made for expanding the 5th Gear simulator. I'll post some of that and/or exchange some emails with you guys. With luck I'll find some API code I was working on too. A few questions to create some context..... If you imagine a typical (weak) school computer, can that computer simulate one instance of one complex robot at real-world speeds? On that imaginary computer how often can the simulation update (in real world, wall clock time), and how much simulated (robot's imaginary world) time would each update represent? Do you have TCP/UDP interfaces for exporting the robot's externally visible and internal state, and for importing commands to control actuators? To simplify graphics processing and computation in general, do you have a low fidelity mode for each robot? Do you have a Graphics-only executable for displaying multiple robots and game pieces on a field? Do you have an executable that can create an image (an updating array of pixels) that approximates what a robot mounted camera would see? What about scenery that would surround a field? The answer to all of the above might be "No". If it is, that doesn't diminish that you are in the process of doing something really special. Blake (Originally from Chief Delphi user gblake)

It should be possible to modify the orientation of the Robot Spawn Point in the Field Exporter. Currently, the robot is always spawned parallel to the field. I am encountering situation in which the robot needs to be spawned at an angle, for example on a launch platform located in a corner of the field.

In the Field Exporter, it should be possible to specify where the Driver Station is relative to the playing field. I am working with a field for an off-season event on which the driver station is located on the side boards instead of the ends of the playing field. Just like the Robot Spawn point that uses a CAD Work Point in the Field Exporter, it should be possible to create a Work Point locating where the Driver Station is. This may require that the Field Exporter recognize Work Point names to make the distinction.

Solidworks support? Seriously though, this sounds super cool. I'm going to have to learn Inventor for this. Sensor support would be the main feature that would be good, or just some way to add sensors. Basic distance sensors and encoders (CPR on wheels) would be really useful. Can the field have elevated portions, or just high-friction areas? (Originally from Chief Delphi user asid61)

How about an API with a non-GUI mode so that it can be easily used in automated tests? (Originally from Chief Delphi user SoftwareBug2.0)

Since each game is announced at the start of the year, it would be great if there was an authoring component to Synthesis, letting the system be updated to the new game as fast as possible. This way teams can practice with the current game and not only the ones from past years.
