ROBOT trajectory

Hi all!!!

I'm simulating the trajectory of an ABB IRB2400 robot and I'm new to the field.

Have any of you ever simulated the trajectories of a robot with a 3D sketch? And is this possible?

Thank you for your answers.

Have a nice day.

Hello Olivier,

I recently did the simulation of a robot process to make a presentation to a client. I didn't use the 3D sketch but the constraint pilot tool which, in principle and in my opinion, is great for doing this kind of thing.

On the other hand, I have 2 points to note.

1) I have been confronted with bugs during my work and I have sometimes lost a lot of time. The bugs mainly concern constraints that are reversed and force you to take over all the positions. In short, for me, the handling of a robot with this function remains delicate. A ticket is open but not again on this side for the moment. Maybe other people here can provide their solutions.

2) It is necessary to configure the robot assembly so that it can be operated by the stress driver.

Regards.

Steve

Hello

I haven't done it yet but I don't see why it shouldn't work. Just leave it free to move but still with stop constraints (rotation of the bottom and the two joints) then constrain the front of the arm with your 3d sketch and you will see the movements it accepts.

Thank you for your answer.

I started to do my simulation with the constraint drivers, it's a very well done tool. It's a bit long to set up when you have a fairly complex trajectory. That's why I wanted to go through the 3D sketch trajectories.

I'm going to keep trying and I'll try to show you the result.

Good night.

Good evening Steve

You just need each part of your robot to be controlled in a 3D spline and especially a point on the robot.

You need as much spline as you have movement in your robot.

Be careful because there is a mega trap when the robot spins on its base, all your splines go into a lollipop. So you have to make a fake piece that you attach to the base of the rotating bottom piece. And that you draw all your 3D splines from this part.

This will simplify the PB a lot.

I think that a sequential analysis is the most suitable for a motion study such as a robot arm.

The actuators act as in real life and are triggered as soon as sensors detect the presence of the room.

In the SOLIDWORKS tutorials, there is an example with welding robots.

See these videos on the subject:
