Axles/Slip Rings/Angle Sensors

[X89codered89X]

Hi all. I have a couple questions for those familiar with mechatronic stuff.

I'm looking for some type of [(angle sensor) + (axle) + (Perhaps a slip ring as well)] all in one. The slip ring is necessarily going to be in the final project that I'm using it for but I could get a slip ring separately. I was particularly concerned however of how to attach an angle sensor to an axle from two separate.

Regardless I need some way to combine a slip ring (electrical contact through a rotating connection) into an axle along with an angle sensor. How would I go about doing this.

Moreover... I don't even have a good idea for what to buy... what sizes... what tools I'll need to build this thing..

The project is a controlled double pendulum... I'm trying to control it to swing it up and keep it inverted...


here is a rough picture I drew of why I need such a complex [(angle sensor) + (axle) + (Perhaps a slip ring as well)] all in one:

Excuse the sloppiness of the drawing... It's a concept drawing only.

My intuition leads me as far as .. "Ball Bearings sound good."

Thank you for your post and interest in mechatronic systems. It sounds like you have an interesting project in mind with your controlled double pendulum. The combination of an angle sensor, axle, and slip ring can certainly be a complex task, but with the right approach and tools, it is definitely achievable.

Firstly, to attach an angle sensor to an axle, you will need to consider the type of angle sensor you will be using. There are a variety of options available, such as potentiometers, encoders, and gyroscopes. It is important to choose an angle sensor that is suitable for your project and has the necessary range and precision. Once you have chosen your angle sensor, you can attach it to the axle using a variety of methods, such as clamps, brackets, or even adhesive.

Next, for the slip ring, you will need to consider the electrical requirements for your project. Make sure to choose a slip ring that can handle the necessary voltage and current for your application. You can then attach the slip ring to the axle using a similar method as the angle sensor, or you can also use a coupling or coupling adapter to connect the two.

When it comes to purchasing these components, it is best to do some research and find suppliers that offer the specific sizes and types that you need. You can also consult with a mechatronic specialist or engineer for recommendations on the best components for your project.

As for the tools you will need, it will depend on the specific components you choose and how you plan to assemble them. Generally, you will need basic tools such as pliers, screwdrivers, and wrenches. However, you may also need specialized tools such as a soldering iron or a drill for certain components.

In terms of the ball bearings you mentioned, they can be a good option for smooth rotation and support for your axle. Just make sure to choose the appropriate size and type for your application.

I hope this helps guide you in the right direction for your project. Best of luck with your controlled double pendulum!
