Development and Control of a Two-wheeled Inverted Pendulum Robot

How can I get started quickly designing, building, and controlling a two-wheeled inverted pendulum robot with little background in electronics or control systems?

Start with an existing open-source balancing robot design instead of trying to invent everything from scratch. The Elektor OSPV1 project includes an article, open software, and an optional complete hardware set you can buy and modify [#21663955][#21663957] As a control reference, look at the Microchip application note linked in the thread [#21663959] If you want the simplest possible proof of concept, one reply suggests a 555 timer with CDS cells, and notes that an analog design can avoid using a microcontroller; the posted explanation also mentions using AC light-tube pulsing in the sensing circuit [#21663961][#21663962] It may also help to team up with an electrical engineering student so the electronics and control parts are covered alongside the mechanical work [#21663958]

Requesting guidance on inverted pendulum robot design
Post #1 21663954 01 Oct 2012 10:23

I am a Mechanical Engineering student, with no substantial knowledge of electrical engineering or control systems, and I am undertaking a project to design, build and control a two-wheeled inverted pendulum system. This would be my very first construction of this kind and i am oblivious of the best way to go about this work, and the materials to use, and how to design and implement the controllers involved. I chose this project because of the passion I developed over time for mobile robots, but with little knowledge of what to do, I am asking for your help on steps to take to achieve my very first bot within a short period of time.

Thanks

Hi there,
Never build one but several times i wanted to do.
My last resource is a link to a magazine that made a open source project.
they have the article and software open source that will help you, if you want buy the complete set hardware and the free software.
Because it is open source they want you to alter.

You also might consider teaming up with an electrical engineering student.

Or- You could go ultra simple using a 555 timer and some CDS cells...

That is a very simple and smart design.
and yes it avoids money for a micro controller.

The link does not show direct the schematic but if you Google the designers name you find it here.

In order to explain he is using a ac light tube, the ac light pulsing is used in the electronic part.

I wonder if you could simply drive 2 servos (in parallel) so it could be a 2-wheeled 'bot'?

But what balances it on those two wheels -- or is the max radius of the wheels longer that the greatest vertical dimensional extent of the body--a body that likely hangs from the axle with enough weight to overcome torsional friction in the barrings?

Topic summary

A Mechanical Engineering student seeks guidance on designing, building, and controlling a two-wheeled inverted pendulum robot with limited knowledge in electrical engineering and control systems. Responses suggest leveraging open-source projects such as the Elektor magazine's open source hardware and software platform for inverted pendulum robots, which provides schematics and control code that can be modified. Collaboration with electrical engineering students is recommended to address control system challenges. Additional resources include a Microchip application note on balancing robots and a simple analog balancing robot design using a 555 timer and CDS cells, which avoids microcontroller complexity. The analog design employs AC light tube pulsing for electronic control. Discussions also consider mechanical approaches like driving two servos in parallel, though questions arise about the balancing mechanism and the role of wheel radius and body weight distribution in stability.
