 8) Cool!   8)
I looked over your project, what you wanted, and then the link of the project.
From first glance, not to oversimplify your project, but is this it:
keep the inverted pendulum upright and an algorithm to maintain its position?
If this is so, then I have a shake and bake idea for you. Parallax sells a balancing
robot
kit, that maintains a standing position on two wheels. May be worth your time to invest in looking this up. The program, parts, and algorithims are built in, and may offer you an option which saves time, money, and learning curve. Please provide feedback if I am going in a wrong direction. :'( Keep me posted..... ;D

Axon Series: What is this thing?

The Axon has a built in bootloader to let you program using USB, no need for a separate hardware programmer.
Awesome! I had some difficulty programming the Axon, so I went ahead and bought
an STK 500. I will have to delve more into the software interface in order to program the Axon directly from the PC. I know the answer is in the tutorials, and a matter of
making the proper adjustments in my computer. Thanks!  ;D ;D ;D

Hello!

My name is Jelle Deruyter, i'm a last year electrotechnical engineer student from Belgium and I'm currently doing an erasmus programme in Hungary, Miskolc.
During this programme I have to do my final assignment on designing the power interface for an the inverted pendulum. (http://www.ict.com.tw/AI/Amira/amira/lframe_e.htm)
There used to be a actuator for this lab expirement but somehow they lost this (dont ask me how this is possible). I only have to design a power interface for this in order to be able to control this system by a microcontroller, pc or plc.

The problem is that my studies where more focussed on energy/high voltage subjects and so I only have the basics of electronics. But at the start of the semester I thought I was goeing to be able to do this thesis. So I started with a literature study of all the components, their voltage requirements, the input output signals etcetera.

But now I have to design the power interface for this. And I really have no idea on how to get started. I started reading things on the internet and ended up on this site. I read a lot of helpfull things here and I start to understand more and more about control/robotic engineering but I'm still a big noob.
I am not asking you guys (and girls) to design this power interface for me, I just hoped that some one could explain me how to get started with this. I learn fast, so once some one helpes me a little bit I think I can finish this by myself.

Maybe the following information can help to understand what I have to build. In this system there are;
- 2 incremental encoders used to measure the position of the chart and the angle of the pendulum. They need 5V DC Supply and have a 5V analoge output.
- 2 proximity switches that require a supply voltage of 15V, the output signal is an analog 11mA signal.
- 1 permanently excited DC motor that has a rated voltage of 42V, rated current of 5A and a rated power of 160W (i find this strange thought cause 42 * 5 = 210W..)
- The sensors are already connected to a 30-Pin connecter (The pinout can be seen in the attachment) Column c is not used here only inverted pendulum
- The Motor has a 4-Pin connector (Pinout can also be seen in the attachment)


On the site i found this page: http://www.societyofrobots.com/schematics_powerregulation.shtml and I think I will eventually have to build something like the scheme at the end of the page?


Thanks for taking time to read this! I really hope some one can help me out a little bit with this.  :)
If there is more info or photos needed to understand/help me out, please feel free to ask.
Sorry if this is not really robot related, but i think this subject gets close to robot automation?


Thanks in advance!

Electronics / GPS based Car using Roboduino?
« Last post by Adityav95 on April 26, 2015, 03:01:06 AM »
Hi,

I have decided to build an GPS based car using the roboduino micro controller. It reaches any coordinates I input without colliding into stuff. I understand that this has been done before, but the question I have in mind is regarding the roboduino board. I have heard in the past, the ATMega168 can't even store a program required to make a GPS clock that displays the time according to the time zone.

Question 1: Will the roboduino be able to accommodate a SKM53 or Ublox GPS module, a 10 DOF sensor and an SR-04 SONAR at the same time even if I use software serial etc? Remember that I will be using an L298 or similar motor driver on a hacked RC car as well.
Question 2: Additionally if it can support these many sensors, can it further support a bluetooth HC-05 module in case I wish to transmit the coordinates to the controller?

Thanks!
Aditya

Axon Series: What is this thing?
I have been delving deep into the programming end of the Axon  :D, and
have found similarities between this and the Beagle bone black.
Both have ARM architecture, and, it seems, that if you learn one,
you can learn the other(No time wasted). This is great!  ;D
An interface to the Axon from the beagle bone may be the perfect match, and would simplify programming in the more demanding robots.

Mechanics and Construction / Re: problem with weight and friction

 ;D Hello!
In reference to the issue you are explaining, as best I can interpret, I would
suggest using a physics book, specifically the REA solution series. They should have
a "free body diagram" for you to use.
To move a body at rest, on the ground, you have to overcome static momentum, and
once you have it moving, you use kinetic momentum, as best I can remember at this time.
I think the quick answer you are looking for is in the tutorials, in this forum. Good Luck!!  ;)
