Mechanics and Construction / Re: Robotics Job Market for Mechanical Engineers?
« Last post by mklrobo on Yesterday at 06:07:30 AM »
 ;D Hello!
I have not had experience with this event, but I would hazard a guess, that you are right,
in the fact of ditching the mechanical engineers after the body is prototyped. This is why I chose to
pursue focus in electronics and mechanical engineering. Companies have to streamline costs, so
I assume they will eliminate any jobs they think are not needed at the time. Unfortunately,
the product suffers, (My opinion), because you will always need adaptations; so when they get rid of
the mechanical guys, who is left to help in the upgrades?   ;)

Mechanics and Construction / Re: Servo or geared motor with encoder?
« Last post by Joseph Thurlow on Yesterday at 02:15:49 AM »
ProgressiveAutomations - Wow, I thought GPS were very accurate. So then if expensive GPS modules are accurate to 1 cm, how accurate would be the average GPS?
I plan on using the robot indoors so slipping wouldn't be a big problem.
I also plan on having at least three ultrasonic sensors on my robot.

markmac - Hmm sounds interesting, if you can, please keep me updated on how your robot progresses. What sensors do you plan on using for it?

Thank you both for your help.

Anybody know what sensors a robot would need for me to be able to track it on a computer relatively accurately?

Thank a lot cyberjeff. I really appereciate your help. I will have a look on the resourses you provided and I am sure it will work for me.

Mechanics and Construction / Robotics Job Market for Mechanical Engineers?
« Last post by Agent Hal Lee on September 03, 2015, 07:10:44 PM »
Based on my job search for the past few months, it seems that all the robotics-related jobs are software-related, with few if any for those concentrating in mechanical engineering. I am more interested in the hands-on hardware and mechanical side (i.e. thinking about how the human arm moves and translating that to a prosthetic/robotic arm), and yet there is so little to offer in the job market in that respect. Places like Kiva or Rethink Robotics (makes Baxter) seem to hire MEs just to prototype the body, and then ditch them afterwards, leaving only software/computer science job openings. Is this really the case or am I missing something?

Thanks but what controller should I use with motors like those?

Software / Re: Interfacing PS2 Controller with AVR
« Last post by mklrobo on September 03, 2015, 05:24:56 AM »
 ;D Hello!
 I think someone has already interfaced a PS2 to a CNC machine, somewhere in the forum. The
Axon has a great library with dependable functions; for me, I just need to know HOW to program it.  :o
Still working on it.  ;D

Thanks for your reply.

I understand your concern, and I agree.

Assuming that I follow the way you mentioned, and lets say I need 2 servos and 2 steppers in the project,

would I need 1 or 2 arduino plugged in the PC in order to controll the motors? Moreover, are these coming with relevant



Just one. An Arduino UNO, by itself has 6 PWM outputs.

An Arduino Uno is a great starter board. A wide variety of stuff plugs in or runs off. Here is a stepper servo shield plugged in on the UNO:

(Servos don't actually need a shield, steppers and motors do)

and here is a UNO:

You program it through a USB cable to your PC (or Mac , or *nix) and you may wish to use Eclipse with Arduino extensions but I just use  the native IDE:

Windows requires a driver .inf

Clones are widely available on Ebay and very cheap. Even Microcenter has UNOs for under $10.

windows drivers (or libraries)  that would help me integrate them with the main software application that will run the whole project?

I mean I would like to use ready software (C++ works fine)  for this..

If you could sent me some links so that I would fastly deep on this, it would help a lot.

Kind regards


There are other options but Arduino has a vast support network and is very easy to get started with. The learning curve is short.

I suppose if you are a windows developer everything looks like a windows solution:

https://www.pc-control.co.uk/howto_servo.htm

I wouldn't go that route though. Connecting servos to a microcontroller is no big deal, microcontrollers typically have many inputs and a variety of devices that plug right in. In the Arduino community they call them shields. Assuming you are fluent in C++, you can dive right in.
