Software / Help needed for algorithm
« Last post by msavazzi on Yesterday at 11:56:40 AM »
Team,
I'm new to this forum, so first of all I wish to say hello to everyone!

Second here is the reason why I subscribed: it's quite some time I'm trying to solve this challenge but I'm not able to. I want to build a robot that put in an area will cover all of it.
The area should be random and could include some "black spots".
simple forward and bounce will not work.

I've tried to search but I was not able to find anything... can you help me? can you provide me some guidance or help on what to search?

On the robot side I have no issue with motors, wheels, sensors, etc...

To make it simple assume that I have a bumper in front of the robot and I just use that to detect ostacles.

Thank you for your help!

Mechanics and Construction / Fluidic Based Actuators
« Last post by joeedh on August 24, 2016, 04:58:25 PM »
Hi all.  I'm a computer graphics engineer, and for years I've dreamed of building a small, compact robot with dozens (at least 24) of actuators (mostly for research).  Recently I've been trying fluidics out (with compressed air), and I was wondering if anyone else has ever done that.

The basic idea I had is to attach a mini solenoid valve (like from blood pressure monitors) to a fluidic valve.  The solenoid valve takes an air stream of, safe, 4-5 PSI, and uses the fluidic valve to amplify it to 20-30.  That then drives a pneumatic actuator.  I have a 3d printer, and I've managed to get a fluidic valve that seems to work (it works the way I want it too. . .but, not the way my books on fluidics say it should, heh), and I've ordered a little solenoid valve.

The fluidic valve, including the solenoid, works out to about 25mm x 55mm x 20mm tall, so about 1'' by 2'' by 1''.  I haven't decided what to do about the actuator yet (air muscles?  Disney's pneumatic rack and pinion setup? a pneumatic stepper motor?), but I'm planning to start with simple air muscles (because they are easy).

Anyway, thanks for any replies.

 :) Hello!  :)

     There are vendors advertising on the right hand side of your web - screen that may be of help.
I have looked at Lego - mindstorms at Toys are us; Mechanoid Madness posts, where you have a
cute robot to assemble. If you visit Youtube for Mechanoid Madness, you can find a slew of suggestions!
Good Luck, and have fun!!   ;) :) :D ;D

Mechanics and Construction / Is there any standard mechanical parts to make robots?

Hello
I want to build some robot packages for kids, but I don't know if there is any standard parts to make robots?

I mean some things like this photos:






What keyword should I search to find factories that make this?

Thank you !

Software / Re: kLib - searching for github contributors

 :) Hello!
I am a strong supporter of the Axon board. I love the design of the pinouts and general attributes. I get frustrated
with it because I can not get access to program it.  If we could use yours in place of the processor, or have a dual core
STM32 for the brains and the Axon for the physical interface, that would work. Ideas increase immensely if you have
an open, intuitive IDE for programming; People will program it.  ;) :) :D ;D

Really interesting. I've never seen a multi-core MCU  :D. For now, I do not know what shape project will have in the future . We'll see if it will be useful! I do not know the language FORTH so I can not say if he could compete . It seems to me that the raspberry is designed for some other purposes than boards which use stm32. Also I think it's a great idea to put this processor into some version of Axon board . ;)

Not really robotics related but I had been researching security cams to use on an RV lately, so I figured I should share what I've found...

If you have wifi near your vehicle I'd recommend something like this:

Otherwise this should last 7 days on a charge:

Hunting cameras should also be good...just make sure it doesn't use flash, or they'll smash your window in to steal the camera:
