First Time Attempt at ANYTHING
« on: December 18, 2011, 02:07:34 PM »
Hello, I had an idea the other day of a project that could educate me in the field of robotics. I want to design a robotic hand using servo motors. These motors will not be controled with buttons or switches but with a program. The hand will display the hour of the time by raising or lowering fingers. (I.E. just your index finger raised will be 1:00). I also wanted to include a simple screen that read off the minutes. I was wondering how to control all of this? Is the control and program seperate entities? As you can tell by the name, I am completly lost in this field and would like a slight push in the right direction.

Thank You

Matt

Hi,

The hand will display the hour of the time by raising or lowering fingers. (I.E. just your index finger raised will be 1:00).

If it's supposed to be a binary clock, don't demonstrate it between 1:59 and 3:00 (a.m. or p.m.), unless to someone you really hate (preferably someone smaller than yourself) ;)

Some nationalities may not like it from 2:59 to 4:00 and yet some will find 8:59 to 10:00 a bit offensive.
Call it a World Clock and you can P.off people day and night ;D


I also wanted to include a simple screen that read off the minutes.

Simple is good... What do you call "a simple screen"?
Two 7-segment LED displays would be better/simpler than a screen.


I was wondering how to control all of this? Is the control and program seperate entities?

The program controls it all.


As you can tell by the name, I am completly lost in this field and would like a slight push in the right direction.

Here's a push: Start with a single finger and make that work as you want before you proceed.


You need some sort of a microcontroller board to stuff the program into - do you have one already?

Thats hilarious! Didn't even think about how certain times is pretty much telling people off. I do think that kind of screen would be better and maybe when i get more basics taken care of i can include a oled or somthing. I was looking at the Parralax B2 controller for the brain and it seems to have enough outputs for the job but thats the only reason i thought it was good, dont know if it could handle all the movements. I saw that hand on youtube and went to the website, the only reason i didnt keep with it was that it used a audrino controller i was looking at the Parralax because of all the educational support they have on their website.

Thanks for the replys, any and all advice is taken with a smile! :)

As i am doing more research, I am finding myself confused when choosing between a Parralax Basic Stamp or a Arduino microcontroller... I am going to need to have time capabilities and in addition control a screen. Why didnt i start doing this when i was younger... :(

Hi,

I am going to need to have time capabilities

You could add something like this RTC
And with the Arduino you'll be able to get a larger amount of example programs and help in general.
