Hi,
I'm doing research on the construction of a robotic arm. Not something big but it must be functional not some cheap plastic kit. I was thinking more along the lines of the arms available from crust crawler.

How difficult is it to build (design) such an arm, rather than going the kit option. As I'm an electronics / computer engineer mechanics might pose a challenge.

Cheers

Re: Robotic Arm

HI Slayerza,
remember me? The one having problem with the OrCAD Layout. I just saw your mechanical problem here. Actually mechanical is not as difficult as you think, as I am the mechatronic engineer :D Pls specify with type of robot arm you would like to build and what is the size? I mean give me the 3D Cuboid approx. dimension. I will help you as much as I can.
 

Re: Robotic Arm

Hi,
Well I don't have a detailed specs as I am just toying with the idea. The arm I had in mind is something similar to the kit sold by lynxmotion. So I'll use that as a starting point.

As I am a electronics (RF) engineer some of the mechanicals are tricky the actual control is not a problem to me.

Thanks for your help
Cheers

Re: Robotic Arm

hi,
I am now working on Pick and place robotic using arm controller.
can anyone please help me.
 

Re: Robotic Arm

Can any body please help me.
How can we control the motor speed using micro controller(means through pgm) with out pwm circuit
 

Re: Robotic Arm

an arrangement with a few servo motors will help..
and a basic pic or arduino board can reduce programming..

Click to expand...
basic know how can be made by using arduino, it has 4 pwm pins. the pulse duration can be changed by changing the delay in the program. the output can be given to an isolator (opto) and wire it to a driver (motor driver l293d)
