I am Saravanan Natarajan from India. I am doing a project in which EMG based actuation of robotic arm has to be accomplished.For this purpose I will be using an EMG sensor attached to human hand.An Emg signal thus obtained is amplified using Instrumentation Amplifier.The output of Instrumentation amplifier has to be given as analog input to SSC 32? Is it possible?
Please reply as soon as possible.
The SSC-32 has four inputs that can be used as analog inputs. However, the data values returned are only 8 bit resolution, so may not be useful for your application. The SSC-32 does not have any way to process the input data, so you need to have it connected to a microcontroller for processing.
Normally you would want to use a microcontroller to process the analog input data directly, since the resolution will be much better. You would need to write a program for the microcontroller to process the analog input data from your sensor(s). Then you would have the microcontroller send the appropriate servo commands to the SSC-32 to move the arm.
The Basic ATOM and ATOM PRO microcontrollers both have 10 bit ADCs. The Basic ATOM has 4 and the PRO has 8.

I have bought this ssc 32 from robotshop.I need assistance from the corresponding people on how to switch on the servo controller and how to use them as ADC?I have bought it along with RIOS Software.My project is EMG BASED ACTUATION of ROBOTIC ARM.I have INSTRUMENTATION AMPLIFIER through which I have to interface it to a computer.
I have LYNX REGULATED WALL PACK and SERIAL CABLE.But I dont have BASIC ATOM or BASIC STAMP II.
PLease I need a proper and quick reply.Thanks in advance
Please tell me the quick list what I should have or buy in order to switch on the servo controller?
You appear to already have the purchased components required.
You may need to make your own cables to get the output of your instrumentation amplifiers and filters connected to the SSC-32 analog inputs. On page 2 of the SSC-32 users manual lynxmotion.com/images/data/ssc-32.pdf block 10 shows the location of the header with the analog inputs. The manual also explains how to connect power and configure the serial port baud rate if needed.
Pages 14 and 15 of the RIOS manual lynxmotion.com/images/data/rios02h.pdf illustrate enabling and using the analog inputs from the SSC-32. The balance of the manual does a fair job of walking you through the setup and operation of the software and arm.
Please note that processing EMG data and using it to do meaningful things with the arm will almost certainly require more capability than you can script with RIOS. Depending on the capabilities of your EMG analog interface and how well it filters the information, you should certainly be able to use RIOS to demonstrate proof of concept.
