hello engineers.Iam currently doing a project on robot arm that involves five degree of freedom.actually iam using stepper motor as actuator..so please suggest me suitable microcontroller for my project..torque capacity=50 to 100..this depends on the pay load of the end effector.so suggestions r welcomed..

hey simple use any mc..like atmega 8,16 or 32....or of atmel series...for moving arm at different degrees u need to program it ..n as far as touque is consider..i guess it totally depends upon your actuator capacity..i guess..ya

anytime buddy..most welcome

ya sure..for basics of microcontroller...read
1. the 8051 microcontroller, by Ayala Kenneth
2.TMH Microcontroller , by A. V. Deshmukh
3.microcontroller by, V. Udayashankara and M. S. Mallikarjunaswamy

2nd one is the nice book..though the other 2 are also good...but i think for begineer 2nd 1 will be helpful n good.i.e mc by AV Deshmukh..i hav the link for this ebook [<a href="https://books.google.co.in/books?id=5PDx2Q9Ea_YC&lpg=PR13&ots=uAssMaRvkA&dq=TMH%20Microcontroller%20%2C%20by%20A.%20V.%20Deshmukh&pg=PP1#v=onepage&q=&f=false" target="_blank" rel="nofollow noopener noreferrer">Microcontrollers: Theory and Applications - Ajay V Deshmukh - Google Books</a><a href="https://books.google.co.in/books?id=5PDx2Q9Ea_YC&lpg=PR13&ots=uAssMaRvkA&dq=TMH%20Microcontroller%20%2C%20by%20A.%20V.%20Deshmukh&pg=PA1#v=onepage&q=&f=false" target="_blank" rel="nofollow noopener noreferrer">Microcontrollers: Theory and Applications - Ajay V Deshmukh - Google Books</a><a href="https://books.google.co.in/books?id=5PDx2Q9Ea_YC&lpg=PR13&ots=uAssMaRvkA&dq=TMH%20Microcontroller%20%2C%20by%20A.%20V.%20Deshmukh&pg=PA1#v=onepage&q=&f=false" target="_blank" rel="nofollow noopener noreferrer">Microcontrollers: Theory and Applications - Ajay V Deshmukh - Google Books</a>

try..this..

At Student level ATMEGA16 is best and torque is depend on your motor not on controller i think so.

Virtually any microcontroller should be able to handle this project. If you have a special requirement, like lots of ADC or DAC, or something, you'll have to specify.

Microchip and Atmel both have a wide lineup that will allow you to switch easily if your chosen chip doesn't work for some reason.

TI MSP430 has good analog and LCD support, neither of which you need, but it is still a good platform overall, just with fewer devices.

Renesas is popular in Europe but not in North America - their peripheral sets tend to be weird, and it's not as easy to move around from chip to chip. Support may be good in your area, or may not be.

If you'd like to go for a more sophisticated solution right off the top, try the ARM7 cores from Atmel and NXP (SAM7S and LPC2000 families). These have a lot of great stuff on them. Power consumption and analog support is not quite as good as their 16-bit cousins, but it's damn close, and I don't think you care anyway. ARM7s cost around $3 $USD in any kind of decent quantity.

Get a flash chip, stay away from one-time programmable (OTP) devices, and devices that need external memory. Also, I'd stay pretty basic unless you need special stuff for operating your arm - you don't need a Blackfin or Cortex-M3 device for this!

Also look at how much it costs for the development kits. Most 16-bit uC have $99 programming kits available now, but perhaps not all.
