A project log for YARRM - 7-DOF Low-Cost Robot Arm

Yet Another Robot aRM - where I develop a low-cost compliant robot arm with a 1meter reach, 1KG payload.

Need some input on what kind of controller I should use.

It will either be an arduino (because most people already have one) or the Raspberry Pi.

Servo driver will use the chip from the Adafruit 16-channel servo driver (i2c control).

I'm leaning towards the RPi just so that we can run some basic OpenCV code on it to set part localization (PickNPlace) usage).

After some more reading I have decided it will be driven by a Raspberry Pi + I2C servo driver. The arduino is just too limited (and expensive) and it wouldn't have been able to handle multiple arms, which the RPi can. (Plus, the RPi is already networked!).
