I would like to connect an angular sensor to drive the base motor on the owi 535 - just slide the sensor back-and-forth laterally
Do I need any software other than the Arduino ide?
Do you recommend an accel or gyro for the actual sensor located on the human-operator's arm.
Should I have a gyro/accel for both horizontal and vertical rotation of the shoulder-to-elbow linkage?
Does the arduino mega allow for future upgrade to wireless operation?
I am looking at a part from pololu http://www.pololu.com/catalog/product/2130 drv8833 that claims to
"deliver 1.2 A per channel continuously (2 A peak) to a pair of DC motors. With an operating voltage range from 2.7 to 10.8 V" it only costs $7 and would suffice for one motor rotating the base. Do you think it a better idea than 3) An Adafruit Motor Shield ($19.50) ? I will have to drive all 5 motors eventually - the instructable says the motor shield only drives 4 motors.
Is this an acceptable choice for the gyro?
1 L3GD20 3-axis gyro will give you the angular motion measurements: https://www.adafruit.com/products/1032
Is this an acceptable choice for the microcontroller - does it include future wireless compatibility?
can handle 3 to 4 input sensors (2 or 3 gyros and a pressure sensor to close gripper) and 5 motor control signals output?
1 Arduino Mega would be a good microcontroller to use. https://www.adafruit.com/products/191
Arduino Mega 2560 R3 (Atmega2560 - assembled)
do the XBee radios just plug in?
do I need a 3 Volt power supply battery pack to drive the motors?
what is the 'library support' you refer to for the motor driver drv8833?
Do you recommend any s/w,tutorial or reference sources?
