A collection of links that I’ve been using recently for research.

Hitec HS-422 Servo. The servos I currently have; likely not suitable for use as actual leg servos due to lack of torque. Useful link as www.superdroidrobots.com has links to the spec sheet for the servo and a selection of different spec servos with corresponding prices. More useful to me than the actual Hitec website as that doesn’t list relative prices. Less useful to me than a UK supplier.
Servo power and speed. What the spec sheet figures mean. Also ServoCity has another useful list of comparative prices for various servos…
Society of Robots, USB Servo controller. This was vaguely useful when I was trying to work out how to build the electronics I needed; in the end it wasn’t really what I needed. Something that looks more useful to me are the mechanics tutorials…
Servo Magazine - looks interesting, perhaps.
TomboT - Tom Elnar’s website - useful robotics stuff.
Serial Wombat Servo Controller - something for ideas regarding how to control the servo controller.

Dick Cappel’s Project Pages - a useful collection of non-trivial AVR assembler examples.
AVR Tutorial - another useful assembly language tutorial.

The manual for the Phoenix Excel Program for creating servo position sequences for hexapod legs using inverse kinematics.
Some interesting stuff on mapping based on the use of a sonar sensor.
