Once the servo controller code was feature complete I switched to looking at the hardware side of things and thinking about the next stage, the servo sequencing.
From a hardware point of view I had several things to work on.

I decided to treat myself to an early christmas present and bought a 60W temperature controlled soldering station (a ZD-916 which I got from Maplin). All I can say is WOW. Suddenly I can solder neatly rather than making a smeary mess.

For those of you interested in the kind of thing that this blog is about you might also find ChipHacker.com useful. It’s a ‘stackoverflow’ for embedded programming and electronics people. Hopefully it will become a useful resource!

I now have an easy to extend PWM servo controller and the next job on my list of things to do is extend it so that it supports the functionality that I feel I need for correct control of my hexapod’s legs.

Here are some links that may help once I move onto fabricating the various pieces required to build the hexapod’s body.
This is a simple 4 legged walking robot that was machined from an A4 piece of 4mm ply wood.

Servos and robotics 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.

My package from Cool Components arrived this morning. My choice of prototyping equipment was quickly validated when I plugged together the Arduino and the Pololu servo controller board, plugged in the servos and servo power supply, connected the lot to the pc via a usb cable and had three servos twitching back and forth under the control of the Arduino is no time.

I saw these Dynamixel DX servos mentioned on Trossen Robotics this morning, see here. They’re interesting because they have a richer interface than the normal hobby servos that I’ve been looking at and they provide a multidrop RS485 interface so that you can chain multiple servos together and control them individually via a single line.

Hi, my name is Len Holgate and this is a blog about my new project to design and build a hexapod robot; a mechanical vehicle that walks on six legs…
By day I design and build high performance TCP and UDP servers for the Windows platform, my C++ technical blog is here: www.
It seems that there’s a ‘known issue’ with DevPartner studio’s instrumentation and VS2008. Apparently the compiler architecture changed somewhat between VS2005 and VS2008 and sometimes the instrumentation is incorrect which is the cause of my ‘strange crashes’ with DevPartner 9.0. There’s no patch available at this time…
