I got an i-Box (v1) based robot for 100 baht. This robot is a PIC16C715 based device, with a dual motor driver, EEPROM serial memory and a comms IC, all mounted on a PCD a couple of inches square.
It has a number of variants, and brand names, such as:
hardware RoboCircle (3)(s)
essentially the same device.
It is quite difficult to locate any online information about the i-Box v.1, per se. Information on the i-Box III can be found online however,

Flight controllers, with built in sensors, don’t you just love them?

I was trying to save cash, whilst trying to
design a robot, and I was reluctant to purchase a full-on R/C transmitter, as these can be rather expensive.
After considering the PS2 controller options, which include using:
a custom PS2 receiver;
a standard generic Bluetooth USB adapter, and;
fooling the USB shield from wireless to wired (using the custom PS2 receiver).
For more information about these three options, see the
PS2 controller blog.
However, I then thought that I would see if I could use an XBox controller. Again there are multiple options available to the hacker:
Using a Microsoft wireless optical desktop receiver;
Using a generic Chinese clone;
Using the RF receiver from an XBox, and;
Some other hardware solution.
This blog will investigate each of these options.

Service please!, after watching a few more RC tutorials, I realised that I was severely lacking in knowledge on the power side of things.

Walking robots – Quadrapeds! Hexapods! Octobots! This is an expansion upon the
I, Robot blog. As my foray into the world of robots has expanded, so I have become more interested in the possibilities of a hexapod over the 4WD robot.

OK, so once I cleared my
initial confusion between stepper motors and servos, I ended up having to look into stepper motors – as well as servos, which are covered in the servo expedition. They is also another blog on the different topic of geared d.c motors, so you may wish to check that out as well.

Looking into servos (not to be
confused with stepper motors). I’ve always avoided motors and servos, ever since my HND days and beyond. I don’t know why, I guess I just liked to concentrate on transistors and discrete logic, but now I think it is time to overcome that fear.

I always fancied building a robot, but the cost was too high. The SparkFun RedBot is about £100.

However, as always the Chinese clones bring the price down considerably.
