Hey - just stumpled upon this again. It was the site on which I about 1.5 years ago entered because they sold wacky stuff.. And then I found this strange "chip" - "Picaxe.." and bought some of that stuff along with some more obscure items :D
They do have a lot of fun stuff, check it out, and hold on to your money ;)
Stackable prototying boards and microcontroller development boards. The AVR 28 pin board is suitable for ATmega8, ATmega168 or ATmega328 and with loads of prototyping space, it makes an ideal robotics platform.
This is an awesome competiton for anyone with a knowledge of engineering/mechanics. Came across this news and this competition this morning, and I feel like there are definitely some people here who could've come up with something good enough to win.
This is a blog post I wrote with my kids. We are just getting started with electronics and our goal is to build a robot to share here. We've done bristlebots and non-programmed types that bounce off obstacles and turn around and we really want to work towards something with programmed actions. We've got an Arduino Mega and a Raspberry PI we've tinkered with and plan to use in future builds, but to get us rolling I'm trying to step us slowly through the basics.
FingerTech Robotics is a design and manufacturing company that produces custom purpose-built electronics, mechanical parts, hardware, and accessories for hobby robotics. These products as well as complimentary robotic components are brought to the public through the FingerTech Robotics Online Store.
I find this quite interesting in regard of a FPGA controlled robot. Actually to build a simple FPGA we only need a parallel SRAM or EEPROM. We use the address lines as inputs and the data lines as output. Any combination of input logic states will be interpreted as an address, which the memory will look up and provide on the data outputs. By programming the memory (for example via DIP switches) with the state tables for the functions we want to compute, we can create a very complex behaviour of the robot, without using any micro controller.
Neat example of controlling a servo with Arduino. Using the servo library, it's not that complicated, plus the example also shows how to interface with Processing, allowing you to control the servo with your mouse.
