What do you get when you throw a little USB, some SPI, and a PmodRF2 into a MiWi stew? If you cook up all of those ingredients in a Cerebot 32MX7 pot, you will end up with a mechanically inclined 32-bit RF-capable robotic controller. This month, Fred shows you how to use various Digilent Pmods and the Microchip MiWi stack to establish an RF data link between a pair of Digilent Cerebot 32MX7s.
Joe takes us on his journey in developing a laser range finder, from beginning concepts to finished product.
This last installment will show you how to add infrared remote control, line following sensors, a compass, and an infrared range sensor.
For this last part, a more complex and useful digital design using the Basys2 FPGA trainer will be demonstrated.
By moving up to a miniature computer to operate your Beginner Bot, you’ll be able to modify its action and behavior just by rewriting a few lines of code.
