1. An aluminium two-wheeled robot (ALBot) for teaching Phil Culverhouse

2. ALBot v1 Robot motor & wheel assembly Atmel microcontroller Interface PCB Field Programmable Gate Array (FPGA)

3. Atmel controller & robot Programme in C –Use AVRstudio and JTAG interface –PID controller available embedded Robot can operate from PSU or battery Fast – up to 2metres per second! –Teaching version of Mirosot competition robot footballer

4. ALbot sensors Sensors –Infra-red chat (front facing) –Infra-red Line detect (bottom) –VGA colour camera

5. FPGA Altera FPGA EP2C8T144 – 200MHz programmable hardware Quartus development tool Design in logic schematic and/or VHDL (Very high speed IC Hardware Description Language)
