BEAM Robotics

BEAM (Biology Electronics Aesthetics and Mechanics) Robotics , it is an approach to robotics using simple analog circuits rather than using micro-processors or micro-controllers. This concept uses a type of circuit configuration which mainly consists of a neural network referred as "Nervous Net" or "Nv Net" whose element are none other than artificial neurons.

Why??
Reduce the cost and complexity of the design. It takes less time to build a Beam-Robot rather than designing traditional machines, also the size of Beam Robots are smaller than traditional robots.

Nv Neuron ???
Artificial neurons are made of a resistor, capacitor and a NOT gate.

ATmega32's Internal EEPROM


The EEPROM is an area of read/write memory that is non-volatile i.e., the stored data is not lost even if you power off the device.

The ATmega32 has a inbuilt EEPROM in it . Before starting to learn about using the internal EEPROM, let's get to know about the risk's that involve in using a Internal EEPROM.

  1. Internal EEPROM might get corrupted while the power is being switched off.
  2. Supply voltages are likely to rise or fall slowly during power up or down, this causes the device to operate at a voltage lower than the specified minimums voltage for the clock frequency used. This might lead to an unintentional write of the EEPROM.
