Robotics

    Asimov's Three Robot laws:

    1)A robot may not harm a human or through an action allow a human to come to harm.

    2)A robot must always obey a human, unless it is in conflict with the 1st law.

    3)A robot must never let itself come to harm, unless it violates laws 1 and 2.

    SN754410 QUADRUPLE HALF-H DRIVER
    This Texas Instruments Chip can drive 4 1-Amp motors in one direction or two 1-Amp motors in two directions from TTL or CMOS inputs. This chip greatly simplifies the task of driving motors from small micros. It is a replacement for and an improvment over the Thompson L293D or Unitrode chip offering higher continuous current capacity (1.1-Amp versus 600 mA for theThompson). The chip is a 16-pin DIP.
