The Difference Between Stepper Motors, Servos, and RC Servos
Stepper motors:
A stepper motor’s shaft has permanet magnets attached to it. Around the body of the motor is a series of coils that create a magnetic field that interacts with the permanet magnets. When these coils are turned on and off the magnetic field causes the rotor to move. As the coils [...]
Photo Detectors
Photosensors or photodetectors are sensors of light or other electromagnetic energy. There are several varieties:
Most optical detectors are quantum devices in which an individual photon produces a discrete effect.
* Chemical detectors, such as photographic plates, in which a silver halide molecule is split into an atom of metallic silver and a halogen atom. The photographic [...]
WowWee Robosapien Version 2 Humanoid Robot
Robosapien Version 2 is the next generation of Robosapien technology and personality from Wowwee. This new member of the robotic family comes with more advanced dynamic motion, interactive sensors, new program functions, speech capability, and a personality all his own. It’s clear from the start that he enjoys bowling, dancing, and having conversations.
Movement
RobosapienV2 is able [...]
Voltage Comparator
In electronics, a comparator is a device which compares two voltages or currents and switches its output to indicate which is larger. More generally, the term is also used to refer to a device that compares two items of data. Output voltage will “switch” whenever the input voltage (at the inverting input) reaches the reference [...]

Whole New Ball Game As A Robot Makes I-Contact
ASIMO, the world’s most advanced humanoid robot, can’t drive his own car yet, but he is helping manufacturers make vehicles safer.
Twenty-one years of technology have allowed the all-seeing, all-hearing and sometimes-dancing Asimo to evolve from a disembodied set of legs that took up to 20 seconds to pace a single step into a robot that [...]
WowWee Roboreptile Robotic Reptile
Wowwee’s Roboreptile is an often startling robotic toy that, once you get the hang of its wonky controls, is actually pretty fun. Like other Wowwee robots, there’s a preprogrammed animation that goes off when it is first powered up. It’s impressive: growling, snapping jaws and a whipping tail. In short, Roboreptile looks like something out [...]
Future Of Consumer Robotics May Rest On Toy Dinosaur
SAN FRANCISCO (Dow Jones) — A small green and tan dinosaur slowly wandered across the table in an airy Emeryville, Calif., office space. As it plodded to the end of the table, one plastic hoof started to step off the ledge and instead it felt thin air. It slowly backed up and murmured a little [...]
