Overvoltage and undervoltage protection circuit diagram | High and low voltage protection circuit diagram Using LM358

Main High/Low Voltage Cut-off Circuit Using Dual Op amp Lm358

Voltage fluctuations and power cuts adversely affect various electrical appliances such as Tv, music system, refrigerator, etc. Here is a simple and inexpensive circuit using opamp Lm358 to disconnect the equipment during high and low voltage. We can also use LM324 to design this circuit by using only the two …

Autonomous system improves environmental sampling at sea

An autonomous robotic system invented by researchers at MIT and the Woods Hole Oceanographic Institution (WHOI) efficiently sniffs out the most scientifically interesting — but hard-to-find — sampling spots in vast, unexplored waters. Environmental scientists are often interested in gathering samples at the most interesting locations, or “maxima,” in an environment. …

Self-transforming robot blocks jump, spin, flip, and identify each other

Swarms of simple, interacting robots have the potential to unlock stealthy abilities for accomplishing complex tasks. Getting these robots to achieve a true hive-like mind of coordination, though, has proved to be a hurdle. In an effort to change this, a team from MIT’s Computer Science and Artificial Intelligence Laboratory …

System prevents speedy drones from crashing in unfamiliar areas

Autonomous drones are cautious when navigating the unknown. They creep forward, frequently mapping unfamiliar areas before proceeding lest they crash into undetected objects. But this slowdown isn’t ideal for drones carrying out time-sensitive tasks, such as flying search-and-rescue missions through dense forests.   Now MIT researchers have developed a trajectory-planning …

Pushy robots learn the fundamentals of object manipulation

MIT researchers have compiled a dataset that captures the detailed behavior of a robotic system physically pushing hundreds of different objects. Using the dataset — the largest and most diverse of its kind — researchers can train robots to “learn” pushing dynamics that are fundamental to many complex object-manipulation tasks, …
