Pipe mapping and repairing robot of CMU

Pipe mapping and repairing robot of CMU

Carnegie Mellon University Robotics Institute Researchers have developed a robot that can crawl inside natural gas pipelines to map them, while also detecting and repairing their leaks when necessary. The research project, which is near completion, was sponsored by the U.S. Department of Energy (DOE) through the Advanced Research Projects Agency-Energy (ARPA-E) and its Rapid […]

Electrical Circuit

An electrical circuit is a loop which provides a path for electric current (electric charge) to flow. This loop must be closed. In other words, the current must be able to flow from positive to negative terminals otherwise the flow will not take place. The charge is made possible by a source such as a […]

Conductors, Insulators, Semiconductors

Conductors: Conductors are the materials that easily allow flow of electric current upon application of voltage, such as copper. Conductivity is the measure of how easily current will flow through that material and shown by the symbol σ (sigma). Its unit is Siemens / meter (S/m) but usually milliSiemens / meter is used. It is […]

Sensors and Transducers

Sensors and transducers can sometimes be confused because they both react to some change in their environment but they are not the same thing. SENSOR A sensor is a component in an electronic system that can detect (sense) various types of changes in the physical environment and as a result, communicate these to the bigger […]

Analog vs. Digital Electronics

We can look at electronics in two different ways, both of which have different uses, which are analog vs. digital electronics. In short, analog electronics deals with continuous, smoothly varying signals, and digital electronics is about handling discrete signals (which are either on or off or in other words, 1 or 0). ANALOG ELECTRONİCS In […]

Robot Actuation Systems

Robot Actuation Systems

Actuation in robotics means the systems that enable physical movement. The most common ways of actuation are by electric motors, pneumatic and hydraulic systems, which we will introduce below. But note that there are other actuation systems as well, achieved by shape memory alloys, piezoelectric action, electromagnetism, movement achieved through thermal properties of materials and […]

Musk’s humanoid Optimus shows progress

Elon Musk has just tweeted about his humanoid robot Optimus. It seems that the android is now capable of locating his own limbs in space and in connection with this, can learn tasks, even in a changing environment. The video in Musk’s tweet shows that the android can sort cubes based on their colors by […]

Optimizing mobile robot power efficiency

Optimizing mobile robot power efficiency The basic physical body of the robot should be understood and optimized first. Robot should be as lightweight as possible, unless high mass (for weight or inertia) is needed for a specific reason. Friction between moving parts should be minimized except for the parts that need a certain amount of […]
