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 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 […]
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 […]
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 […]
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 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 […]
The purpose of a robotic gripper is to effectively manipulate and grasp objects. First of all, the system for gripping must be chosen. Such as two or more finger grippers, parallel jaw grippers, suction grippers and other types. Some grippers are designed for only specific types of objects, which makes the design easier. Let’s list […]
When building bipedal robots (robots that walk on 2 legs), ensuring stability is a primary objective. The following strategies are among the most important: 1- First of all, before even considering the rest, we need to make the physical shape and mass distribution as good as possible for a proper, stable stance. This simply means-the […]
Co-bot stands for “collaborative robots”. These robots are designed to work alongside humans, by performing repetitive or heavy tasks, which would greatly ease the burden on the human worker while he or she can focus on tasks that require higher skills. A critical item for making this possible is to implement certain safety mechanisms on […]
To navigate its environment, a robot must be either remote controlled, preprogrammed in a known unchanging environment, or it must be able to do this autonomously. To be able to navigate autonomously a robot must be able to not only continuously model and update its environment, which can be static and dynamic, but also be […]
