Top Robotics Physics Engines, Simulators and ROS2 Integration -

In robotics, physics engines and simulators serve different but complementary roles. A physics engine handles the mathematics of simulation such as computing forces, collisions, and the dynamics that make objects move and interact realistically. A simulator builds on these engines to provide a complete virtual testing environment, by adding sensors, 3D environments, visualization tools, and interfaces for communication with frameworks like ROS 2. In short, the physics engine provides the underlying math and realism, while the simulator delivers the interactive and visual layer needed for full robotics development and testing. ROS 2 (Robot Operating System 2) is an open-source middleware framework that enables communication between robot components such as sensors, […] Read More

OpenAI and NVIDIA partner to build 10 GW data centers -

NVIDIA and OpenAI have just entered into a partnership, to build 10 GW of AI data centers with NVIDIA GPUs. As each GW is deployed, NVDIA will invest gradually a total of $100 Billion, starting second half of 2026. The data centers will train OpenAIs next generation AI infrastructure. The detail of the strategic partnership will be finalized in the coming weeks.

What does Non-Linearity mean in Neural Networks? -

A neural network is made of layers, and layers are made of nodes (also called neurons or units). It is these nodes that process input data. First, each neuron that receives input. If this is the first layer, the input is raw data. If it is a higher order layer, the input comes from the layer below. The node applies weights to the inputs. Then adds a bias term. Then applies a nonlinear activation function (such as ReLU or sigmoid) and produces its outputs the resulting value to the next layer, which receives it as input. The keyword here is “nonlinear” because in real life things are rarely linear. Everything […] Read More

What Is Robot Description Format -

urdf robot description format

When designing robots, there is the need for a system in standardized format, to describe physical and kinematic properties of a robot. This is achieved by a robot description format. There are several commonly used formats including but not limited to URDF, SDF, MJCF. URDF (Unified Robot Description Format) is an XML based format which describes physical and kinematic properties of a robot for use in robotics software, and mainly in ROS (Robot Operating System), which is open source and the most widely used robot design software today. Let’s take a closer look at what URDF specifically does: Therefore it is a great tool in visualization of the robot and […] Read More
