Introduction
Simulation is a critical step in robotics development. Before deploying robots in the real world, engineers test designs, algorithms, and controls virtually to save time, resources, and avoid damage. Two of the most widely used robotics simulation platforms are Gazebo and V-REP (now called CoppeliaSim).
At CuriosityTech.in, learners can explore simulation tutorials that guide beginners from basic virtual robot modeling to complex autonomous system testing, ensuring that theoretical learning seamlessly transitions into practical implementation.
