Reconfigurable hardware devices that allow custom digital circuits to be implemented directly on the chip. In robotics and embedded systems, FPGAs are used to achieve low-latency and deterministic processing for tasks such as sensor data handling, real-time control, and hardware acceleration. Unlike CPUs and GPUs, which execute predefined instruction sets, FPGAs can be tailored to specific workloads, enabling precise timing behavior and energy efficiency. This makes them particularly suitable for safety-critical robotic applications and systems with strict real-time requirements. Although FPGA development typically requires specialized hardware design knowledge, their flexibility and performance advantages make them an important component in advanced robotic and automation systems.
