What type of machine is designed to execute one or more tasks repeatedly, with speed and precision?

The type of machine designed to execute one or more tasks repeatedly, with speed and precision, is best described as a robot. Robots are specifically engineered for repetitive tasks, often in manufacturing and automation settings, where they can perform complex sequences of operations reliably and accurately. They are equipped with sensors, actuators, and control systems that allow them to adapt to different tasks while maintaining efficiency.

In contrast, manipulators refer more to systems that physically interact with objects, such as robotic arms, without necessarily embodying the full capabilities of a robot. An assembler typically refers to a process or device that specifically puts components together but does not emphasize the precision and speed of executing a variety of consecutive tasks. An automaton is a broader term that can refer to a self-operating machine but is often used in contexts that imply a simplistic or predetermined behavior, rather than the sophisticated, adaptive nature of robots designed for repeated tasks.
