“…In the domain of (neuro)robotics [79], viable tools have emerged over the past years [115,366,226], offering improved physics engines for simulating real-world robotic systems and some of the task environments in which they would operate. With respect to neuromorphic substrates, simulators of neuromorphic chips [196,217] and emulator kits, e.g., the RISP neuro-processor [282,281,130], have recently emerged; offering an alternative to expensive, non-mainstream hardware. However, while digital emulation might prove to be an invaluable solution, even serving as a force behind the rapid prototyping of early mortal computers, there is always a prescient gap between the fidelity and realism of a particular simulation and the real-world niche that it attempts to emulate, i.e., the "sim2real" problem [173].…”
