What are potential drawbacks or limitations of relying solely on neuromorphic hardware for robotic control?

While neuromorphic hardware offers significant advantages such as energy efficiency and low latency, there are some drawbacks to relying solely on this technology for robotic control. One limitation is the current complexity of programming spiking neural networks (SNNs) compared to traditional artificial neural networks (ANNs), which may require specialized expertise. Another challenge is the scalability of SNNs for handling complex tasks that require large-scale computations. Moreover, the lack of standardized tools and frameworks tailored specifically for neuromorphic hardware can hinder widespread adoption in robotic applications.

How might incorporating continuous learning capabilities enhance the performance of intelligent robots in practical applications?

Incorporating continuous learning capabilities into intelligent robots can significantly enhance their performance in practical applications. By enabling robots to adapt and improve over time based on new experiences and feedback from their environment, they can become more versatile and efficient at completing tasks. Continuous learning allows robots to refine their behaviors without requiring retraining from scratch each time conditions change or new challenges arise. This adaptive capability enhances robot autonomy, resilience to uncertainties, and overall effectiveness in dynamic real-world scenarios.
