Key Design Challenges
The Hand Unit must coordinate multiple small actuators with high precision and responsiveness to replicate human dexterity. Integrating tactile, proximity, and pressure sensors within a compact form factor presents significant design constraints. Additionally, low latency wired communication is essential to maintain real-time control loops, while power management must optimize energy use without compromising performance.
