ZoneCharge offers a dual-layout wireless charging solution for humanoid robots: sole-embedded or back-mounted. The sole version integrates the receiver in the feet and transmitter in the floor; it auto-charges with ~5cm distance and misalignment tolerance, lowers the center of gravity, supports opportunistic top-ups, and eliminates sparks—ideal for harsh environments. The back version places the receiver near the center of mass, with wall/pillar-mounted transmitter; it preserves dynamics, frees limbs for service robots, and saves floor space for homes, showrooms, and offices. Both options cover all scenarios.
