Wireless Charging System Extends Quadruped Robot, Unlocking New Application Scenarios

Across substations during industrial inspections and amid the rubble of post-earthquake rescue sites, quadruped robots are slipping into corners human cannot reach. Yet frequent charging cycles and energy resupply in harsh environments remain the bottleneck to large-scale deployment. Guangdong Titans Intelligent Power Co., Ltd. ("Titans" ) answers with the TTAC-WPT series wireless intelligent charger—a “safe, efficient, wireless” breakthrough that rewrites how quadruped robots operate.

Ⅰ. Quadrupeds in High-Risk Electrical Environments

Thanks to bionic kinematics, high-dynamic response, and modular payload bays, quadrupeds have become the go-to tool for emergency response, live-substation inspection, and security patrols.

① Emergency rescue: Fitted with thermal cameras, the robot penetrates collapsed structures, streaming vital-sign data in real time.

② Power-grid inspection: Autonomously navigating live HV yards and uneven terrain, it delivers full-coverage inspections while eliminating human exposure to arc-flash and missed-defect risks.

③ R&D education: As a testbed for motion-control and AI algorithms, it accelerates the convergence of robotics and electrical engineering curricula.

Ⅱ. Core Challengeof Conventional Charging

① Poor environmental compatibility: Outdoor dust and moisture accelerate connector oxidation and damage.

② Low mission continuity: Manual plug-in cycles waste manpower and interrupt task flow.

③ Safety hazards: Physical contacts can spark in explosive atmospheres common to petrochemical and utility sites.

Ⅲ. Titans: Wireless Power Transfer (WPT) Optimised for Quadrupeds

Titans' inductive system attacks these problems through three electrical-design advances:

①Contact-free power, low wear and safe: The transmitter and receiver are physically disconnected, eliminating contact wear and spark risks, and is compatible with dynamic obstacle avoidance and continuous operation scenarios for quadruped robots.

The IP65-rated design withstands extreme temperatures from-20°C to 55°C, ensuring stable operation in humid and dusty environments. It meets the requirements of overseas projects such as infrastructure in Southeast Asia and smart manufacturing in Europe.

②Wide positional freedom, flexible charging: Large-offset tolerance: The quadruped robot can automatically recharge without precise docking, allowing appropriate horizontal and vertical offsets, thereby improving the success rate of return to the target position.

A single ground pad time-shares 2–4 robots, cutting OPEX and matching high-density warehousing or logistics fleets.

Supports multiple robots sharing a charging base, reducing O&M costs and adapting to large-scale scenarios like warehousing and logistics.

③High-power fast charge, mission-level energy security: 500 W–3000W selectable output.It supports continuous robot operation, enabling multiple inspection rounds per day.Wide positional freedom, flexible docking.

Ⅳ. Outlook: Energy Revolution Enabling Human-robot Symbiosis

As AI, SLAM and torque-control algorithms mature, quadruped robots are migrating into social infrastructure. Titans leverages WPT as the pivot, expanding the broader ecological framework:

①Globalized service: Leveraging equipment operation and maintenance data from over 190 countries, we build a cloud-based management platform to deliver real-time fault alerts and energy optimization.

②Scenario expansion: Fromindustrial inspection to hospital drug-delivery corridors —turning the quadruped into a universal, always-charged electromechanical agent.

While the robot strides across rubble, Titans wireless link silently guards its energy lifeline. The revolution is not just a new charging method—it is a redefinition of electrical safety, mission uptime, and human-robot collaboration where danger is high and downtime.
