01 / INDUSTRIAL APPLICATIONS
Robot charging without exposed power contacts
Contact wear, oil, water, dust and alignment problems can interrupt charging and add maintenance work. We design contactless power connections around the robot’s docking process and operating environment.
Docking and alignment
Design coils, positioning tolerance and controls around the robot’s docking movement.
Charging between tasks
Coordinate power transfer with autonomous docking and charging opportunities in the robot’s work cycle.
Power, alignment tolerance and environmental protection are specified for each application.
Industrial applications
Industrial mobile robots
Charging interfaces and power integration for automated guided vehicles (AGVs) and autonomous mobile robots (AMRs).
Outdoor autonomous delivery
Docking and charging connections for outdoor delivery equipment, with alignment and environmental protection designed for the application.
Energy and industrial inspection
Power connections for inspection equipment in oil and gas, power and mining applications, where oil, water, dust and vibration affect the design.
APPLICATIONS & DEMONSTRATIONS
Robot and desktop applications
Wireless power in a quadruped robot, and wireless charging with screen sharing in an iPad stand.
30 W IPAD KIT
Wireless charging and screen sharing for iPad
The magnetic stand charges the iPad while mirroring its screen on an external display. Power and data travel wirelessly between the iPad and the stand; an HDMI cable connects the stand to the display.
02 / CONNECTION TECHNOLOGY
How the wireless connection works
Power passes between the transmitter and receiver through magnetic coupling. We design the coils, power circuits and controls to suit the equipment and its docking arrangement.
Magnetic resonant power transfer
Magnetic resonant coupling transfers power between the transmitter and receiver without exposed electrical contacts. We design the coils, magnetic circuit and power electronics for the required power and operating distance.
Docking and alignment
We design coil layouts, magnetic components, shielding and controls together, and assess positional offsets and equipment interfaces for the intended docking process.
Programmable power output
Digital controls set output voltage and current to suit the equipment. We coordinate these controls with the equipment’s operating states and system interfaces.
