Dog-Shaped Robot and Drone Collaboration in New Wireless Power Transfer Model, Demonstrating the Forefront of Microwave Power Transfer – Exhibiting at Wireless Japan × Wireless Technology Park!

B & Plus Co., Ltd. will exhibit at Wireless Japan × Wireless Technology Park 2026, to be held at Tokyo Big Sight from Wednesday, May 27 to Friday, May 29, 2026.

We plan to exhibit demo machines for all three types of wireless power transfer methods: electromagnetic induction, electric field coupling, and microwave. You can experience their potential through automated demonstrations combining drone charging and robots.

### About Wireless Japan × Wireless Technology Park 2026

Wireless Japan × Wireless Technology Park (WTP) is one of the largest specialized exhibitions in Japan for wireless communication technology. It brings together cutting-edge wireless technologies and solutions, disseminating information on business creation and research and development. It is recommended not only for engineers in the communication field but also for those looking for solutions to their company's challenges or hints for new businesses.

### Highlights of the B & Plus Booth

At this exhibition, we plan to showcase demo machines for all three types of wireless power transfer methods: "electromagnetic induction," "electric field coupling," and "microwave." A comparative exhibition using actual machines is rare in Japan, allowing you to confirm the differences between each method on the spot. If you have questions like "I don't know which method is suitable for my company's application" or "I want to know how much it can actually be used," please come and experience the actual machines at our booth.

#### [1] Rail Robot Prototype Set (Electromagnetic Induction Method)

This system uses a robot that runs on rails to easily automate verification and evaluation.

It combines Wi-Fi communication, RFID control, and wireless charging, and can be customized with additional cameras and sensors. Ideal for PoC and demo applications! You can experience automation with robots moving on rails.

#### [2] Dog-Shaped Robot + Drone Charging (Electromagnetic Induction Method)

This system involves a dog-shaped robot equipped with a drone station, allowing drones to wirelessly charge upon landing.

The dog-shaped robot transports the drone to the takeoff point, solving battery charging issues in places inaccessible to humans.

Application examples: routine equipment inspection, security patrols, disaster relief, etc.

#### [3] Linear Track Power Transfer Demo Machine (Electric Field Coupling Method)

We will exhibit a linear track power transfer demo machine that can be constructed simply by attaching electric field coupling electrodes using 0.1mm thick aluminum tape. With easy installation that only requires cutting and pasting with scissors, the area, shape, and arrangement can be freely designed, and it can adapt to curved surfaces and various materials other than metal, achieving high flexibility.

#### [4] Long-Distance Microwave Power Transfer Experimental Unit (Microwave Method)

We plan to demonstrate long-distance microwave wireless power transfer. A circularly polarized antenna enables wireless power transfer to rotating and moving devices from several meters away. The experimental unit, scheduled for release within the year, features a separated configuration of a thin antenna and a transmitter, achieving high layout freedom for installation in confined spaces. Furthermore, it adopts a dedicated rectification device, supporting a maximum DC output of 4W (varies with distance).
