Thouzer Collaborative Transport Robot

Doog Inc. is a robotics company headquartered in Tsukuba, Japan, with a subsidiary office in Singapore. It builds small collaborative transport robots that reduce manual carrying work in factories, warehouses and maintenance sites.

The Thouzer line (Mini, Standard, Giant and Giant4M models) offers three driving modes: auto-follow behind a person, cart or another Thouzer; line trace along retroreflective floor tape; and memory trace, where the robot learns a route after a worker walks it once, without a PC or Wi-Fi. Laser sensors detect obstacles, and digital I/O and communication APIs allow connection to external systems.

• Auto-follow: follows people, carts and other Thouzer units while carrying loads.
• Line trace: runs along retroreflective tape, stops and sounds an alarm for obstacles.
• Memory trace: learns a route after one manual walk without a PC or Wi-Fi.
• Model range: Mini, Standard, Giant and Giant4M with swappable cargo beds and towing options.
• System integration: digital I/O and communication APIs for external equipment.
• Outdoor use: operates on slopes, uneven ground and in light rain.

Moving parts and tools between process stations in electronics and mechanical factories. Carrying goods between warehouse zones and buildings in logistics centers. Automated carrying of components inside maintenance depots, as in the JR Central rolling stock depot deployment.

Reduces the number of staff dedicated to transport. Works in narrow aisles (Standard handles 80 cm straight aisles), on slopes and between buildings including outdoors. Memory trace needs no initial setup or route-change cost, so layouts can change often. Suits small pilots and rented sites where fixed conveyors are impractical.

Labor shortages and rising wage costs in manufacturing and logistics push factories in Japan and Southeast Asia to automate in-plant transport without rebuilding layouts. Lightweight follow-me and route-learning robots offer a lower-barrier alternative to conveyors and full AMR fleets for SMEs, including those in Vietnam.

Headquartered in Tsukuba, Ibaraki, Japan, with Doog International Pte. Ltd. in Singapore. Received a 2020 Japan Robot Society practical technology award and a Robot Grand Prix SME/venture award. Five international patent applications listed for Thouzer.
