Shenzhen-based industrial automation startup DP Robot has secured tens of millions of yuan (estimated US$3 million) in seed funding, with Plum Ventures as the sole investor.

The company specializes in automating screw-tightening processes across manufacturing lines, offering four- and six-axis robots, proprietary torque tools, and integrated workstations. Its systems have already been adopted by major clients including BYD, Ecovacs, and Sunwoda.

DP Robot aims to tackle the inefficiencies of manual fastening and the limitations of conventional XYZ gantry systems. The need for greater precision and shorter product cycles—particularly in the EV and smart appliance sectors—has created demand for more flexible, intelligent solutions.

The startup’s SCARA robots, paired with in-house smart tools, manage screws ranging from M0.8 to M10. This setup improves efficiency by 15% to 30%. Sensors monitor torque, angle, and pressure with high precision. Meanwhile, the software is designed for modular and user-friendly operation with quick setup times.

To scale distribution, DP Robot has built a network of nearly 100 channel partners. It plans to further upgrade its platform through modular hardware updates, enhanced data interfaces, and AI-driven capabilities for complex assembly scenarios.

🧠 Food for thought

1️⃣ Screw-tightening automation represents the next phase in centuries of fastening innovation

Automated fastening systems like DP Robot’s follow a long trajectory of technological advancement that dates back to the first century CE, when wooden screws were used for wine and olive oil presses 1.

The manufacturing of metal screws took a major leap in the late 18th century with Jesse Ramsden’s invention of the first effective screw-cutting lathe in 1770, enabling mass production of consistent threaded fasteners 1.

A pivotal innovation came in the 1930s when Henry Phillips designed the cross-head screw specifically to improve automotive assembly line efficiency, with Cadillac being the first to adopt this technology that prevented driver slippage during high-torque applications 2.

Early automation efforts advanced in the 1950s, exemplified by Toyota’s first transfer machine (TR1) in 1956, which could continuously process screw holes across eight stations, showing how fastening operations were central to manufacturing automation from its earliest days 3.

DP Robot’s AI-driven systems represent the latest evolution in this progression, addressing persistent challenges in precision and consistency that have plagued fastening operations throughout manufacturing history.

2️⃣ The deceptive complexity of fastening creates a significant automation opportunity

While seemingly simple, screw tightening represents one of manufacturing’s most deceptively complex processes, with fastening often being the first critical step in assembly that directly impacts product quality and reliability 4.

Manual tightening methods lead to inconsistency, quality issues, and workplace injuries, explaining why manufacturers are increasingly seeking automated solutions for this fundamental process 4.
