Collaborative robots – or cobots – are becoming a mainstream technology. As they do, new varieties of cobot are being released, and new industries are being targeted. In this article, we take a look at a number of recent cobot trends.
In 2021, light duty cobots (with payloads of <10 kg), accounted for 83% of total shipments. Larger payload cobots (with payloads of >10 kg) accounted for 17%. This market share will grow slowly over time, particularly in the 10-12 kg range as they penetrate new scenarios where heavy lifting is involved such as the semiconductor industry, automotive and logistics.
Mainstream cobot manufacturers such as Universal Robots (UR) and Techman are leading vendors of models with these larger payloads. Additionally, because heavier cobots are more expensive, the market share increase in terms of revenue will show a more impressive increase, from 20% in 2021 to 25% by 2026 (Figure 1, below).
At the other end of the spectrum, very small collaborative robots are also gaining traction in the markets. Desktop collaborative robot arms with payloads of around 500g are seeing greater use in precision operations in industries such as electronics. Kawasaki, ABB and DOBOT are big players here.
The mobile collaborative robot, such as those produced by FANUC, where the collaborative arm is mounted on a mobile chassis, has seen fairly limited deployment across the industrial sector. In contrast, mobile robotics solutions have been deployed in some markets.
The main barriers to mobile manipulators have been technological – how to achieve integrated functionality across key parts of the robot – the chassis, the sensors, the robot arm, and the end-effectors. These challenges have had an impact on pricing. But technology has advanced, and we are beginning to see greater market acceptance of these machines.
The semiconductor industry – a sector which is a major investor in automated equipment – accounted for a large portion of mobile cobot deployments in 2021, the technology being applied in such scenarios as wafer manufacturing and packaging, as well as loading, unloading, and material handling. The second largest end-user of mobile cobots is the new energy sector, where applications include power inspection, data center inspection and the screen-printing process in the photovoltaic industry. Meanwhile, the third largest market is consumer electronics.
At Interact Analysis, we see huge potential in the application of mobile cobots on manufacturing production lines, chiefly because they bring the flexibility that modern manufacturing increasingly demands. However, mobile cobots can also be quickly deployed in non-manufacturing scenarios such as warehouses and automated supermarkets. Other niche applications being researched or piloted are education, medicine, file management and pharmacy management.
Interact Analysis anticipates that mobile cobots will make up more than 10% of the total cobot market by 2025, and that there will be over 11,000 units shipped in 2026. Whilst the technology will only take a minority share of the market, it will have a much higher year-on-year growth rate than its static counterpart.
Mobile cobot producers
In the initial stages of mobile collaborative robot production (mobile manipulators), machines were developed mainly by enterprises that had mobile chassis and cobot production capabilities, such as Omron and Siasun. Systems integrators also played an important role, purchasing mobile chassis and collaborative robot arms for customized assembly. A recent trend has been for mobile robot companies and collaborative robot vendors to cooperate in the development and production of mobile collaborative solutions.
At present, autonomous mobile robotics manufacturers dominate the mobile manipulator market with a near 70% share, with collaborative robot manufacturers also developing their own customized mobile solutions and taking a 10% slice of the market. Customer project focused integrators occupy the remainder, basing their offerings on their ability to tailor their solution to the needs of bespoke projects that they are already managing.
