AI+VSLAM visual technology innovation Rockchip helps the fourth generation of sweeping robot industry upgrade 523

The sweeping robot industry has developed rapidly in recent years. After three generations of development, including random, planned and navigation types, it still requires a lot of manual intervention. Pain points such as interaction methods, intelligent planning and hardware energy consumption cannot be solved. Rockchip has released four chip-level overall solutions based on the Linux system, which can help the industry upgrade and efficiently solve product pain points.

Among them, the flagship RK3399 chip adopts AI+VSLAM positioning and navigation technology, RV1108 and RK3326 support VSLAM image vision positioning and navigation technology, and RK3308 can realize mainstream laser navigation technology.

Rockchip released AI+VSLAM positioning and navigation technology based on RK3399 chip, which allows the navigation technology of sweeping robots to directly enter the fourth generation, truly realizing the AI ​​artificial intelligence of the industry, and perfectly integrating AI artificial intelligence with sweeping robots with image recognition, big data, deep learning, and intelligent algorithms.

RK3399, which adopts the fourth-generation navigation technology, is based on the CPU/GPU chip, visual recognition technology and AI algorithm, breaking the limitation of the original VSLAM technology's dependence on light conditions. It can not only be applied to complex indoor scenes such as weak light, weak texture, and strong light, but also can intelligently identify hundreds of indoor image objects, classify and record, visually measure distance and avoid obstacles, and plan the best cleaning path. In terms of human-computer dialogue and voice interaction, it supports multi-microphone array and far-field voice control. Sweeping and mopping can be completed through voice control, and it can support binocular vision algorithm.

RK3308 Features: Laser SLAM positioning and navigation technology

The RV1108 and RK3326 chip-level overall solutions released this time both have VSLAM image visual positioning and navigation technology. Although these two navigation technologies have been maturely applied, Rockchip's new solution has more advantages in hardware performance. In order to meet the R&D needs of different customers, the two types of chip solutions have made a distinction in the implementation of VSLAM algorithms:

RV1108 can support the implementation of VSLAM algorithm on DSP, has a built-in 8M ISP, and can support 3D cameras at the same time. For customers using VSLAM positioning and navigation technology, it can adapt to more complex usage scenarios; it supports MIPI CSI interface, and has a wider range of camera sensor modules to choose from.

RK3326 can support the technical implementation of VSLAM algorithm on the CPU/GPU side. The GPU of RK3326 adopts G31, which can support Full profile OpenCL2.0, and can quickly implement VSLAM algorithm on GPU. CPU+GPU work together to achieve better performance.

RK3308 can realize the laser navigation technology of mainstream sweeping robots and adopts 64-bit Cortex A35 architecture. Compared with similar solutions using 40nm Cortex A7, Rockchip solutions all use 28nm process for new processors with higher performance and lower power consumption, which can effectively solve the problem of chip heating, which is especially important for sweeping machines with built-in batteries.

[Summary of the five major technical advantages of Rockchip's fourth-generation sweeping robot]

In terms of technology, compared with traditional sweeping robot solutions, Rockchip's four solutions all have the following advantages:

【Innovative hardware elastic design】

Rockchip has many algorithm partners and ODM/OEM customers in the robot vacuum ecosystem, covering laser, VSLAM, AI and other fields, which can achieve rapid mass production. In response to the different product innovation needs of industry customers, Rockchip has also designed hardware flexibility for the four major robot vacuum solutions. In terms of peripheral materials, RK3399, RV1108, RK3326, and RK3308 can provide a wider support list for key components such as DDR/WIFI/BT/Camera/Nand Flash/EMMC. For partners, it will greatly enhance market competitiveness.

In the context of a rapidly growing industry, Rockchip, with its accumulation of artificial intelligence, image vision, and chip technologies, has released solutions that are extremely disruptive compared to traditional products. Combined with new Internet of Things (IoT), artificial intelligence and other technologies, the white goods market will have more opportunities for breakthroughs in limited changes.

Home appliances embedded with smart technology have not only become a market trend, but for the current intelligent transformation and upgrading of home appliances, it is a general trend to create artificial intelligence solutions for home appliances based on users' life scenarios and business scenarios. This will also be more in line with the characteristics of the era of artificial intelligence and the Internet of Things.
