Shanghai, China, November 28, 2023 — ams OSRAM (SIX stock code: AMS ), a leading global provider of optical solutions, today announced its successful cooperation with ZLG to launch the AI-based EBO X companion robot in partnership with domestic robot supplier Enabot. This robot, supported by algorithmic technology provided by ZLG and equipped with TMF8821 sensors from ams OSRAM, features automatic obstacle avoidance, fall prevention, and assisted mapping capabilities.

With increasingly mature AI technology, companion robots are gradually entering domestic settings and becoming a significant factor in strengthening parent-child relationships. For a domestic robot, effective obstacle avoidance is a key prerequisite for achieving safe movement and intelligent caregiving. However, various challenges arise within household environments, including diverse layouts and a large number of dynamic obstacles. Consequently, robots often encounter challenges such as inaccurate perception and unclear path planning when in operation. To address these challenges, ams OSRAM and Guangzhou ZLG have engaged in a cooperation, aiming to empower Enabot to launch its new domestic companion robot EBO X that can provide better obstacle avoidance capabilities and mobility flexibility.

Each EBO X robot is equipped with two TMF8821 sensors from ams OSRAM, which are true direct Time-of-Flight (ToF) sensors and processing systems, and integrate a 940 nm Vertical Cavity Surface Emitting Laser (VCSEL), a high-sensitivity Single-Photon Avalanche Diode (SPAD) array, precision Time to Digital Converters (TDC), and a low-power microcontroller subsystem into a modular package. The size of this sensor is only 2.0 mm x 4.6 mm x 1.4 mm, making it highly suitable for applications where size constraints play a major role.

The TMF8821 sensor offers flexibility in its multi-zone configurations (3x3; 4x4; 3x6), allowing for an adjustable field of view with a maximum field of view of up to 63° diagonally. Alternatively, users can opt for a customized receiving area as required, thus enabling the adjustment of the size of each receiving area. Additionally, the sensor adopts the anti-interference algorithms designed to compensate for the effects of dirt and smudges on glass or acrylic covers. In terms of communication, TMF8821 provides distance values and confidence levels directly through I²C reporting – without the need for any external data processing! Furthermore, its power consumption is exceptionally low, with a standby current of just 13 µA. Additionally, the sensor incorporates advanced algorithms and wafer-level optical filters. This enables the sensor to deliver outstanding optical performance even in complex lighting conditions, such as intense sunlight.

In terms of the robot design, the ultra-compact size of the TMF8821 sensor ensures the robot's aesthetic appeal. Furthermore, ams OSRAM's dToF (direct Time-of-Flight) technology, with its excellent chromatic aberration resistance, enables the robot to confidently navigate over surfaces such as carpets and glass that may cause reflections. Compared to infrared-emission/receiver tube solutions, the range finding capability of TMF8821 from 10 to 5,000 mm allows the robot to detect height differences such as steps or tables from a greater distance and reminds the robot to brake in advance, thus effectively preventing falls. Moreover, the high-precision range finding capability and multi-zone detection of TMF8821 not only contribute to autonomous obstacle avoidance, but also facilitate the transmission of depth information to the main control unit. This enables the sensor to work in conjunction with cameras for V-SLAM mapping.

Richard Qin, Channel Manager at ams OSRAM, stated: "TMF8821 is one of the most outstanding ToF products in terms of performance at ams OSRAM, offering exceptional visual perception for applications such as robots. Thanks to its precise range finding capabilities across multiple zones and targets, TMF8821 enables robots to move without obstruction and navigate smoothly within their environment. Its compact size and ease of integration also provide customers with greater design flexibility."

Yang Liuyi, Product Manager at ZLG, commented: "We provided algorithmic support for the development of the TMF8821 sensor, optimizing its functionality to allow the more accurate acquisition of three-dimensional information and precise perception of environments. Thanks to the excellence of TMF8821, EBO X can more precisely identify the position, shape, and motion status of objects, thereby enhancing its action decisions and execution capabilities."

Mahe Yingsheng, CTO at Enabot, emphasized: "High-performance visual sensors are crucial for robots. TMF8821 from ams OSRAM perfectly aligns with our design requirements for EBO X. It can capture information in larger quantities and higher quality, significantly enhancing the environmental perception and allowing for the early detection and avoidance of potential obstacles, which makes it an ideal choice for domestic companion robots."
