Based on the vision of achieving smart unmanned reception in hotels, exhibition halls, office buildings, shopping malls and other commercial places, VOCA is designed as a lightweight reception robot to provide an efficient, low-cost and smart solution for reception. Equipped with highly sensitive sensors, VOCA can conduct real-time detection of the surroundings, automatic path planing and flexible obstacle avoidance, thereby gaining?higher environmental?adaptability. It can also accurately sense guests when they approach and actively receive them. Thanks to the powerful function of natural language processing (NLP), VOCA can execute guests' voice commands in multiple scenarios and perform voice interaction to meet various needs such as reception and consultation. The structural innovation minimizes the weight of VOCA. Its L-shaped body has a simple appearance, brimming with a sense of technology. Designed with duel display screens, namely the head interactive screen and front information screen, VOCA combines the functions of interaction and information promotion together. Moreover, the head interactive screen can automatically adjust to an appropriate angle to facilitate guests’ easy operation, serving them in a more active and humanized way. At the same time, VOCA is built in with massive-capacity rechargeable batteries, which can last up to 10 hours on a single charge. In low battery and standby mode, it can automatically return to the charging pile for charging. Accordingly, VOCA achieves round-the-clock service. The modular storage components at the back enables VOCA to transport various small objects. Users can freely customize the storage components according to their usage needs in different scenarios. Against the backdrop of regular epidemic prevention and control, contactless reception has become the development trend. VOCA effectively protects people from the risk of infection caused by direct contact during reception, and provides the service industry with a more safe way to reduce costs and increase efficiency.
