Intelligent food delivery robots have entered many restaurants. Especially during the epidemic, we should be screened out by food delivery robots in the Isolation ward. They provide meals to quarantined individuals in shelters, hospitals, isolation points, and isolation hotels, greatly reducing exposure to cross infection. They can be said to be important contributors to our fight against the epidemic.
- Autonomous Mobile technology
In order to realize free movement in the restaurant, the dining robot needs to be supported by autonomous Mobile technology. The autonomous positioning and navigation technology of robots solves the problems of positioning, map creation, and path planning (motion control) for food delivery robots; SLAM technology solves the problem of real-time positioning and map construction for catering robots running in unknown environments.
- Environmental Awareness Technology
To achieve an intelligent interactive experience, an intelligent food delivery robot must first have a certain level of environmental perception ability. In the environmental awareness technology, multi-sensor fusion is a major trend, including visual recognition, Structured light, millimeter wave radar, ultrasound, laser radar, etc.
- Speech recognition technology
The fields of speech recognition technology include signal processing, pattern recognition, Probability theory and Information theory, phonation mechanism and artificial intelligence, etc. The ultimate goal of robot speech recognition is to enable robots to understand people's spoken language, and then make correct action or language responses to the requirements or inquiries contained in the spoken language.
4、 Chassis technology
The chassis of the intelligent food delivery robot consists of a wheeled mobile platform, which can be seen as an independent wheeled mobile robot, including a transmission part, servo motor, charging battery, and control board card. The upper part of most catering robots is a humanoid robot body, and the lower part of the lower legs is a wheeled mobile robot platform.
5、 Intelligent chip technology
Intelligent chips are the brain of catering robots, including general-purpose chips and specialized chips. For robots, general-purpose chips and specialized chips each have their own strengths and responsibilities in the future, involving deep neural networks. GPU and FPGA in general-purpose chips are superior to traditional CPUs in solving complex calculations. In terms of operating systems, ROS and Android systems are currently the main ones.
6、 Multi machine scheduling technology
When multiple food delivery robots, such as those delivering dishes, serving guests, those with rails, and those without rails, serve together, it is necessary to use multi machine scheduling technology to coordinate and unify the various food delivery robots at key points, such as working at a unified point and charging them back and forth to complete the work. This is a key application in food delivery robots.
In the future, food delivery robots will gradually develop into a new trend in the catering industry, but there will also be more and more challenges and challenges to be solved. There is still a long way to go before food delivery robots can truly become "just needed" products.
