Description

Technical Field

[0001] This utility model relates to the field of service robot technology, specifically a restaurant food delivery device. Background Technology

[0002] As people's living standards improve, various types of service robots are beginning to come into view. Popularizing service robots and promoting their integration into daily life is the most direct way for ordinary people to experience how technology contributes to improving their quality of life. It can also encourage people to learn more about and spontaneously engage with technology, thus providing convenience for their lives.

[0003] While the design of food delivery robot systems is relatively mature, the high cost of robot manufacturing and equipment maintenance remains a problem. Although humanoid food delivery robots can initially provide customers with a novel dining experience, their maintenance costs are high, and like ordinary humanoid robots, their appearance is not aesthetically pleasing. Although they can initially attract customers, the return rate is low, resulting in high costs and low returns for restaurants, which is not conducive to the sustainable operation of restaurants. Many small and medium-sized restaurants find it difficult to popularize food delivery robots, and the usage rate of food delivery robots is not high. Therefore, a restaurant food delivery device is needed to meet people's needs. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a restaurant food delivery device, including a food delivery robot body 1; in order to solve the problems of high maintenance costs of food delivery robots, and like ordinary humanoid robots, their appearance is not aesthetically pleasing. Although they can attract customers at first, the return rate is low, resulting in high restaurant costs and low returns, which is not conducive to the sustainable operation of the restaurant. Many small and medium-sized restaurants find it difficult to popularize food delivery robots, and the usage rate of food delivery robots is low. A fiber base plate 2 is installed on the food delivery robot body 1, and a column 21 is fixedly installed on the fiber base plate 2. A food delivery base plate 22 is fixedly installed on four columns 21. A power supply 23 and an Arduino control board 24 are installed on the fiber base plate 2, and a Bluetooth module 25 is integrated on the Arduino control board 24.

[0022] The fiber base plate 2 is equipped with a motor drive module 3, an obstacle avoidance module 4, a tracking module 5, and a voice module 6. The motor drive module 3, obstacle avoidance module 4, tracking module 5, and voice module 6 are electrically connected to the Arduino control board 24.

[0023] Because Arduino has a strong network communication protocol and wireless communication does not require establishing a TCP / IP1 protocol, using Bluetooth to transmit data can effectively reduce communication costs. Bluetooth data transmission has a short latency, good security, and can communicate without considering obstacles or communication direction within its communication range. The Bluetooth serial communication uses the HC-05 module to communicate with the open-source Bluetooth debugger APP on the mobile phone. The mobile APP remotely sends the table number to the main body of the food delivery robot 1 for remote control.

[0024] Example 2: As Figure 2 , 3 4. The motor drive module 3 is located on the fiber base plate 2. The motor drive module 3 adopts a three-wheel movement method, that is, it uses three wheels for movement. Two tires 34 are installed at the front of the cart, and two motors 33 are connected to these two tires 34 to drive the tires 34 to rotate. Then, a swivel wheel 35 is installed at the rear of the fiber base plate 2, aligned with the center of the two front tires 34, which can support the entire food delivery robot body 1 and can also rotate freely during movement. The three-wheel movement device is a commonly used structure in wheeled movement devices. It has a certain degree of stability, and compared with the ordinary four-wheel drive structure, turning does not require complex and precise calculations, which is simpler. It can make the food delivery robot body 1 move smoothly and make the food delivery robot body 1 more flexible when turning.

[0025] The L298N module 31 is selected to drive the two motors 33 at the front of the main body 1 of the food delivery robot. IN1 and IN2 of the L298N module 31 are connected to PIN7 and PIN8 of the Arduino control board 24 respectively to control the steering of the left wheel; IN3 and IN4 of the L298N module 31 are connected to PIN5 and PIN6 of the Arduino control board 24 to control the steering of the right wheel. The other features are the same as in Example 1.

[0026] Example 3: As Figure 2In order to avoid accidents and termination of delivery when encountering obstacles while delivering food, the main body 1 of the food delivery robot needs to detect the path ahead. An ultrasonic ranging module 41 and a voice module 6 are connected to the Arduino control board 24. When an obstacle is detected, the ultrasonic obstacle avoidance module 42 transmits the information back to the Arduino control board 24 via a pin. The Arduino control board 24 receives the data and processes it to achieve automatic obstacle avoidance. When encountering a pedestrian during obstacle avoidance, the robot stops and uses the voice module 6 to control the speaker 62 to prompt the customer to move aside. After waiting five seconds, it checks again to see if the customer has moved aside. If they have, the robot continues delivering food to the designated table. Upon arrival, the voice module 6 controls the speaker 62 to prompt the customer to collect their food. The remaining features are the same as in Example 1.

[0027] Example 4: Figure 2 and 3 When the food delivery robot 1 is moving to deliver food, in order to enable the food delivery robot 1 to follow the black line and achieve the purpose of line tracking, three infrared ranging sensors 51 are installed at the front end of the food delivery robot 1. The black line is located by sensing the intensity of the reflected light from each infrared ranging sensor 51. After the Arduino control board 24 determines the position of the food delivery robot 1, it executes the corresponding instructions to control the food delivery robot 1, so that the food delivery robot 1 can follow the line and reach the designated position during the movement. The other features are the same as in Embodiment 1.

[0028] The working principle is as follows: Commands are sent to the main body 1 of the food delivery robot via a mobile app. Upon receiving the command, the main body 1 moves to the designated location to wait for the customer to collect their food, then returns to its original position to await the next command. During its movement, the main body 1 locates the black line by sensing the intensity of reflected light from each infrared ranging sensor 51. After the Arduino control board 24 determines the position of the main body 1, it executes corresponding commands to control the main body 1 and guides it to the designated location. When an obstacle is detected, the ultrasonic obstacle avoidance module 42 transmits the information back to the Arduino control board 24 via a pin. The Arduino control board 24 receives and processes the data to achieve automatic obstacle avoidance. When encountering a pedestrian during obstacle avoidance, the robot stops and uses the voice module 6 to control the speaker 62 to prompt the customer to move aside. After waiting five seconds, it checks again to see if the customer has moved aside. If they have, it continues delivering the food to the designated table. Upon arrival, the voice module 6 controls the speaker 62 to prompt the customer to collect their food. After picking up their food, customers receive a blessing via voice module 6 and then return to their designated location to wait for the next delivery.
