What Are The Technical Difficulties Of Robot Waiter?


Driven by the contactless concept and the market demand, it is increasingly to see robot waiters appear at different scenes include shopping malls, restaurants, hotels, hospitals, etc. However, it is not an easy thing to develop a robot waiter at the beginning. What are the technical difficulties of robot waiters?

To begin with, automatically optimal path planning and moving to the designated destination while carrying a certain weight of objects are the basic function of the robot waiter. Especially in places with crowded, flexible moving people and narrow activity space, the demand on robot waiter’s obstacle avoidance function and automatically positioning accuracy will be higher.

Given this, various external sensors will be added to empower robot waiters with fast and accurate position perception and automatic obstacle avoidance. For example, the 3D depth camera, laser radar, and ultrasonic sensor can all make the robot waiter support the obstacle avoidance function. It is worth mentioning that the laser radar can not only realize sound navigation and positioning due to the good directivity and high focus but also able to locate the surrounding objects (determine obstacle size, the distance between obstacles and robots, etc.). Thus, it is the evitable functional unit of the robot waiter.

In addition, the robot waiter will adopt SLAM+ path planning+ motion control solution in the autonomous positioning and navigation technology. The SLAM technology will help the robot waiter to achieve positioning and mapping construction. It enables the robot waiter to know its position in the unknown environment in real-time and draw the environment map synchronously, which is the premise for the robot waiter to realize path planning. After all, you need to know where the destination is and then be able to know where you're going.

Under such circumstances, Telpo robot waiter R55 adopts a 3D depth camera, laser, ultrasonic sensor, and pneumatic collision sensor to make sure strong three-dimensional position perception ability and accurately object distance measure. In addition, it also supports SLAM multi-sensor with laser, visual, and ultrasonic positioning& navigation solutions to achieve multi-route patrol mode. The three-layer tray with 20kg per tier enables 60 kg loading capacity in one run, while the removable plates give more flexibility to perform every task and assist contactless and unmanned delivery service.

Only with these technology units to enable obstacle avoidance and path planning could the robot waiter normally run. With the ability of plate sensing, obstacle avoidance, automatic charging, multi-point delivery, etc, the robot waiter delivers an efficient and contactless delivery service and funny experience, which is suitable for restaurants, hotels, office buildings, hospitals, and other scenes.
