The invention provides a multi-user human-computer interaction method based on millimeter waves. According to the multi-user human-computer interaction method, a millimeter-wave radar chip, a single micro transmitting antenna and a plurality of micro receiving antennas are embedded in a computer screen side, the transmitting antenna is used for transmitting a millimeter-wave signal in a specific range in front of a screen, and when encountering an obstacle, the millimeter-wave signal can be reflected to the receiving antennas. By calculating the time difference and frequency difference between signal transmitting and signal receiving, the distance and relative motion speed between the hands of a current user and the computer screen can be obtained. By comparing phase differences among all the receiving antennas, the arrival angle of each user is calculated, and in combination with the user distances, the spatial location of each user can be obtained. According to spatial location of each user, different users can be distinguished. Finally, distance and speed information of each user are enabled to be in one-to-one correspondence with a gesture of the user so that multi-user human-computer interaction based on the millimeter waves can be achieved. Compared with a technology based on optical stereoscopic imaging, the multi-user human-computer interaction method based on the millimeter waves is low in complexity and power consumption.

The invention provides a half-body robot and a remote control half-body robot, and belongs to the field of robots. Flexible movement of the head of the half-body robot is completed through a head rotating assembly and a head pitching assembly. Each arm is divided into a shoulder, a large arm, a small arm and a palm, and multiple transmission assemblies are arranged between every two adjacent parts to improve the degree of freedom. A trunk is provided with a trunk pitching assembly and a trunk rotating assembly, so that the movement of the trunk is more approximate to the biont, and the whole half-body robot has good flexibility and can complete various high-difficulty movements. The remote control half-body robot comprises a wireless transmitting device and the half-body robot. The movement of the half-body robot can be controlled through the wireless transmitting device.

The invention discloses a vibration table model test device capable of simulating interaction between a grouting anchor rod and a tunnel lining. The device comprises a tunnel lining template and a segment combined type grouting anchor rod, the tunnel lining template comprises a lining inner template, a lining outer template, a model bottom plate and a model top plate, and grouting anchor rod spaceorientation holes are formed in the lining inner template and the lining outer template such that specific preformed holes can be formed after the pouring and maintenance of the tunnel lining model are completed; the segment combined type grouting anchor rod is formed by splicing grouting anchor rod segment components, after the pouring and maintenance of the tunnel lining model is completed andthe tunnel lining model is placed in a model stratum, the anchor rod segment components are connected with the tunnel lining model through the specific preformed holes in the tunnel lining model, andfinally, an overall structure is formed. The standardized manufacturing of the tunnel lining model and the grouting anchor rod can be achieved, the flexible arrangement of the grouting anchor rod is achieved, different anchoring requirements are met, the two working states of drilling and grouting of the grouting anchor rod in the model stratum are simulated, and finally, the purpose of simulatingthe interaction of the grouting anchor rod and the model stratum under earthquake loads is achieved.
