From December 12th to 22nd, “InnoTech Expo 2022” was held at the Hong Kong International Convention and Exhibition Center.Led by Professor Gao Feng of the School of Mechanical and Power Engineering of Shanghai Jiaotong University, the State Key Laboratory of Mechanical Systems and Vibration of Shanghai Jiaotong University, the Institute of artificial intelligence and Shanghai Intelligent Manufacturing Functional Platform Co., Ltd. jointly developed three types of skis, curling and blind guides. footrobotfeatured in this exhibition.
It is reported that when the ski robot was designed, the Robot was tested by manual remote control and autonomous planning. First, the robot’s height, body pitch angle, center of gravity position, snowboard angle, front and rear position, and left and right leg height were tested on the ski machine. Take control, complete speed and steering control tests. The data shows that the maximum speed of manual remote control stable steering and taxiing can reach 3.2m/s, the maximum speed of self-planned uniform straight line taxiing can reach 5.17m/s, and the maximum speed of stable steering and taxiing can reach 2.45m/s.
The control of the limbs of the curling hexapod robot is also complicated and requires a higher degree of cooperation: in the process of throwing the pot, the front legs of the robot are transformed into “human hands”, and it is necessary to complete the holding and rotating curling. The knees of the middle legs Combined with the elbow joints of the front legs to form a four-point contact with the ice surface, forming the function of human support legs; the rear legs step on the kicker to realize the function of accelerating gliding. In addition, the front legs can also throw the curling stone a second time during the gliding process of the robot, controlling the direction, speed and angular velocity of curling to achieve precise throwing and hitting functions. The data shows that the maximum linear velocity and angular velocity of curling can reach 4m/s and 30rpm respectively.
The blind-guiding robot has extremely high requirements on stability and recognition ability, so a variety of visual and force senses have been added.sensor, to ensure autonomous anti-collision walking and balance control. During the driving process, it can cross 0.25m high obstacles, climb up slopes and stairs of 30° or more, and map and locate the environment within 30m in front of it, and Display it on the remote terminal. Blind people can interact with the robot through voice, control the robot’s actions, and can also cooperate with the blind stick to exert external force to control the robot to move forward or backward, and the control distance is more than 5 meters.
