Problems solved by technology

However, the existing ejection system can only kick the football out in a fixed direction, and cannot complete technical actions such as lobbing and lobbing. At the same time, the electromagnet in the existing ejection system uses a freewheeling diode to solve the strong induced electromotive force when the coil is powered off The problem is that the magnetic energy stored in the coil is released in the form of heat energy during the process, and there is a certain waste of energy

Embodiment

[0037] Such as figure 1 As shown, the electromagnetic ejection system consists of a mechanical structure and a control circuit. The mechanical structure includes a batting structure, an electromagnetic propulsion structure and a lifting structure, and the core of the control circuit is a half-bridge circuit.

[0038] Such as figure 2 , image 3 As shown, the mechanical structure adopts a modular design, which is composed of three parts: the hitting structure 1, the electromagnetic driving structure 2, and the lifting structure 3.

[0039] The ball hitting structure 1 is composed of five parts: a push rod bracket 101, a hitting rod 102, a push rod fixing flange 103, a push rod 104, and a rotating shaft 105. Wherein the push rod 104 is vertically arranged, and the push rod bracket 101 and the push rod fixing flange 103 cooperate concentrically with the push rod 104; the upper end of the push rod 104 is fixed by the push rod bracket 101, and the lower end is fixed by the push...

Abstract

The invention provides a half-bridge circuit energy recovery football robot electromagnetic catapulting system which comprises a mechanical structure and a control circuit, and the mechanical structure comprises a ball hitting structure, an electromagnetic pushing structure and a lifting structure; the control circuit adopts a half-bridge circuit and controls the electromagnetic pushing structureto act to drive the ball hitting mechanism to realize a ball kicking action; the lifting mechanism controls the ball hitting mechanism to move up and down in the vertical direction, the position of aball hitting point is changed, multi-angle ball hitting is achieved, technical actions such as shooting and hanging shooting are completed, and the shooting scoring capacity of the robot is enhanced;after the ball kicking action is completed, the control circuit can recover the magnetic energy of the electromagnet coil, the energy utilization efficiency is improved, the capacitor charging waitingtime is shortened, and more shooting times can be completed within the same time.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to an electromagnetic ejection system for a football robot. Background technique [0002] FIRA International Robot Soccer Federation and RoboCup International Robot Soccer World Cup are currently the most influential football robot competition organizations in the world. These two organizations hold football robot competitions every year, and are committed to promoting the development of robot competition, training and education through competitions and technical exchanges. [0003] The medium-sized group soccer robot competition is a fixed event every year. The projection of the medium-sized soccer robot competition should be greater than 30cmⅹ30cm and less than 50cmⅹ50cm. The height of the robot should not be lower than 40cm and not higher than 80cm. The mass of the robot should not exceed 40kg. The game is played on a field 12 meters long and 8 meters wide, using FIFA standa...
