[0002] Robots have high working efficiency, good safety performance, and high precision in production and processing. Grasping robots are commonly used in production to grasp and transport goods. When the existing grasping robots grasp objects, they generally adopt the form of bilateral clamping and fixing. On the one hand, there is a lack of fixation on the other two sides, and on the other hand, there is a lack of a bottom supporting structure for the object. After clamping, the object is prone to falling, and the stability is poor. At the same time, the heavy object protection structure equipped on the current grasping robot is prone to interference with the grasping structure when grasping objects, affecting the working efficiency. Therefore, there is an urgent need to design a mobile grasping robot that can overcome the above defects.

[0009] In the above-mentioned mobile grasping robot, the end of the bottom supporting fixed base plate away from the lifting frame has an inclined surface, and the side clamping block and the horizontal pushing block are driven by a cylinder.
[0010] In the above-mentioned mobile grasping robot, the lifting frame and the mechanical arm are driven by an oil cylinder, and the axis center line of the oil cylinder power shaft is perpendicular to the axis center line of the air cylinder power shaft.
[0011] In the above-mentioned mobile grasping robot, the heavy object anti-falling protective device includes an anti-falling receiving platform arranged on the main body seat, and a plurality of air cushion layers are laid on the anti-falling receiving platform.
