Soft Robots for Soil Sampling

Abstract

The invention discloses a soft-bodied robot for sampling soil. The soft-bodied robot comprises a sampling pipe, a plurality of driving wheels, a power assembly and hemp ropes, wherein the sampling pipe is of a flexible component, and a base component is arranged in the sampling pipe and is produced from memory alloy materials; the driving wheels can rotate and are movably connected to the inner wall of the sampling pipe at intervals; the power assembly comprises a hot water pump and a cold water pump, and the hot water pump, the cold water pump and the base component are communicated through athree-way valve; and the hemp ropes are mutually connected end to end to form an annular structure and are driven to rotate by the driving wheels. The hot water pump, the cold water pump and the basecomponent are communicated through the three-way valve, so that cold-heat exchange can be realized, and then the temperature of the base component is adjusted; the base component is a memory alloy and has a shape memory function, and the shape of the base component is changed along with a progress pipe and the temperature of water in the progress pipe, so that soil sampling is relatively flexible.

Description

technical field [0001] The invention relates to a soft robot, in particular to a soft robot for soil sampling. Background technique [0002] Solve the difficult problem of accurate collection of soil samples for soil testing, formula fertilization, soil monitoring and other soil and fertilizer work. It is convenient, fast and accurate to collect soil samples, and control the sampling error to the greatest extent. The soft robot can be driven by air, and can bend and twist And grabbing objects, soil sampling through soft robots, soft robots can be used in different sampling places, flexible and reliable. [0003] The soft robot does not connect the hot water pump and the cold water pump to the base through the three-way valve, so it cannot realize cold and heat exchange, and thus cannot adjust the temperature of the base. The base cannot deform with the temperature change. , it is difficult to operate, there is no interval on the inner wall of the sampling tube, and there ar...

Problems solved by technology

[0003] The soft robot does not connect the hot water pump and the cold water pump to the base through the three-way valve, so it cannot realize cold and heat exchange, and thus cannot adjust the temperature of the base. The base cannot deform with the temperature change. , it is difficult to operate, there is no interval on the inner wall of the sampling tube, and there are multiple transmission wheels, and the soil cannot be pulled out through the barbs on the outside of the hemp rope by pulling the hemp rope. Sampling is more troublesome, and it is easy to damage the surrounding soil environment, and the practicability is not strong.
