技术领域technical field
本发明涉及软体机器人领域,具体涉及了一种基于折纸结构的软体爬行机器人。The invention relates to the field of soft robots, in particular to a soft crawling robot based on an origami structure.
背景技术Background technique
在软体机器人发展领域,传统软机器人采用流体作为执行器的驱动方式,主要通过在高度可变形材料制成的腔室内部施加压力来进行驱动,这种驱动方式往往会因为腔体制造材料可承受最大应变的限制而对软体机器人的整体运动产生影响;采用形状记忆聚合物以及形状记忆合金等智能材料驱动的软体机器人,通常采用对智能材料进行加热或者冷却的方式来使机器人完成一定的动作,但是其可控性较差并且存在运动响应速度慢,存在响应迟滞等缺陷。以上两种传统软体机器人的驱动方式对材料要求较高,同时存在机器人运动模式单一,环境适应性差等缺点。近期使用类硅胶材料浇筑成封闭气腔的软气动执行器驱动的爬行机器人,主要通过更换模具制作具有不同运动模式的气动执行器,如调节执行器气腔内部气压值可实现机器人弯曲或转向,但是其存在模具制造过程复杂繁琐,制作成功率低,通用性差以及类硅胶材料的运动响应时间较长的缺点。In the field of soft robot development, traditional soft robots use fluid as the driving method of the actuator, which is mainly driven by applying pressure inside a chamber made of highly deformable materials. The limitation of the maximum strain has an impact on the overall motion of the soft robot; soft robots driven by smart materials such as shape memory polymers and shape memory alloys usually heat or cool the smart materials to make the robot complete certain actions. However, it has poor controllability, slow motion response, and sluggish response. The driving methods of the above two traditional soft robots have high requirements on materials, and at the same time have shortcomings such as single robot motion mode and poor environmental adaptability. Recently, crawling robots driven by soft pneumatic actuators that use silicone-like materials to form closed air chambers, mainly by replacing molds to produce pneumatic actuators with different motion modes. However, it has the disadvantages that the mold manufacturing process is complicated and tedious, the manufacturing success rate is low, the versatility is poor, and the motion response time of the silicone-like material is long.
针对以上情况发明一种制造方法简单、耗材少、成本低,同时运动响应迅速的新型软气动执行器,以提升软体爬行机器人的性能显得尤为重要。In view of the above situation, it is particularly important to invent a new type of soft pneumatic actuator with simple manufacturing method, few consumables, low cost, and rapid motion response, so as to improve the performance of the soft crawling robot.
