Definitions

  • the invention belongs to the technical fields of electronic information, machine vision, automatic control and mechanical design, and particularly relates to a deformable wheeled biped robot with autonomous navigation and walking functions.
  • Bicycles are an environmentally-friendly vehicle that combines human's own athleticism and machinery. Cycling requires the full participation of hands, feet, limbs, torso, and head. During exercise, you can ingest enough oxygen, burn the accumulated fat, and effectively exercise the functions of the internal organs of the human body such as the brain, heart, and lungs. Bicycles powered by human biological energy have almost zero carbon emissions.
  • the combination of public transportation network and bicycle is one of the most effective ways to solve urban traffic congestion. At present, bicycles are becoming the focus of public attention, and new ways of use are constantly being proposed.
  • Random parking is the biggest bottleneck restricting the development of bicycle sharing. After the user arrives at the destination, he parks the vehicle at will. Incorrect parking crowds the sidewalks, public entrances, and blind roads, which affects normal traffic and destroys the urban appearance. Because the parking place is not regular, there are cases where users cannot find a shared bicycle when they need it urgently. In addition, the cost of secondary recycling and re-launch of auto companies has greatly increased, reducing the profit and development space of auto companies. The application of electronic fences, three-dimensional garages, and other technical means in shared bicycle parking seems to be a solution to the problem, but it is actually a difficult compromise and a retrogression of technology. There is no essential difference from a bicycle by bicycle. The solution of random parking needs to find the source of the problem.
  • Piling-free parking is the starting point of the rapid development of GPS positioning bicycles, and it is also a pain point widely criticized. If it is possible to keep bicycle users at their destinations and leave them alone, and to achieve an orderly parking of bicycles, it is the key to the continued survival and development of shared bicycles. However, this seemingly contradictory demand can hardly be achieved only by existing technical means and administrative orders, and new problem solutions need to be provided.
  • Cycling is a service for people before reaching their destination. After arriving at the destination, people need to take care of the bicycles. This reduces to a certain extent people's desire to walk freely and walk freely. For cycling enthusiasts who own private bicycles, they cannot separate their car from their body for a short time and enjoy the fun of free walking.

Description

一种可变形具有自主导航及行走功能的轮式双足机器人 技术领域
本发明属于电子信息、机器视觉、自动控制和机械设计技术领域,具体涉及一种可变形具有自主导航及行走功能的轮式双足机器人。
背景技术
人类诞生之后,主要借助于双腿不断在地球表面迁徙和探索。18世纪末双轮单车产生,19世纪末四轮汽车设计成功,这二者的出现极大拓展了人类在地表活动和探索范围。汽车在行驶速度、里程等方面远远超过单车,但汽车剥夺了人类利用自身运动天赋与周围世界交互的权利。小巧、轻便的单车则是一种可以充分发挥人类自身运动能力的交通工具。近年来,汽车高碳排放导致全球变暖,以及严重的交通雍塞等问题的出现,让人们重新认识单车的独特的存在价值。
单车是一种人类自身运动天赋和机械相结合的环保型交通工具。单车骑行需要手、脚、四肢、躯干、头部的全身性参与。运动过程中可摄取足够的氧气,燃烧囤积的脂肪,有效锻炼大脑、心脏、肺部等人体内部器官的机能。用人体生物能驱动的单车,碳排放几乎为零。用公共交通网与单车相结合是解决都市交通堵塞的最有效方式之一。目前,单车正在成为公众关注的焦点,新的使用方式被不断提出。
结合了GPS定位功能的共享单车是传统单车使用方式的重要升级。传统的私人单车易丢失,携带不方便,难以与公共交通网络融合。公用单车的出现在一定程度上解决了私人单车存在的问题。早期的公用单车为了方便管理,实行一车一桩的方式,即在使用完毕后必须送到指定的车桩。有限的车桩限制了此类公用单车的发展。安装了GPS定位芯片的无桩共享单车出现后,极大方便了使用者,2016年迅速在中国中心城市向周边城市发展,在2017年达到峰值。但随之出现的系列问题,使GPS定位共享单车发展出现阴影。
乱停乱放是制约共享单车发展的最大瓶颈。使用者到达目的地后随意将车辆停放,不正确的停车挤占了人行道,公共出入口,盲道,影响了正常交通,破坏了城市市容。因停放地点没有规律,也出现了使用者在急需时找不到共享单车的情况。此外,车企二次回收和重新投放成本大大增加,降低了车企的利润和发展空间。电子围栏、立体车库等技术手段在共享单车停放方面的应用,表面看起来是一种解决问题的方法,但实际上是对困难的妥协和技术退步。与一车一桩的公用单车没有本质差别。乱停乱放的解决需要寻找问题出现的根源。
无桩停放是GPS定位单车迅速发展的起点,也是其广受诟病的痛点。如果既能保留单车使用者到达目的地撒手不管,又能实现单车的有序停放,是共享单车得以继续生存和发展的关键。而这看似矛盾的需求,仅靠现有的技术手段和行政命令难以实现,需要给出新的问题 解决方案。
全球范围内拥有私人单车的骑行爱好者超过二十亿。他们在使用完单车后也存在携带不方便,需要专用停车场地或专人照管等问题。骑单车出行在到达目的地以前,是车为人提供服务。而到达目的后,需要人照管单车,是人为单车服务。这在一定程度上减少了人希望无拘无束,自由散步行走的兴致。对拥有私人单车的骑行爱好者,无法让自己的爱车与自己身体短暂的分离,享受自由行走的乐趣。
针对共享单车既要无桩随停,又要有序管理这一主要矛盾;或单车把人送到指定地点后,需要专人照管这一问题。本发明提出了一种可变形具有自主导航及行走功能的轮式双足机器人。
