Hardware circuit and control system design
Abstract
With the progress of human society and the expansion of human's exploration of the
natural world, people have invented all kinds of robots to replace human beings to complete
some relatively dangerous work or difficult problems.Among them, there are three kinds of
long-distance moving methods commonly used in robots, which are wheel type, tracked type
and foot type, and each has its advantages and disadvantages.
1. The wheeled robot can walk quickly on a flat road, but it is difficult to travel in other
muddy and rugged complex terrain, with a large turning radius, poor turning efficiency and
poor flexibility.
2. Compared with traditional wheeled robots, tracked robots can travel in muddy, rough
and complex terrain and turn on the spot, but it is difficult to cross when it encounters
obstacles with a large drop.
3. Foot-type robot can adapt to a variety of complex terrain, especially it has great
advantages over wheeled robot and tracked robot in crossing obstacles. However,the walking
speed is relatively low, and the stability of walking has a great relationship with the
environment. It is difficult to control, easy to roll over, and the stability is relatively poor.
On the one hand, according to the advantages and disadvantages of various types of
robots, this design will combine the wheeled robot and foot robot to produce a robot that can
adapt to a variety of terrains and flexibly transform. This kind of robot can be flexibly
transformed into different forms according to different terrains to learn from each other and
give play to the advantages of different kinds of robots. For example, when traveling on flat
terrain in the form of wheel, the traveling speed is fast and the energy consumption is less
than that of the foot robot. But in the complex terrain can use the foot form to travel, the
flexibility is high and the off-road ability is strong. On the other hand, in addition to the basic
control mode of the upper computer, the visual control mode of hand recognition is also used
to control the movement mode of the robot through the change of hand movements, which
improves the operational diversity of this design.
