A kind of handling device with ladder function for smart home
Technical field
The present invention relates to field in intelligent robotics, in particular to a kind of carrying with ladder function for smart home
Device.
Background technique
Why intelligent robot is intelligent robot, this is because it has quite flourishing " brain ".It acts as in brain
It is center, this computer has direct connection with operating its people.Most importantly, such computer can carry out
By the movement of purpose arrangement.Just because of this, we just say that this robot is only real robot, although their appearance
It may be different.
Develop with advances in technology, intelligent robot has been applied in all trades and professions, executes corresponding behaviour instead of people
Make.In the smart home life of people, it usually needs carry some home equipments, at this time intelligent robot energy
It enough substitutes people and executes corresponding carrying operation, especially in the biggish equipment of some weight of carrying, intelligent robot is carried out
Carrying can be effectively saved human cost, realize fast and easily transport.But existing intelligent haulage equipment is mostly
Change in displacement is realized in ground rotation using driving wheel, therefore, intelligent robot is only applicable to be removed on flat ground
Transport work, when encountering ladder or stair, these handling devices are at one's wit's end, moreover, article in the handling process, by
In the corresponding protective device of shortage, when carrying some breakables such as vials, thermos bottle glass liner, china bowl, what these were carried
Article is easy to lead to crack damage because of violent vibration, to cause existing intelligent robot haulage equipment practicability lower.
