Abstract
A work assistance robot includes articulated arms, lifting/lowering units that lift and lower the articulated arms, respectively, and a main housing on which the lifting/lowering units are mounted. Each articulated arm has seven or more degrees of freedom including a degree of freedom of an up-and-down movement of the lifting/lowering unit of the articulated arm.
Claims17
A work assistance robot comprising:
- a plurality of articulated arms;
- a plurality of lifting/lowering units configured to lift and lower the plurality of articulated arms, respectively;
- and
- a main unit on which the plurality of lifting/lowering units are mounted,
- wherein each of the plurality of articulated arms has seven or more degrees of freedom including a degree of freedom of an up-and-down movement of the lifting/lowering unit of the articulated arm,
- the plurality of lifting/lowering units are arranged adjacent to each other on a top surface of the main unit, and
- a closest joint of each of the plurality of articulated arms to the respective lifting/lowering unit extends vertically from a top surface of the respective lifting/lowering unit such that a rotation axis of the closet joint is along an axis of up-and-down movement of the respective lifting/lowering unit.
4 more elements
A work assistance robot comprising:
- two articulated arms;
- two lifting/lowering units on which the two articulated arms are respectively mounted, the two lifting/lowering units configured to lift and lower the two articulated arms, respectively;
- and
- a housing to which the two lifting/lowering units are mounted,
- wherein each of the two articulated arms has seven or more degrees of freedom including a degree of freedom of an up-and-down movement of the articulated arm,
- wherein each articulated arm is mounted to the respective lifting/lowering unit via a link that extends from the lifting/lowering unit in a vertical direction, and
- wherein when one articulated arm of the two articulated arms is at a position higher than the other arm of the two articulated arms, the one articulated arm is configured to rotate 360 degrees around the housing.
4 more elements
A work assistance robot comprising:
- a housing;
- a first articulated arm;
- a second articulated arm;
- a first shaft connected to the housing and to the first articulated arm and a first motor attached to the first shaft to lift and lower the first shaft so as to lift and lower the first articulated arm in a vertical direction with respect to the housing;
- and
- a second shaft connected to the housing and to the second articulated arm and a second motor attached to the second shaft to lift and lower the second shaft so as to lift and lower the second articulated arm in a vertical direction with respect to the housing,
- wherein the first articulated arm has seven or more degrees of freedom including a degree of freedom of an up-and-down movement of the first articulated arm, and the second articulated arm has seven or more degrees of freedom including a degree of freedom of an up-and-down movement of the second articulated arm, and
- wherein, when the first articulated arm is moved to a position higher than the second articulated arm by the first motor, the first articulated arm is extendable laterally with respect to the housing while overlapping with the second shaft in the vertical direction.
