Abstract

An apparatus for inputting teaching data for a robot includes a first input interface configured to input teaching data of a path layer; and a second input interface configured to input teaching data of a task layer.

Claims

1. A control apparatus of a robot, the control apparatus comprising:

an input device that receives teaching data of a path layer and teaching data of a task layer, wherein the teaching data of the path layer is produced by a first sensing device that measures rotation angles of joints of a user, and wherein the teaching data of the task layer is produced by a second sensing device that photographs an image of a motion of the user;

a computer processor comprising;

a teaching data interpretation device that interprets the teaching data of the path layer and the teaching data of the task layer; and

a teaching data production device that produces a teaching command for controlling the robot using the teaching data of the path layer and the teaching data of the task layer interpreted by the teaching data interpretation module,

wherein the teaching data interpretation device comprises;

a first interpreter that interprets the teaching data of the task layer into a sequence of the task layer using a preset learning algorithm; and

a second interpreter that interprets the teaching data of the path layer into a robot path in a joint space or workspace of the path layer using a preset algorithm.

2. The control apparatus of claim 1, wherein the first interpreter is configured to reduce a dimension of the teaching data of the task layer to perform a data encoding of the teaching data of the task layer and extract semantics of the task layer from the encoded teaching data of the task layer, and

wherein the teaching command producing module comprises:

a conversion unit configured to produce a semantic sequence using the semantics of the task layer; and

a task sequence producing unit configured to extract a behavior semantic suitable for the semantic sequence from a behavior database having pre-stored behaviors and produce a task sequence for the robot using the extracted behavior sequence.

3. The control apparatus of claim 1, wherein the second interpreter is configured to reduce a dimension of the teaching data of the path layer to encode the teaching data of the path layer and decode the encoded teaching data of the path layer to produce path information, and

wherein the teaching command producing module is configured to produce joint space path information and workspace path information by applying a preset kinematic transformation algorithm to the decoded information.
