PROBLEM TO BE SOLVED: To reduce necessary space for a robot when installed on a floor surface by composing it compact. SOLUTION: For a robot R, a first arm body 3A and a second arm body 3B are provided in parallel at symmetric positions on a rotation base 2. A first drive shaft 31A of the first arm body 3A is connected to a first drive motor 13A through a first shaft 11A, and a second drive shaft 31B of the second arm body 3B is connected to a second drive motor 13B through a second shaft 11B. The second shaft 11B is disposed to surround the first shaft 11A along the same axial line, and a third shaft 21 to connect the rotation base 2 is disposed to surround the second shaft 11B along the same axial line to be connected to a third drive motor 23. |
