<p>A robot according to an embodiment includes a base (10), a first structure (11), a second structure (12), and a third structure (13). The first structure (11) is connected to the base (10) to be rotatable about a first axis (A1). The second structure (12) is connected to the first structure (11) to be rotatable about a second axis (A2) orthogonal to the first axis (A1). The third structure (13) is connected to the second structure (12) to be rotatable about a third axis (A3) parallel to the second axis (A2). The first structure (11) and the third structure (13) are formed by using cast materials having a same shape.</p> |
