How to move multiple joints with PyTorch

Hey Guys.

I control the arm on the simulator by reinforcement learning.
The arm has three joints, and I want to move the each joints -1 °, 0 °, or 1 ° each step.
What kind of neural network can?

class Net(nn.Module):

    def __init__(self, n_in, n_mid, n_out):
        super(Net, self).__init__()
        self.fc1 = nn.Linear(n_in, n_mid) 
        self.fc2 = nn.Linear(n_mid, n_mid)
        self.fc3 = nn.Linear(n_mid, n_out)

    def forward(self, x):
        h1 = F.relu(self.fc1(x))
        h2 = F.relu(self.fc2(h1))
        output = self.fc3(h2)
        return output
