This dataset contains sequences of actions, motor angles and pendulum angles as well as velocities for a [rotary inverted pendulum robot](https://github.com/armandpl/furuta). The dataset was collected while training the robot to swing up and balance ([wandb run](https://wandb.ai/armandpl/furuta2/runs/bc2yhhpg)). |
|
Angles are in radian. Velocities were computed from the angles and fed to the policy. |
|
The action maps to the motor voltage with: |
|
```Python |
|
deadzone = 0.1 |
|
center = 0.05 |
|
max_act = 0.9 |
|
if abs(action) > center: |
|
V = np.sign(action) * ( |
|
np.abs(action) * (self.max_act - self.deadzone) + self.deadzone |
|
) * 12 |
|
else: |
|
V = 0.0 |
|
``` |
|
You can open the files using foxglove studio or with the [mcap library](https://mcap.dev/). |
