+ # Dataset Details
11
+
12
+ This dataset contains paired tactile and force data, intended for use in predicting 3-axis normal and shear forces applied to the sensor's elastomer. We used three different indenter shapes to collect force-labeled data: hemisphere, sharp, and flat. To measure force ground truths, we employed the ATI nano17 force/torque sensor. The protocol consisted of applying a random normal load (up to 5N) followed by a shear load, achieved by sliding the probe 2mm on the sensor's elastomer. An illustration of the protocol is shown below:

15
+
16
+ This dataset is part of TacBench for evaluating Sparsh touch representations. For more information, please visit https://sparsh-ssl.github.io/.
17
+
18
+ ## Uses
19
+
20
+ This dataset includes aligned tactile data, 3-axis force, and slip labels using the DIGIT sensor. It is designed to evaluate the performance of [Sparsh encoders](https://huggingface.co/collections/facebook/sparsh-67167ce57566196a4526c328) in understanding tactile properties such as force estimation and slip detection. Note that slip labels {0: no_slip, 1:slip} were obtain indirectlty via the friction cone method.
21
+
22
+ For more information on how to use this dataset and set up corresponding downstream tasks, please refer to the [Sparsh repository](https://github.com/facebookresearch/sparsh).
23
+
24
+
25
+
26
+ ## Dataset Structure
27
+
28
+ The dataset consists a collection of normal/shear load trajectories for each probe. The structure is as follows:
29
+
30
+ ```bash
31
+ sphere
32
+ ├── batch_1
33
+ │ ├── dataset_digit_00.pkl
34
+ │ ├── ...
35
+ │ ├── dataset_digit_03.pkl
36
+ │ ├── dataset_slip_forces.pkl
37
+ ├── batch_2

44
+ │ ├── dataset_slip_forces.pkl
45
+ │ ...
46
+ sharp
47
+ ├── ....
48
+ ```
49
+
50
+ For each batch:
51
+ - `dataset_digit_xy.pkl`: contains the binarized tactile images only.
52
+ - `dataset_slip_forces.pkl`: it's a dictionary where each key represents a sliding trajectory. Each trajectory has the corresponding force and slip labels.
53
+
54
+
55
+ ```python
56
+ def load_pickle_dataset(file_dataset):
57
+ with open(file_dataset, "rb") as f:
58
+ all_frames = pickle.load(f)
59
+ return all_frames
60
+
61
+ def load_bin_image(io_buf):
62
+ img = Image.open(io.BytesIO(io_buf))
63
+ img = np.array(img)
64
+ return img
65
+
66
+ frames = load_pickle_dataset('sphere/batch_1/dataset_digit_00.pkl')
67
+ img = load_bin_image(frames[0])
68
+ ```
69
+
