Data
Navigation datasets from a TerraSentia agricultural robot driving under the canopy, extracted from ROS1 bags. Three sources/controllers:
| Config | Episodes | Description |
|---|---|---|
CropFollow++ (cpp) |
143 | Crop-follow / pure-pursuit (logs path) |
CROW (crow) |
31 | iLQR controller (logs crop_lines, goal, ilqr_time) |
LeCropFollow (lecrop) |
137 | MPPI/RL + vision (logs dist_err, head_err, mppi_*, keypoint) |
from datasets import load_dataset
ds = load_dataset("arthurpompeu/lecrop-data", "cpp", split="train")
ep = ds[0]
# ep["rgb"] -> per-episode video (camera)
# ep["odom_pos_x"], ep["odom_vel_x"], ep["cmd_lin_x"], ... -> time series
Structure
- Each row = one episode: a stretch where the robot drove through the field
until it stopped for a while. Episodes were segmented from the (smoothed) odom
speed: "moving" when
v > 0.05 m/s; a new episode is cut when it stays stopped for>= 5 s. A single bag can yield several episodes; episodes shorter than2 sor with< 20 messageswere dropped. Bags without odometry become a single episode (the whole bag). - Each column = one signal (a ROS topic), stored as a list (the time
series for that episode). Topics have different rates, so each one has its own
time vector
*_t(seconds, relative to the episode start) and its own length. - Videos (
rgb,lidar_plot,keypoint_vis_*) are theVideotype (MP4/H.264): one video per episode at ~10 fps, with per-frame times in*_t. The HF viewer renders a player. - Removed: rosbag-level fields (
header,seq,stamp,frame_id,covariance,layout), heavy raw sensors (depth and LiDAR/PointCloud) and plumbing (tf,camera_info).
Note — browsable version. This published version is downscaled for the dataset viewer: videos are re-encoded to 320×180 and each numeric signal is sub-sampled to <= 250 samples per episode. This keeps trends/shapes intact and makes the viewer fast, but it is not full resolution. For training, request the full-rate / 640×360 variant.
Columns
Metadata (scalars): source, episode, bag, duration_s, n_msgs.
Signals (lists; <g>_t = relative time in s for group <g>):

imu_* |
imu_t, imu_acc_{x,y,z}, imu_gyro_{x,y,z}, imu_quat_{x,y,z,w} |

MPPI/RL debug (lists of lists) | /…/rl_debug/* (lecrop) |
keypoint |
vision keypoints (list of lists) | /…/vision/keypoint (lecrop) |
Videos (Video, MP4/H.264, ~10 fps; <g>_t = per-frame time):
| Column | Content | Source |
|---|---|---|
rgb |
RGB camera video | /…/rgb/image_rect_color/compressed (all) |
lidar_plot |
LiDAR plot with crop rows | /lidar_plot (crow) |
keypoint_vis_argmax, keypoint_vis_heatmap |
keypoint-visualization videos | /…/vision/keypoint_vis_*/compressed (lecrop) |
Source-specific columns are null when an episode does not have them (e.g. some
cropfollowpp_lecropfollowbags insidecppcarrylecropcolumns).
