## Dataset Description


# Franka Dual-Arm Adjust Bottle Dataset

Lift the bottle head-up from the table.

## Hardware
- **Robot**: 2× Franka Emika Panda (7-DOF dual-arm setup)
- **Cameras**: 3× Intel RealSense D435 (256×256 RGB, front + wrist views)


### State Space (66 dimensions)

**Left Arm (33 dimensions):**
- `tcp_pose` (6): End-effector pose [x, y, z, roll, pitch, yaw] in meters and radians
- `tcp_vel` (6): End-effector velocity [vx, vy, vz, wx, wy, wz] in m/s and rad/s
- `tcp_force` (3): Force at end-effector [fx, fy, fz] in Newtons
- `tcp_torque` (3): Torque at end-effector [tx, ty, tz] in Newton-meters
- `gripper_pose` (1): Gripper opening (0=closed, 1=open)
- `joint_pos` (7): Joint angles [q0-q6] in radians
- `joint_vel` (7): Joint velocities [dq0-dq6] in rad/s

**Right Arm (33 dimensions):** Same structure as left arm



### Action Space (14 dimensions)

**Left Arm (7 dimensions):**
- `delta_pose` (6): Incremental pose change [dx, dy, dz, droll, dpitch, dyaw]
- `gripper` (1): Target gripper state (0=closed, 1=open)

**Right Arm (7 dimensions):** Same structure as left arm
