Blind Pick
Blind Pick
A two-fingered robot arm must pick up a randomly initialized block using only proprioception (gripper position) and touch sensing. During training, it can use multiple privileged RGB camera inputs (two static cameras and one wrist camera).

Scaffolder learns to do spiral search and robustly picks up the block even with perturbations (shown to the left and above).
DreamerV3+BC & Guided Observability
DreamerV3+BC & Guided Observability
Baselines move erratically and frequently push the block far from the workspace or search in unfeasible areas.
Blind Locomotion
Blind Locomotion
A proprioceptive policy must run and jump over randomly sized and positioned hurdles. During training, privileged RGB images of the agent and its nearby hurdles are given, allowing the agent to see obstacles before bumping into them.

Scaffolder bounds to minimize the risk of hitting obstacles and quickly recovers when it does.
Guided Observability
Guided Observability
Guided Observability moves quickly in unobstructed areas but is frequently stopped or slowed by hurdles.

DreamerV3 moves slowly and is easily caught by obstacles.
Blind and Deaf Piano
Blind and Deaf Piano
A pair of 30-DoF Shadowhands must learn to play “Twinkle Twinkle Little Star” using only proprioception in the Robopianist simulator. At training time, the policy has access to future notes, piano key presses, and suggested fingerings, which emulates having vision to see sheet music and hearing to determine which keys were pressed.

Blind and Numb Pen Rotation
Blind and Numb Pen Rotation
A proprioceptive policy must control a 30-DoF Shadowhand to rotate a pen from a randomized initial orientation to a randomized desired orientation using only proprioception and the initial and target pose of the pen. During training, the policy has access to the object pose and touch sensors.

A 13-link gibbon must swing between a fixed set of handholds in a 2D environment using the brachiation simulator. To simulate imperfect sensors on a robotic platform, noise is added to the target observations, while privileged observations represent true simulator states.

Both Scaffolder and Guided Observability learn efficient, swinging brachiating motions that closely mimic that of a Gibbon.
DreamerV3 and Informed Dreamer can swing between the handholds but use inefficient motions that incur large energy costs.
Wrist Camera Pick-and-Place
Wrist Camera Pick-and-Place
A proprioceptive policy with an active-perception wrist camera must pick and place a randomly positioned block into a randomly positioned bin. During training, the policy has access to multiple informative, statically-placed cameras.

Scaffolder quickly locates the block and goal location with its active-perception wrist camera. DreamerV3 locates the block relatively quickly but struggles to find the goal location.
Occluded Pick-and-Place
Occluded Pick-and-Place
Rather than employing active visual perception at test time, this task examines the impact of active-perception as privileged sensing at training time. The target policy must use an RGB camera from an occluded viewpoint, alongside proprioception and touch sensing, to pick up a block behind a shelf and place it into a bin. Both block and bin locations are randomly initialized.

DreamerV3+BC locates the block but fails to fully pick it up and even attempts to go to the goal location long after dropping it.
Guided Observability
Guided Observability
Guided Observability locates the block but fails to fully place it on the goal on its first attempt, as its picking is less robust.
Visual Pen Rotation
Visual Pen Rotation
Similar to Blind and Numb Pen Rotation, a 30-DoF Shadowhand must rotate a pen from a randomized initial orientation to a randomized desired orientation. The privileged observations are identical to the blind and numb rotation tasks, but the target policy additionally has access to a top-down RGB camera.
