| be classified and recovered from. If you've ridden in a Waymo
| you'll notice it sometimes makes slightly jerky movements and
| hesitates and does things again etc. These are all errors and
| attempted recoveries.
|
| In surgery small errors also happen (this is why you feel so
| much pain even from small procedures) but humans aren't that
| resilient to the mistakes of errors and it's hard to recover
| once one has been made. The consequences are high, margins of
| error are low, and the domain of actions and events really
| really high. Driving has a few possible actions all related
| to velocity in two dimensions. Surgery operates in three
| dimensions with a variety of actions and a complex space of
| events and eventualities. Even human anatomy is highly
| variable.
|
| But I would also expect a robotic AI surgeon to undergo

| has been proven to out perform a surgeon alone. I would also

| I mean, the accountability lies with the company. To take
| your example, Boeing has paid billions of dollars in
| settlements and court ordered payments to recompense victims,
| airlines, and to cover criminal penalties from their
| negligence in designing the 737 Max.
|
| This isn't really that different from malpractice insurance
| in a major hospital system. Doctors only pay for personal
| malpractice insurance if they run a private practice and
| doctors generally can't be pursued directly for damages. I
| would expect the situation with medical robots would be
| directly analogous to your 737 Max example actually, with the
| hospitals acting as the airlines and the robot software
| development company acting as Boeing. There might be an
| initial investigation of the operators (as there is in an
| plane crash) but if they were found to have operated the
| robot as expected, the robotics company would likely be held
| liable.
|
| These kinds of financial liabilities aren't incapable of
| driving reform by the way. The introduction of workmen's
| compensation in the US resulted in drastic declines in
| workplace injuries by creating a simple financial liability
| company's owed workers (or their families if they died) any
| time a worker was involved in an accident. The number of
| injuries dropped by over 90%[1] in some industries.
|
| If you structure liability correctly, you can create a very
| strong incentive for companies to improve the safety and
| quality of their products. I don't doubt we'll find a way to
| do that with autonomous robots, from medicine to taxi
| services.

| Approach:
|
| [Our] policy is composed of a high-level language policy and a
| low-level policy for generating robot trajectories. The high-
| level policy outputs both a task instruction and a corrective
| instruction, along with a correction flag. Task instructions
| describe the primary objective to be executed, while corrective
| instructions provide fine-grained guidance for recovering from
| suboptimal states. Examples include "move the left gripper closer
| to me" or "move the right gripper away from me." The low-level
| policy takes as input only one of the two instructions,
| determined by the correction flag. When the flag is set to true,
| the system uses the corrective instruction; otherwise, it relies
| on the task instruction.
|
| To support this training framework, we collect two types of
| demonstrations. The first consists of standard demonstrations
| captured during normal task execution. The second consists of
| corrective demonstrations, in which the data collector
| intentionally places the robot in failure states, such as missing
| a grasp or misaligning the grippers, and then demonstrates how to
| recover and complete the task successfully. These two types of
| data are organized into separate folders: one for regular
| demonstrations and another for recovery demonstrations. During
| training, the correction flag is set to false when using regular
| data and true when using recovery data, allowing the policy to
| learn context-appropriate behaviors based on the state of the
| system.

|
| In the course of the procedure to remove the tumor near your

| near the penis in order to safely remove the tumor without
| rupturing it. This requires the manipulation of one or both
| testicles as well as the penis which will be accomplished

| signed and approved this morning did not inform you of this
| as it was not known at the time that such a manipulation
| would be required. Out of respect for your bodily autonomy
| and psychological well-being the procedure was aborted and
| all wounds were closed to the maximal possible extent without
| violating your rights as a patient. If you would like to
| continue with the procedure please sign and date the bottom
| of this form and return it to our staff. You will then be
| contacted at a later date about scheduling another procedure.
|
| Please be aware that you are under no obligation to continue
| the procedure. You may optionally request the presence of a
| clergymember from a religious denomination of your choice to
| be present for the procedure but they will be escorted from
| the operating room once the anesthetic has been administered.
