| Phase (Design/Operation) |
design, operation |
(a) The software failure incident related to the design phase can be seen in the article where it mentions that based on initial analysis, one cell of the battery was damaged and sent misleading information to the monitoring equipment. As a result, individual cells became overcharged, leading to the eventual explosion of the RoboSimian robot at Nasa's Jet Propulsion Laboratory [48582].
(b) The software failure incident related to the operation phase is evident in the article when it describes how an intern from the next lab over climbed through a window and sprayed RoboSimian with a CO2 fire extinguisher after the initial battery explosion. However, this method did not extinguish the fire, and water was needed to dissipate the heat. Eventually, firefighters in breathing masks rolled RoboSimian outside and extinguished the fire with water for 30 seconds, highlighting the operational challenges faced during the incident [48582]. |

The articles do not provide information about a software failure incident related to the boundary of the failure incident. |
| Nature (Human/Non-human) |
non-human_actions, human_actions |
(a) The software failure incident occurring due to non-human actions:
The incident involving the RoboSimian robot at Nasa's Jet Propulsion Laboratory was caused by a lithium-ion battery undergoing thermal runaway, resulting in the destruction of the robot. The failure was attributed to one cell of the battery being damaged and sending misleading information to the monitoring equipment, causing individual cells to become overcharged. This non-human action of the damaged cell led to a cascading effect within the battery pack, ultimately resulting in the explosion and fire [48582].
(b) The software failure incident occurring due to human actions:
Human actions played a role in responding to the software failure incident. After the initial battery explosion, an intern attempted to extinguish the fire with a CO2 fire extinguisher, which was not effective. It was later determined that water was needed to dissipate the heat from the fire. Another intern called the fire department, and firefighters eventually rolled the robot outside and extinguished the fire with water. Additionally, researchers were seen working on the robot, swapping out one of its batteries, indicating human involvement in the maintenance and handling of the robot's power source [48582]. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident occurring due to hardware:
- The incident involving the RoboSimian robot at Nasa's Jet Propulsion Laboratory on June 14th was primarily caused by a lithium-ion battery explosion [48582].
- The explosion was triggered by one cell of the battery being damaged and sending misleading information to the monitoring equipment, causing individual cells to become overcharged [48582].
- The battery explosion led to the release of smoke containing hydrogen fluoride, carbon monoxide, and carbon dioxide [48582].
- The interns initially used a CO2 fire extinguisher to try to put out the fire, but water was ultimately needed to extinguish it, highlighting the importance of proper fire suppression methods for such incidents [48582].
(b) The software failure incident occurring due to software:
- The incident was not directly attributed to a software failure but rather to a hardware issue related to the lithium-ion battery explosion [48582].
- There is no mention in the article of any software-related contributing factors that originated in the software itself leading to the incident. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The incident described in the article is not related to a malicious software failure. It was a non-malicious failure caused by a lithium-ion battery undergoing thermal runaway, resulting in the destruction of the RoboSimian robot at Nasa's Jet Propulsion Laboratory [48582]. The failure was attributed to one cell of the battery being damaged and sending misleading information to the monitoring equipment, causing individual cells to become overcharged. This non-malicious failure was a result of a technical issue with the battery rather than any intentional harm to the system. |
| Intent (Poor/Accidental Decisions) |
unknown |
The articles do not mention any software failure incident related to poor_decisions or accidental_decisions. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The articles do not mention any software failure incident related to development incompetence.
(b) The incident involving the RoboSimian robot at Nasa's Jet Propulsion Laboratory was not due to development incompetence but rather an accidental failure caused by a lithium-ion battery explosion during charging. The explosion occurred due to thermal runaway in the battery, where one cell was damaged and sent misleading information to the monitoring equipment, causing individual cells to become overcharged. This accidental failure led to the robot catching fire and required the intervention of interns and firefighters to extinguish the flames [48582]. |
| Duration |
unknown |
The articles do not mention any software failure incident related to either permanent or temporary duration. Therefore, the duration of the software failure incident in this case is unknown. |
| Behaviour |
crash, omission, value, other |
(a) crash: The incident involving the RoboSimian at NASA's Jet Propulsion Laboratory on June 14th resulted in an explosion of the robot while it was being charged. The explosion was powerful, with the force of a stick of dynamite, and caused significant damage. The battery failure led to the destruction of the robot, indicating a crash in the system's functionality as it lost its state and was unable to perform its intended functions [48582].
(b) omission: The battery failure in the RoboSimian incident was attributed to one cell of the battery being damaged and sending misleading information to the monitoring equipment. This led to individual cells becoming overcharged, ultimately resulting in the explosion. The omission of correct information from the damaged cell contributed to the failure of the battery system [48582].
(c) timing: The incident involving the RoboSimian's battery failure did not specifically mention any timing-related failures where the system performed its intended functions either too late or too early. The focus was more on the battery failure leading to the explosion rather than a timing issue [48582].
(d) value: The battery failure in the RoboSimian incident resulted in the system performing its intended functions incorrectly, leading to the explosion and subsequent damage to the robot. The damaged cell providing misleading information contributed to the incorrect functioning of the battery system [48582].
(e) byzantine: The articles did not mention any behavior indicative of a byzantine failure where the system behaves erroneously with inconsistent responses and interactions. The focus was more on the battery failure and subsequent explosion of the RoboSimian robot [48582].
(f) other: The behavior of the software failure incident involving the RoboSimian at NASA's Jet Propulsion Laboratory can be categorized as a catastrophic failure due to the battery explosion. The incident showcased the potential dangers of lithium-ion batteries and the risks associated with their failure, leading to significant damage and the need for emergency response measures [48582]. |
