1.4 Description of the machinery
Spot Dock is a recharging station for Enterprise versions of the Spot robot. Enterprise
Spot has physical modifications on the underside as well as behaviors that enable
docking, charging, and undocking.
Spot Dock automatically supplies power to recharge the robot’s batteries through a
dedicated connection on the rear alignment tower. Charging is automatically enabled
by the Spot robot after properly sitting on the Dock and activating the power flow.
Charge time varies based on battery state and ambient temperature. However, at 25°C,
a nearly depleted battery can be recharged to 80% in 50 minutes.
Refer to Spot Information for Use on the Boston Dynamics Support
Center for Spot robot safety information.

Rear alignment tower detail
When Spot sits down, the connector cover doors open and a connector inside the dock
mates to a connector on the underside of the robot.
Before power flows, an interlock circuit is completed and then the output power from
the dock turns on. When the robot walks away, the interlock circuit is broken and power
from the dock charger is turned off.

2 Product safety overview
Spot Dock must only be used with the Spot Enterprise robot.
2.1 Spot Dock intended use
Charging is fully automated. No manual intervention equipment is required during
operation.
2.2 Restrictions on the environment
Refer to Spot Information for Use on the Boston Dynamics Support Center.
Within the scope of this document, an “industrial environment” is a workplace where
non-trained or non-professional Operators are restricted from access or not reasonably
expected to be present during the robot’s intended tasks and application.
Industrial environments can be structured or semi-structured, provided that the layout,
infrastructure and hardware inside the environment have a designated purpose.
Elements of the layout or objects may be expected to be known or foreseeable by users
as part of their process.
Users are responsible for the condition of the operating environment. In particular,
Users must ensure that:
• A working area for Spot and Spot Dock has been delimited and all Operators and
persons exposed to the robot are notified of this area before usage.
• People operating and observing conform to their employer’s safety guidelines for
the use of PPE.
• Access to the industrial environment is restricted to working adults who have
been informed about the content of this document.
• Public spaces that fail to comply with the restriction from access and are not in
control of trained operators are excluded.
• Untrained personnel and children are excluded from the industrial environment.
• Research laboratories or temporary facilities are eligible for use provided that all
conditions and restrictions apply.

11
Failing to comply with the conditions listed above
about the type of environment, personnel and
condition of exposure to hazards, may expose Users to
risks higher than those estimated for the intended use.
2.3 Misuse
The following behaviors by Users and Operators do not correlate with any operational
need for accomplishing a mission/production objective, and do not constitute an
intended use.
Misuses for Spot Dock include:
• Tampering with the charger
• Tampering with the dock charger connector output pins
• Trying to access the restricted area dedicated to Spot Dock
• Any use other than charging Spot
• Manually intervening while Spot is attempting to dock or undock
• Installing the Spot Dock in a location not properly protected from the weather
Any Spot Dock misuse can potentially cause severe
personal injuries or result in significant material
hazards.
2.3.1 EMC considerations
Spot Dock has been tested for EMC compliance according to standards related to heavy
industrial environments. Spot Dock should be able to withstand EMC disturbances
typically found in industrial environments.
Use of Spot and Spot Dock in environments with EMC
disturbances greater than those tested for can result
in erratic and uncontrolled behavior from the Spot
robot and Spot Dock.
Spot and Spot Dock have been tested in accordance with the Industrial EMC test
standards IEC/EN 61000-6-4 and 61000-6-2.

2.4 Noise
Spot Dock generates a minimal amount of noise. The Dock has two cooling fans so it is
normal to hear fans spinning while the Dock is operating. No special PPE is required as
a result of the noise generated by the Dock.
Do not attempt any troubleshooting with the Spot
robot during docking or undocking operations. Do not
approach the Spot Dock when Spot robot is entering
the Spot Dock restricted area. Do not intervene
without powering off the Spot robot, if present.
2.5 General warnings
• Get help when moving the Spot Dock. The Dock is a
2-person lift due to its relative size and weight.
• Spot Dock must be installed inside a structure that
prevents it from being exposed to rain, sea spray or
wind driven rain as well as excessive dust.
• Spot Dock must be protected from spills and
exposure to excessive humidity.
• Protect the Dock from temperature extremes
outside its operational range.
• Do not manually disable the rear tower interlocks.
This exposes a potential electrical hazard.
• Only trained service personnel should access the
electrical cabinet.
• Keep hands and body away from robot while
docking and undocking.

5 Use of the machine
5.1 Docking in teleoperation
Refer to Spot support articles and documentation on the Boston
Dynamics Support Center for details about operating modes and use of
the tablet controller.
To dock the robot using the tablet controller:
1. Navigate to within 2m of the Spot Dock so that the robot can see the fiducial
image mounted on the Spot Dock fiducial panel.
2. Tap the red plus sign to open the list of Actions.
3. Select Dock from the list of Actions.
4. Tap the fiducial image on the controller — it will be bright green.
The robot automatically approaches the Dock and positions itself over the contact
points before sitting. The robot’s motors power off during the recharging process.
Do not attempt to recover Spot from any instability. Do
not approach Spot to help Spot dock. Do not attempt
any troubleshooting during docking and undocking
tasks.
5.2 Status lights during Spot Dock operation
When the robot is charging on the Spot Dock, lights on the front of the robot indicate
its status:
• When the robot is charging on Spot Dock and still connected to the controller
tablet, the robot’s status lights will blink slowly green, indicating that the robot is
connected to the tablet and that motors may turn on.
• When the tablet is not connected, the robot’s status lights display the moving
rainbow pattern to indicate the robot is powered on and ready to connect.

5.2.1 Checking the battery charge status
The Spot Dock charging indicator light is red while charging and turns green when the
robot is fully charged.
You can also check the battery charge status on the tablet controller:
1. Tap the battery icon on the tablet controller
2. In the battery panel, you can review:
• Estimated time remaining
• State of charge
• Battery temperature
5.3 Undocking in teleoperation
When the robot is docked, the tablet shows the robot’s status, including charge level
and dock ID.
To undock Spot, tap the Undock button on the controller. The robot begins the
undocking process:
1. If the robot’s motor power is on, the undocking button is: Undock.
2. If motor power is off, the undocking button reads: Power On & Undock.
Spot stands and walks straight ahead, away from the dock, and returns control to the
Operator.
Allow automated docking and undocking behaviors
to complete before taking control. To override these
behaviors in progress, press the action bar or move a
joystick. This halts the preprogrammed behavior and
restores direct control to the Operator.
Resuming manual control during undocking may
cause additional hazards
5.3.1 Stopping Spot during the undocking process
Tapping the Stop button during the undocking process has the following effect,
depending on the robot’s progress undocking:
• If robot is still on the dock, it remains on the dock.

Spot Dock Information for Use v1.0

• If the robot is standing over the dock, it remains standing.
• If the robot is walking, it stops and remains standing.
• If the robot is in the process of standing up, it stops and maintains its partially
standing pose.
After tapping Stop, the robot Operator retakes control of the robot by tapping Walk,
Stand, Sit or etc.
If the Spot robot is standing over the docking station
when stopped, immediately redocking may cause
the Spot robot to fall as it attempts to sit on the Dock
contact points.
Operators should either walk the robot off the Dock
completely and then sit the robot down, or use the
automated docking workflow.
5.4 Docking in Autowalk
Docking Actions can be added to an Autowalk mission during the mission recording
process to extend mission capability and autonomy. During mission robot replay, the
robot carries out the docking and recharging Action in the same manner as it performs
other mission Actions.
Refer to Spot support articles, videos, and documentation on the Boston
Dynamics Support Center for details about the Autowalk operating
mode.
Do not attempt to recover Spot from any unset of
instability.
Do not approach Spot during docking or undocking
tasks.
Do not attempt any troubleshooting during docking or
undocking tasks.
