for a long period, it can heat. When this occurs, before overheating and being dangerous for either
the user or the robot, red lights on the joystick will blink. This is a warning. Simply put down any
object in the gripper, and bring back the robot to the HOME or RETRACTED positions and wait
until the warning goes away before using the robot.
When lifting weight near the maximum load and reach, if the red lights of the controller blinks,
put down the object in the gripper, and bring back the robot to HOME or RETRACTED position and
wait until the warning goes away before using it.
Note:
During normal operation, the joints are subject to heating. The joints are normally
covered with plastic rings which will protect the user from any danger that may be occurred
by the heating of the metal parts.
The fingers of the robot are made flexible in order to protect the internal mechanism. When using
the fingers to push on objects, the user must take special care not flex the fingers beyond their
maximal opening as this could damage the internal mechanism.
Do not force the fingers beyond their maximal opening as this could damage some internal
components.
Electromagnetic interference from radio wave sources
This section describes electromagnetic interference considerations for the robot.
Even if the product complies with all relevant standards, your robot may still be susceptible to
electromagnetic interference (EMI), which is interfering electromagnetic energy (EM) emitted from
sources such as radio stations, TV stations, amateur radio (Ham) transmitters, two way radios, and
cellular phones. The interference (from radio wave sources) can cause the product to stop moving
for a period of 10 seconds. In this case, the device will simply re-initialize and you will be able to
continue to use it. In extremely rare case, it can also permanently damage the control system.
The intensity of the interfering EM energy can be measured in volts per meter (V/m). The product
can resist EMI up to certain intensity. This is called “immunity level”. The higher the immunity level
is, the greater is the protection. At this time, current technology is capable of achieving at least a
20 V/m immunity level, which would provide useful protection from the more common sources of
radiated EMI.
There are a number of sources of relatively intense electromagnetic fields in the everyday
environment. Some of these sources are obvious and easy to avoid. Others are not apparent and
exposure is unavoidable. However, we believe that by following the warnings listed below, your risk
to EMI will be minimized.
The sources of radiated EMI can be broadly classified into three types:
1.
Gripper-held portable transceivers (e.g. transmitters-receivers with the antenna mounted
directly on the transmitting unit, including citizens band (CB) radios, walkie-talkie, security,
fire and police transceivers, cellular phones, and other personal communication devices). Some
cellular phones and similar devices transmit signals while they are ON, even if not being actively
used.
2.
Medium-range mobile transceivers, such as those used in police cars, fire trucks, ambulances
and taxis. These usually have the antenna mounted on the outside of the vehicle.
3.
Long-range transmitters and transceivers, such as commercial broadcast transmitters (radio and
TV broadcast antenna towers) and amateur (Ham) radios. Other types of gripper-held devices,
such as cordless phones, laptop computers, AM/FM radios, TV sets, CD players, cassette players,
