Questions and Answers

9.1.

Why can't I connect to a robot?

ExRobotics check whether each robot connects to the server before it's deployed. Therefore
connection issues are often because the control station hasn't connected to the server. The
most common reason is that a customer firewall has blocked access.
The connection to the robot consists of two types, one for the control commands via HTTPS over
TCP and one for very low-latency video signals via WebRTC over UDP. To be able to control the
robot from a computer within corporate networks both connection types need to be allowed by
both the corporate and the computer firewall. Your account manager can advise you of the
Protocols, Ports and IP addresses.
9.2.

Why has my robot stopped working in cold weather?

If the temperature in the electronics box drops below 0⁰C the robot will shut down. There is
protective software to prevent this happening but if necessary relocate the robot somewhere
warmer. When its temperature is above 0⁰C switch the robot off and on again and it should
come back to life.
9.3.

Why doesn't my controller work?

This is usually because your control station thinks it's connected to more than one controller.
(devices like USB mice or keyboards with extra multimedia buttons can be interpreted as
"controllers"). You can check the situation by going to
any additional devices that are identified as controllers. The website also enables you to test
your main controller.
9.4.

How much data will the robot transfer over its wireless connection?

When the robot is "asleep" it transfers around 1GB of data per month. During a mission most of
the data is consumed by the video streams. This typically amounts to 1 GB per hour.
Untick the "keep awake" box when the robot isn't being used. This will shut down the cameras
and gas detectors that use most of the 4G bandwidth. Re-ticking the box will wake the robot.
9.5.

How long will the robot's batteries last?

In operation this depends on usage and the age of the batteries. However the life of a full
battery pack will usually lie between:
90 minutes if a robot's driven continuously.
▪
7 hours if it's static with its sensors on (but no lights).
▪
Usually a robot should be stored on its docking station when not in use so it will be charged via
its induction charger. However sometimes this isn't possible (e.g. during transport). In this
case a full battery pack will last:
2 years if the robot is switched off using its black on/off switch.
▪
2 days if it's static and asleep (i.e. the "keep awake" option on the control station is not
▪
checked).
Never leave the quick charger connected to the robot but not to a power supply. This will
reduce a full battery's life to 6 weeks even if the robot is switched off.
