HD2-S Treaded Robot

 Upgraded LiFePO4 power 25.6V 20Ahrs for the drive. Lithium Ion 11.1V 5Ahrs for the video and control. Provides over 1.5 hours of

continuous driving under standard conditions, If driven intermittently the robot’s video and controls will last over 8 hours depending on the

remote selected.

 The HD2s are made from aluminum, so they will not rust. The HD2-S comes painted flat black

 This robot is also equipped with a roll cage which includes a heavy duty frame structure bent and welded to protect top mounted camera

systems from accidental roll over. If a nose tilt camera is selected, the roll cage can be omitted to keep it low profile.

HD2-S Controllers:

There are many different methods to control a robot. This page is a general overview of the most popular methods SuperDroid Robots offers. We have built many robot controllers using

the methods described below, combinations of the methods (i.e. tethered and wireless). We specialize in customizing the control packages to meet your needs and budget. SuperDroid

Robots has extensive experience implementing all of the options discussed below. Please review the methods below. Most of these controls are offered as standard options on our

Tactical Robots, but if you want a custom control package of combination of controls, just let us know. Wireless control and video monitoring is tricky and can be affected by several

factors such as walls, electrical interference, landscape, other RF interference, etc. We offer many different methods for video and data transmission. The range (distance) you can

achieve is greatly influenced by the above. We also offer many tethered (wired) options where RF is not possible.

Description

This control method is our most popular for

Tactical robots. It is considered an analog

system and does not perform as well as a

digital system, but if very good for most

applications.

Video Transmission: Video is sent back

with a 900MHz transmitter. The receiver is

mounted to the controller and the video is

transmitted to a color LCD.

RC Control: Standard versions include a 5,

6, 7, 8 and 16 Channel 2.4GHz frequency

spectrum control system (searches for best

most reliable channel) with a Fail Safe long

range dual receiver. Typically 4 channels

are used to drive the robot (drive, turn, pan

and tilt). Extra channels are need for zoom

control, lights, remote release hitches, arms,

etc. For our arms we can use a standard 8

channel or we can add 8 more channels. If

only 8 channels are used for an arm we use

a channel to changed modes (i.e. arm mode

and camera mode using only eight

channels, but the arm and drive cannot be

used simultaneously.)

Wi-Fi has been around for a long

time now and is an easy and cost

effective way of controlling a

robot. The main disadvantage is

range. We typically install a

wireless router inside the

robot. The Wi-Fi SSID is

broadcast from the robot once its

power up, then the user connects

the laptop or wireless adaptor to

the router and runs a custom

SuperDroid Robots program to

control the robot and monitor the

video.

Using Wi-Fi, there is not real limit

to the number of channels since

its controls are sent via serial

packet, any number of channels

can be transmitted.

Coded Orthogonal Frequency Division

Multiplexing (COFDM) is virtually identical

to OFDM, except FEC (Forward Error

Correction) is applied to the signal before

transmission. The purpose of FEC is to

overcome errors (lost bits) in transmission

due to lost carriers from fading, noise,

interference (mechanical or harmonic) and

other environmental variables. The main

difference is image quality, especially

while the transmitter is in motion.

Whereas analog video transmission tends

to break up periodically from multipath or

interference, digital systems provide you

with high quality images right until the

edge of reception. The primary

advantage of OFDM over a single-carrier

scheme (AM/FM) is its ability to overcome

severe channel condition (Multipath,

fading, attenuation) without equalization

filters. Channel equalization is achieved

by using many slowly-modulated narrow-

band signals rather than a single rapidly

modulated wide-band signal.

Using COFDM, there is not real limit to the

number of channels since its controls are

sent via serial packet, any number of

channels can be transmitted.

Tethered control is as the name

implies, the robot is tethered. The

obvious advantage of this is there are

no wireless interference issues. The

disadvantage is the robot must pull a

cable behind itself. The tether can be

a network cable (limited to about

100meters) or fiber optic. With a Wi-

Fi or COFDM control, the tethered

option can also be added as an

alternate control method (so

depending on the scenario of when

and where the robot is being operated

it can run either wireless or tethered.

Using a tether, there is not real limit to

the number of channels since its

controls are sent via serial packet, any

number of channels can be

transmitted.

Encryption

(Security)

Video is NOT Encrypted or secure. Anyone

with an analog video receiver can intercept

the video feed.

The digital systems use a secure wireless private connection so video feed

cannot be intercepted.

With a tethered system, nothing is

broadcast wirelessly therefore it cannot

be intercepted unless someone splices

into your tether.

Data

(control)Transfer

Data transfer is one way. From the

remote to the robot.

Data transfer is Two-Way (Bidirectional). The data will be sent to the robot, the robot then responds back to the

remote. Using this method confirms data transmission and can also be used to provide robot voltages, arm positions,

etc.

Video Transfer

Video is one way. From the robot to the remote. Two way video is possible with Wi-Fi or Tethered upon request.

Audio

Audio is possible from the robot to the

remote with optional microphone added.

Audio from the remote to the robot (for

negotiation) is also possible. We supply a

two way radios and mount a PA speaker on

the robot.

Audio from the robot to the

computer is possible with an

optional microphone added.

Audio from the remote to the robot

(for negotiation) is also possible

with an optional PA speaker

mounted on the robot.

Audio from the robot to the computer

Range

Tested urban range 200+ yards (effective

operation range for video and control with

multiple building structures, wireless

interference, etc. Concrete and steel walls

Wi-Fi systems are limited in

range. 300 feet is typical. With

line of site 600 or more feet can

be achieved.

COFDM can work on many different

frequencies. The lower frequencies will

have better penetration. The higher

frequencies will have better line of site

performance. Typical ranges 1000 ft. to 1

Tethered systems provide a clean

signal regardless of RF interference or

shielding. Network cables are limited

to about 100 meters. Fiber Optic

cables are have no limit other that
