Tele earth work system



• This is a system which use stereoscopic pictures, computer graphics andvarious work monitors in a control room located away from hazardous area

to maintain a series of remote operations for the excavation of earth,loading it on trucks and transport it for disposal.

• The main characteristics of this system includes radio controlled work inwhich control room is located 2 KM away; V technologies; remotecontrolled vehicles within a radius of ! KM from communication relay car;"idirectional vehicle for trou"le prevent; glo"al multi media through

communication satellite#

• Tele earth work system which is used with main purpose of manpowersaving, timesaving, improvement of work environment# $t is mainly usedduring earthwork in danger area, restoration construction, gar"ageprocessing plant, nucleus pollution area# etc

• This system is used in Ten%in Motomati, &hima"ra 'agasaki (referenceordered "y ministry of construction for various )uantity i#e# *+, !*,and !2+ cum from -an !../ to March !..+.



Main features of o"otization andautomation

• Tele0existence system is a remoteoperation system utilizingstereoscopic image and othervirtual reality 1V technologiesallows the operator in the controlroom to remotely control

operations at the site feeling#

• 3idirectional vehicle controlsystem controls vehicles "y"idirectional control and vehicleinformation#

• 4udio video transmission systemprovides the operator with audioimage information re)uired forremote control#

• emote survey system uses a 5(&and an automatic tracking totalstation

• Vehicle operation and work progresssystem output and display thesurvey information o"tained "y usingthe remote survey system throughprinters and monitoring screens#

• 6xcavation support system providesthe survey information o"tainedthrough the remote survey isautomatically processed and linked

with information on vehicle 1positionand inclination as well asinformation o the planned excavationpro7les, "efore it is provided asstereoscopic visual information forexcavation#

8igging work ro"ot



• 8igging work ro"ot is developed "y Tokyu :onstruction :o# td#

• $t is a remotely controlled ro"ot that is used for digging andloading work# This ro"ot is mainly used for improving workingenvironment, skilled worker saving and la"or saving#

• This ro"ot is applica"le for digging all pits which has diameterthree meters or a"ove and free traveling type of ro"ots isapplica"le regardless of shape of pits# This ro"ot is used in stationfor tunnel driving work of volume ! cum, vertical pit withdiameter /#+ m and depth 2/ m in a)ueduct etc#



Main features of o"otization andautomation

• The operation of the digging ro"otfrom digging earth and sand toloading them is controlled on thecontrol panel provided on the "ody#

• 4n instruction signal sent from theremote control "ox is input to the

control panel through a wiring <saving circuit "y serial transmissionand outputs control signal to themachine from the panel#

• 4n emergency shutdown switch isprovided to stop all functions of thero"ot if danger should "e produced

in operating the remote control "ox#

• The use of wiring saving systemeliminates trou"lesome multi0coreca"le and interference in wirelesscommunication#

• =or digging soil di>erent in property,

e?cient digging work re)uiresad%ustment of digging speed#

• This digging feed rate of the diggingwork ro"ot can "e ad%usted to thatsuita"le for digging the ground#
