Armtrac 20T Robot
Armtrac 20T Robot
The Armtrac 20T Robot is a flexible, cost effective fully remote controlled Small (Heavy) Unmanned Ground Vehicle (UGV). It can be fitted with a variety of toolkits including a demining flail and rear excavator equipped with different attachments. In C-IED operations, a portable X-Ray machine can be mounted on the front and an IED disruptor can be fitted on the rear arm. It has a diesel 40 HP water cooled Isuzu engine which has a radiator reversing fan to prevent the engine from overheating in very dusty conditions. This engine gives it a forward and reverse speed of 7 KPH and can operate for several hours continuously without refuelling. All hydraulic hoses and couplings are internationally common and as such the machine is easy to run and maintain worldwide.
The Armtrac 20T Robot is capable of performing the following roles:
Conventional Demining & EO Clearance Operations
- Technical Survey and EO Reconnaissance
- Area Reduction
- Mechanical clearance where there is restricted access for larger mechanical equipment
- Vegetation Cutting prior to manual demining
- Small clearance operations
- Support to C-IED operations
- Support to Route Clearance operations
- Surface/Sub-surface IED Disposal
- Mechanical Surrogate Scout for Dismounted Foot Patrols
The Armtrac 20T has heavy duty rubber tracks producing a ground bearing pressure of 3 psi but can be fitted with wider tracks for softer terrain. It is very employable in challenging terrain where larger machines cannot access because it is small, manoeuvrable and can climb, descend and traverse 45° slopes & deep gullies due to its low centre of gravity & power. The UGV itself weighs 1150 Kg.
The Armtrac 20T is operated using a control station. The control station transmits operator demands to the UGV and facilitates operation of the UGV by displaying key vehicle data. The Robot can be fitted with video feedback from up to two on board cameras; one pan & tilt camera positioned on a fixed mast in the centre of the vehicle for situational awareness and a second pan mounted unit positioned on the Excavator/Manipulator Arm to aid detailed remote investigation. When cameras are fitted, the LED display unit will be situated inside a standard Peli-case.
The 1.5 m wide Flail tool (440 Kg) spins at 400 RPM and is attached using a quick hitch coupling. It clears Explosive Ordnance (EO), including anti-personnel mines and Improvised Explosive Devices (IED) by detonation or by shattering the EO so it cannot function. The flail consists of 33 hammers and chains which can achieve clearance depths down to 150 mm depth or 200 mm in softer soil. This tool is also an efficient vegetation cutter up to 35 mm diameter when used in conjunction with manual search and clearance techniques.
The hydraulic Backhoe Excavator can be fitted onto the rear of the Armtrac 20T using a quick hitch system. The backhoe can attach a Grapple or a Manipulator Grab for investigating suspected EO or moving EO up to 180 Kg to a safer location for further investigation or render safe procedures. Alternatively, the excavator can operate a standard Scrape Bucket for exposing buried EO/IEDs or constructing trenches to mitigate the effects of EO. The Manipulator Grab, the Grapple and the Scrape Bucket can all be exchanged rapidly using standard tools.
A Disruptor or Exploder for disposing of surface IEDs can be fitted to the Excavator to give additional capability. To complement this and other requirements, the close up camera system fitted on the Excavator provides a live video link to the operator.
The Armtrac 20T is sufficiently robust and agile enough to move across country and provide a surrogate scout for dismounted foot patrols; in this role it would enhance situational awareness and stand-off detection of threats. However, in mechanised operations, it could equally be transported on a standard trailer towed behind a 4x4 vehicle and be prepared for operations within minutes of identifying a potential threat for survey, investigation, x-ray or render safe.
The Armtrac 20T is inherently flexible for both demining and C-IED operations.
However it is also a powerful workhorse for light engineering task and when a forward mounted bucket (and/or forklift tines) are attached, it can undertake small construction tasks and lift loads up to 300 Kg.
The 1.5 metre wide Rotary Mine Comb can extract anti-tank & anti-personnel mines from 25 cm depth without creating dust and only burning 7 litres of fuel per hour. Armtrac’s Sifter can also extract soil from 30 cm for further inspection, providing total confidence of cleared areas.
When fitted with a portable, real-time x-ray scanning system, the Armtrac 20T is capable of examining the inside of vehicles, including inside their boots and bonnets, remotely. The Robot can place the x-ray generator and the detector panel over the top of parked cars allowing the operator to identify a potential threat from a safe distance during route and other clearance operations.
The recommended 160V generator (left) penetrates 40mm of steel and produces sub-millimetre resolution images using a detector panel 535mm x 412mm (right). The scans can be wirelessly delivered to the laptop imaging station (provided with the scanning package).Armtrac 20T Spec Sheet Armtrac 20T Equipment
The Armtrac 75T-230 is Armtrac’s middle of the range workhorse. Smaller than the Armtrac 400, the 75T still maintains all of the functionality of its bigger brother. With its hydraulically operated 2.2 meter Tiller Rotor, the 75T is capable of clearing 11,000 square meters per hour, to a verified (*CROMAC tested) depth of 35cm. A Flail is also available.
The 75T is designed to destroy & withstand 10kg Anti-Tank mines.
The 75T is fully remote controlled up to 800 meters allowing the Operator to remain at a safe distance while still maintaining 100% control of all the machine’s functions, or alternatively if fitted with its fully armoured, sound proofed & air-conditioned cabin (which can withstand NATO Ball at point blank range), an Operator can maintain a detailed “bird’s eye” view of operations in complete comfort & safety.
The cabin maintains the same design as the Armtrac 400; however it can tilt forward to allow easy access to the engine, hydraulics & electrics for ease of maintenance.
The Armtrac 75T-230 has a telescopic boom to which different clearance toolkits can be attached. This boom can be extended to clear mines and UXO in difficult locations such as on river banks and on inclines, while remaining completely stationary. This is a unique feature to Armtrac tracked machines.
A variety of toolkits are available for clearing landmines and UXO. As well as a tiller and flail, the Armtrac Minecomb can extract buried mines and UXO down to 50. cms. When the Armtrac Sifter is fitted to the rear of the machine, this extracts items & potentially missed ordnance to 50 cms which provides a comprehensive quality assurance tool when used together with a front mounted tiller or flail.
By utilising industry standard quick hitch systems, numerous construction tool attachments can be exchanged for the clearance toolkits. The backhoe excavator can be fitted to the rear of the machines when a demining toolkit is fitted to the front. Alternatively, the backhoe can be fitted onto the boom arm which provides a very versatile and far reaching tool with a standard scrape bucket or a grapple attached for extracting UXO which are difficult to access.
The quick hitch system will accommodate any standard construction tool such as buckets, dozer blades, fork lift tines or power grab, making the Armtrac 75T-230 an extremely versatile & useful machine in and out of high threat areas. The boom arm will lift up to 2.7 tons which makes the Armtrac 75T a powerful workhorse for a wide range of levelling, loading, lifting and construction roles as well as clearing mines, IEDs and UXO. This gives it a “second life” after its clearance role.
The Armtrac 75T-230 is a versatile and flexible multi-role machine. Maintenance is reduced to a minimum with its more reliable hydraulically operated tools but nevertheless, components are available worldwide from JCB. These features, plus the innovative telescopic boom arm make this and our other Armtrac products strong market competitors.Armtrac 75t-230 Spec Sheet with Cab Armtrac 75t-230 Spec Sheet without Cab

There are many different demining and engineering toolkits that can be employed with the Armtrac 100 – 350 as well as tillers and flails. When the Armtrac Sifter or Minecomb is fitted to the rear of the machine, these can extracts items of potentially missed ordnance to 50 cms which provides a comprehensive quality assurance tool when used together with a front mounted tiller or flail. Also buckets and backhoe excavators can be employed with this versatile machine.
As it is fully ‘road worthy’, it can be driven to its destination without the need for special transport requirements. As it is based on a commercial tractor it can be used in the agricultural or construction industry as well as in de-mining. This gives the Armtrac 100 – 350 a “second life” beyond its demining role both in and out of the high threat areas.
The Armtrac 100-350 cabin is quiet, air-conditioned & features a fully adjustable air-sprung seat with a 4-point safety harness, adding to its comfort & safety. There is an additional pilot seat in the cabin for an operator to operate additional remote equipment concurrently with the Armtrac 100 – 350.
In addition the cabin sits on rubber pads keeping vibration & shock to a minimum as well as noise level below 50 decibels. The cabin also features 360 degree all round operator visibility & for additional operator safety an Automatic Fire protection system is fitted for the cabin and engine compartments. The Armtrac 100 – 350 is versatile enough and licensed to tow a trailer loaded with a portacabin and toolkits on commercial tarmac roads at 40 KPH.
The trailer has foam filled tyres (optional, dependent on the threat), a 5 KVA generator and is lowed hydraulically to the ground to allow unloading. The air conditioned portacabin could also house Personal Protection Equipment, Detectors and potentially an Armtrac 20T Robot ideal for Technical Survey and vegetation cutting.
Using this comprehensive demining system, the Armtrac 100 – 350 (the prime mover) can be equipped with a demining tool or an excavator on the front. The Robot can be operated from inside of the air conditioned Control Station situated on the trailer or from inside the Armtrac 100 – 350’s protected cabin.Armtrac 100-350 Spec Sheet

Armtrac Mine Comb
Armtrac Mine Comb
Due to its digging action, the Armtrac Rotary Mine Comb is a unique and innovative method of Anti-Tank mine extraction. It gently lifts buried objects from the soil and pushes them to the side of the vehicles path, where they may be collected and contained or detonated safely.
The Armtrac 20 Robot is the perfect tool for the collection of extracted mines. Two ground engaging rotors each contain four tines which intermesh and counter rotate as the vehicle travels forward. These tines lift and continuously nudge large objects the size of anti-tank mines to the outside edge of the vehicle with little soil movement or creation of unwanted berms.
Because of this method the Armtrac Rotary Mine Comb can operate continuously for many hours and remains relatively unobtrusive of the environment.
The Rotary Mine Comb can be used with a number of different vehicles. It has been integrated onto a small armoured construction style crawler dozer as well as commercial tractors and is designed to fit all Armtrac vehicles. A new hydraulic system is now being manufactured to suite all Armtrac’s 400, 100-350 and 75T-230 vehicles.
The Rotary Mine Comb is currently being operated in Angola, progressing nearly one kilometre per day clearing roads of undetectable AT mines.
For further information on the Rotary Mine Comb, see the Test Report published by Humanitarian Demining
The Armtrac Strimmer is designed as an aid in ground UXO clearance, specifically for difficult to reach areas where none of Armtrac’s other machines are able to reach. As with all Armtrac products, the Armtrac Strimmer is armoured to withstand Anti-tank mines.
The Strimmers single flail header can operate horizontally with an effective 2 meter diameter clearance area, or it can be tilted vertically to apply a direct impact on any difficult or suspicious objects. In the vertical plain the Strimmers 3000RPM flail has an impact force of 80 Tonnes/ square inch, totally destroying anything in its path.
The Armtrac Strimmer uses the same industry standard fittings allowing it to be attached to any variety of appropriate machines including the Armtrac 75T-230 and Armtrac 400. The Strimmer uses the hydraulic connections from the host vehicle, therefore no additional power pack is necessary.
It is most suited for fitment to a long reach excavator, to enable it to reach into difficult areas and slope angles. The digger blade doubles as a protection shield from the flail and debris, as well as to claw and dig rocks and moving banks for the machine to move freely and safely between areas.
The Armtrac Roller System is designed to protect vehicles from the effects of victim operated devices and provides a level of confidence when proving routes for the presence of mines and IEDs. It can be used at up to 50 KPH when fitted to the Armtrac 100 and at lower speed with tracked Armtrac vehicles but another self-weight version of the Roller System can also be used with APCs or MBTs.
It is intended for use when there is a possibility, rather than a probability, of a victim operated device on an intended route. This is a full width proving device using two wheel banks each comprising of 7 rollers. Each roller wheel is made from a polyurethane composite and is puncture proof. The steering system can articulate the Armtrac Roller left or right allowing the system to negotiate moderate corners while still protecting the full width of the prime mover; its linkage arrangement allows each roller wheel to articulate over undulating terrain. Left and right roller banks (of 7 rollers) are identical and interchangeable; they swivel a complete 360 degrees when reversing without interfering with each other. In the event of a significant explosive event, the complete roller bank sheers off the main frame at the weakest point and can be easily replaced by another roller bank. Smaller explosions will only damage a roller which can be replaced.
When used with the Armtrac 100 or other Armtrac tracked variants, hydraulic power from the host vehicle is used to transfer up to 2000 Kg of weight onto the roller wheels in order to generate sufficient force to trigger any victim operated devices present. When not route proving, the rollers can be lifted off the ground to provide greater speed and flexibility.
The self-weight version used with APCs and MBTs is identical to the weight assisted version except that it carries additional weights up to 3 tons. Additional weights can be added or removed to/from both variants depending on both the threat and the terrain. There are different methods of connecting to the prime mover using vertically adjusted ratchets with either flange pins or D shacklesArmtrac Roller Spec Sheet
