Here you can see Tim working on the hydraulics outside the robot.  Part of the modular approach to Storm means that work on the machine is very easy.  The whole claw mechanism simply slots in and out of the machine

What more could you want ?

Can we crush it - yes we can !

First Generation Storm Pictures - almost 2 years old !

This is the very first picture of Storm ever taken.  With a prototype mocked up lifting arm and the old tattered wheels from the original Storm in place this was the first time that the world saw Storm.... to its credit, nothing has really changed on the chassis since day one.  There have been a few strengthening tweaks made here and there, but what you see here is largely what made its way to the final design. A view from the rear of Storm giving an idea of its proportions.  You can also see how the rear wheels are protected from attack by the side pods (NB rear 'bumper' not in place on this picture). The angled rear armour also allows the robot to be lifted well above horizontal from the front and still retain traction on the floor.  Its hard to get an idea of scale in these images, but Storm is only 65cm wide, 20cm high and about 75cm in length (excluding the claw).

Viewed from the front you can clearly see the main ram in the center, the motors at the back of the robot and the hydraulic valve gear sitting to the left of the rams.  To the front of the robot you can see the bladder exposed (titanium shell removed from around bladder) on the left.  On the right you can see the hydraulics electronics in a vertical box - this is soon to be moved to a less vulnerable position.  The holes throughout the chassis were put in using a CNC system before the chassis was constructed, their size varies depending on the orientation of the member and some sections have no holes at all.  Unfortunately some of the members were welded in the wrong way around.... oops ! Viewed from the rear you can see the motors sitting braced with Titanium rods across the back of the robot.  They drive the large spur gears with sprockets and chains run to the front wheels to provide the 4WD traction.  Behind the motors in the picture you can just make out the hydraulic motor and pump lying across the width of the robot.  The gearboxes are made out of 10mm 2014T aluminum - a very tough variety, the same as Suicidal Tendencies uses for their tracks.

A view from the side with the lifting arm partially raised.  The claw mechanism shown here is not complete as there are steel gussets that support the base of whatever is being crushed.  The claw without these gussets is limited to around 3 tonnes of crush which is sufficient for charity events to put a dent in someone and hold on to them when you pick them up, but not enough to do damage.  With the steel 'forks' in place Storm can apply the full 13 (ish) tonnes of crush through the arm and through a selection of claws that are interchangeable. A view of Storm from the side with the charity event armour on the rear and no armour on the top.  You can clearly see the main ram for the claw lying down the center of the robot and the battery pods on either side.  These usually have a titanium/polycarbonate laminate across them rather than the 6mm polycarbonate seen here.  The wheels are custom made cast Aluminium and the treads are wet go-kart tyres riveted onto the wheels.  We have two sets of 4 wheels for Storm provided by Novacast one of our sponsors - slicks and wets.

Storm Gallery [Actuator Lifter Weapon Mounted]

...

A shot of Storm from the front showing the profiled scoop and the side armour (3mm Steel with 6mm Makrolon).  The scoop is also made from 3mm steel with thick steel sections run down the length of the lifter to provide strength.  The 'air intake' on the top of the robot is to allow the lifter motors to poke slightly through the top of the lifter.  This top section over the motors is 4mm steel. The lifter raised slightly seen from the front and from the side.  Here you can see the construction of the lifter with several pieces of thick steel run under the flat top of the lifter to provide rigidity.  Two actuators raise and lower the lifter which is capable of lifting 4000lbs 400mm in the air in about 3 seconds.  The lifters are run off a Vantec 38E configured for single channel operation.  The actuators have clutches fitted so that when they reach the end of their travel they simple stop moving.  It was this that allowed us to use the Vantec to control the actuators without risking any damage.  It also gives us very fine proportional speed control over what we're doing with the lifters which has proved very useful. 

Storm seen from the rear with the lifters fitter (and the Vantec's removed).  On the right you can see a shot of one side of the drive train.  You can see the motor mounted to the plate.  There is a 11 tooth spur gear on the motor driving the large 110 tooth spur gear.  This is mounted on the same axle (30mm dia Titanium with a 6mm keyway) as the rear drive wheel and a sprocket (which you can just make out in the left picture).  This drives a chain via the tensioner on the far right of the right-hand picture to drive the front wheels on each side.  The tensioners are easily adjustable between fights if required.  In reality however we have never had a need to adjust the tension of the chain as this drive train has proved almost 100% reliable (the only problems we have had with it have been our own fault in not tightening things up!).
