Hi, I'm Shanna, and we have some advice

00:02
for getting your team ready for the Shell Eco-marathon competition.

00:13
This event requires real dedication,

00:16
so here are a few tips to ensure you're prepared.

00:19
One.

00:20
It's really important to define team roles,

00:23
like appointing a team leader, safety manager,

00:25
logistics coordinator and confident driver.

00:32
It's also a great idea to recruit mentors with prior experience.

00:37
Once your team is in place, the next stage is to define your project.

00:41
Two.

00:42
Before you get started, the team should carefully read the rules.

00:46
If you have any questions, please reach out to us.

00:50
We advise drawing up an accurate budget and fundraising plan.

00:56
Make sure it includes your shipping quote, and contact sponsors early.

01:01
Three.

01:02
Before shipping your vehicle, it needs to be fully built and test driven.

01:07
Try to get several hours of driving in a safe location

01:11
prior to travelling to Shell Eco-Marathon.

01:14
Also, run your own technical inspection

01:17
to be confident your vehicle is compliant before it arrives.

01:22
Please take technical inspection very seriously.

01:25
If your car does not comply with every rule,

01:29
you will not get access to the track.

01:33
Aim to pass technical inspection on the first day.

01:36
Four.

01:39
Please print the required technical documents and bring them with you.

01:44
Digital copies are not accepted.

01:49
All Shell Eco-marathon competition rules and instructions are in English,

01:53
so please ensure your team manager and drivers understand English.

02:00

Hi, I'm Shanna, and we have some technical tips on vehicle design,

00:04
to comply with our rules for Shell Eco-marathon.

00:14
The safety of your driver is a top priority during the competition

00:18
as accidents may happen.

00:21
Yikes!

00:22
Your vehicle's design should keep your driver safe

00:25
in the event of a crash or rollover,

00:27
so here's a bundle of tech tips that apply to all vehicle types.

00:31
Cool, man.

00:33
Every vehicle must have a solid floor

00:35
that completely separates the driver's compartment from the road.

00:41
The vehicle body needs to fully surround the driver,

00:44
so no open-top cars are permitted.

00:46
To protect the driver,

00:48
the vehicle's bodywork should have a solid and sturdy construction,

00:51
so do not use materials like thin film,

00:54
cardboard or fabric.

00:56
Rejected!

00:58
The bodywork also needs to cover all mechanical parts when viewed from above.

01:03
Your vehicle must have a bulkhead

01:05
to separate your driver from the energy compartment

01:08
in the event of a fire.

01:11
There should be no manual access

01:13
from the driver's compartment into the energy compartment.

01:16
No.

01:18
The bulkhead should be made from a fire-retardant material,

01:21
like carbon fibre or sheet metal.

01:23
If you use wood,

01:24
you need to add additional material to the energy compartment, like aluminium.

01:30
Make sure the bulkhead reaches all the way to the top and sides of the vehicle,

01:34
leaving absolutely NO GAPS between the body cover and the bulkhead.

01:42
Try to run wires underneath the bulkhead.

01:44
If you have any gaps, fill them with a fire-retardant material,

01:47
like metal tape, and protect the wires from chaffing.

01:55
If you're building an Urban Concept vehicle,

01:57
keep these additional tips in mind.

02:01
Make sure the wheel covers are integrated into the bodywork.

02:04
Remember, your driver's door opening needs a minimum dimension of 500 x 800 mm...

02:10
...and the chassis and bodywork must not infringe on this space,

02:13
as the driver needs to be able to quickly exit the vehicle.

02:19
We recommend building a door on both sides of the vehicle.

02:22
In fact, two doors will be mandatory beginning in 2019.

02:26
Note that bubble-top openings are NOT allowed!

02:31
Please submit your technical drawings, photographs and/or animations

02:35
of your entire vehicle in advance,

02:37
so that we can notify you if your design is non-compliant.

02:40
For more information, read the Shell Eco-marathon rules carefully!

02:44
Please start your vehicle design early,

02:46
and reach out if you have any questions.

02:49
See you on the track!

Hi, I'm Shanna, and I'm going to give you a few tips

00:06
on vehicle Roll Bars and Safety Belts.

00:16
Unfortunately, collisions do happen...

00:21
...and we want to make sure every driver is safe

00:23
in the event that their vehicle crashes.

00:30
First off, let's take a look at the vehicle roll bar.

00:33
If the car rolls over, your driver will be relying on the roll bar for protection.

00:39
We need to make sure the roll bar extends beyond the driver's shoulders

00:42
when seated in a normal driving position - no slouching!

00:46
Oh, no!

00:47
The roll bar must also have a minimum five-centimetre gap

00:51
around the entire racing helmet.

00:54
It needs to be strong enough to endure at least a 70 kilogram static load,

00:58
and we will test this by applying this load

01:00
in several different directions during tech inspection.

01:04
As for roll bar construction,

01:05
it's fine to use tubular steel or panel-type roll bars

01:09
that are integrated into the chassis.

01:12
Now, let's buckle up and talk safety belts.

01:18
We want to see either a 5-point or 6-point belt system

01:22
with mounting points fitted to the strongest parts of the vehicle

01:25
and according to manufacturers' instructions.

01:27
Yeah!

01:29
The waist straps, which normally contain the locking mechanism,

01:32
should be mounted 90 degrees to the floor for a prototype vehicle,

01:36
or between 45 and 60 degrees to the floor for an Urban Concept vehicle.

01:40
Cool, man!

01:42
The belt should meet in the centre of the lower abdomen.

01:45
Crotch straps should be mounted directly below the bottom of the driver's spine.

01:50
They may fasten directly into the locking mechanism

01:53
or loop through the waist straps and fasten via the shoulder straps.

01:58
Make sure shoulder straps are mounted

01:59
approximately 10 degrees below the shoulder.

02:03
Once your driver's safety belts are tightly fastened

02:06
and you've got excess straps secured, you should be good to go.

02:14
And remember, these safety measures should be in place

02:17
BEFORE your driver begins practicing,

02:20
even prior to arriving at Shell Eco-Marathon.

02:23
They should also wear their one-piece race suit,

02:26
protective gloves and helmet.

02:28
And please practice in a safe area,

02:32
not on public roads!

02:34
Check out Articles 26 and 29 of the rules for more information.

02:38
Buckle up and stay safe out there!

Hi, I'm Shanna, and we have some technical tips

00:03
about the telemetry system that's used for Shell Eco-marathon competitions.

00:15
Telemetry allows us to transmit data about car position, speed and energy consumption

00:20
live to teams and spectators at Shell Eco-marathon events.

00:31
Our telemetry data gives teams information that can help them learn and improve,

00:35
and for spectators it adds excitement,

00:37
as they can see exactly what's happening in real time, while the race unfolds.

00:42
Here's how it works.

00:46
Sensors in the car transmit information to an on-board computer...

00:50
The computer sends information to a cloud-based server...

00:54
The server processes the data...

00:57
...and then fires it back down,

00:59
where students and spectators can see it on displays and on social media.

01:06
Let's look at how the telemetry system monitors energy consumption.

01:11
You'll need a different component

01:13
depending on the energy type of your vehicle.

01:17
For internal combustion engines, the primary sensor is the Liquid Flowmeter.

01:22
It will precisely and accurately measure how much fuel

01:25
flows between the tank and the engine.

01:28
For Battery Electric vehicles,

01:30
a joulemeter measures the electrical energy being used.

01:33
It needs to be positioned between the battery

01:36
and the vehicle's electrical system.

01:39
In the case of internal combustion engine vehicles,

01:42
the starter motor must come after the joulemeter.

01:47
For hydrogen fuel cell vehicles,

01:49
energy consumption is measured by a Hydrogen Flowmeter.

01:53
This sensor tracks how many normal litres of hydrogen

01:56
are consumed by the fuel cell.

01:59
Now, let's take a closer look at the On Board Computer, or OBC,

02:03
that all vehicles will need.

02:04
First of all, the On Board Computer is powered by its own battery,

02:08
which will be supplied by the organisers at the event.

02:12
The computer has several components:

02:14
an external element with GPS, WIFI and cellular antennae,

02:18
and an internal component that connects the sensors and the telemetry battery.

02:23
It's important that the external component has a free view of the sky.

02:29
It must not be covered by any parts of the car.

02:32
Siding can be used around the housing,

02:34
but only if all OBC buttons and LEDs are still easily accessible.

02:40
Yeah!

02:42
Finally, the On Board Computer should also be mounted

02:45
within 10 degrees of horizontal.

02:48
That's it for our Telemetry tech tips.

02:50
As a final reminder, don't forget to keep your components and wiring neat,

02:54
away from moving parts of the car,

02:56
and avoid any electromagnetic interference.

02:58
If you need further help, please check out Articles 80 through 85 of the rules

03:03
or contact the tech team with any questions.

Hi, I'm Shanna, and we have some technical tips about motor controllers

00:04
that you need if you're building a battery electric vehicle.

00:15
For battery electric vehicles, we've banned

00:17
"store bought" motor controllers

00:19
so that teams learn about the requirements of their electric motor.

00:23
Once the control requirements are understood,

00:26
individual system components like a single-board control computer

00:29
and the power driver stage can be specified and integrated into the system.

00:33
If you want to design your own controller or power stages

00:37
and integrate them into a printed circuit board, or PCB, that's great,

00:41
but please ensure that the letters "SEM" are etched onto the PCB

00:46
to identify the board as custom built for the Shell Eco-marathon event.

00:50
And by the way, do not be tempted to buy a controller and modify it

00:54
or just take it out of its packaging,

00:56
our eagle-eyed technical inspectors will spot it!

00:59
We want you to develop the motor controller yourself,

01:02
so this also means we outlaw motor controller evaluation kits

01:05
or the individual kit components, including software.

01:09
For more information on Motor Controllers, please check out Article 67 of the rules.

01:13
Good luck designing your motor controllers!
