GO!
Welcome...
Welcome...
Welcome back to Uniti Update!
Today we're gonna show you the
car that arrived from India
and how we transformed it
into an autonomous vehicle.
And what do we mean with autonomous?
So we wanna start with two
basic autonomous features
The first one being lane keeping
Where the car automatically follows the lane.
The second one being taffic jam mode
Where the car keeps a ceratin distance to the
car in front of you.
And this could acctually cure the traffic jams of the world.
Because when the car keeps a certain distance
And therefore a certain speed
You don't get this
human
break and gas
break and gas
Instead you just keep the speed and everything flows.
So this project had a really ambitious timeline.
And our teams and ourselves have been working
really hard, day and night,
to get it done!
And we're gonna show you the whole process
From recieving the car from India...
... to when we acctually test drive it
autonomously
So that's what we´re gonna show you now!
Let's watch!
That's insane! We're gonna put 8 of theese in here?
400 kg's of batteries!
Otherwise it doesn't work!
We need to figure out
what connections goes where
So now I need to go to the workshop
and get some tools.
Oh did you find wheels?
Yes!
Nice!
Pliers
Pen
Marking tape
Multimeter
Duct tape
Let's go!
It's not super clear I must admit...
It's really fascinating and it looks beautiful.
Some break system might need fixing as well
Some welding
Then we're good to go!
Drilling holes that we're gonna use as guides for the welding.
And we are...
cutting things.
The wiring is almost done
Then we're gonna try it!
I'm gonna check the cell voltage.

They are all good!
So this is the start button!
Right now it's a cable.
We'll see if that works!
So the batteries are in for the first try.
Robin how does it feel?
Great!
So Anton you said nothing will happen?
Well, I think we'll all die!
God knows...
Definitally it will start!
Ok, shall we!?
That's anticlimactic
About that...
So we plugged everything in and expected the car to run.
But that wasn't really the case you see...
All the control systems and dashboards
that we thought would be in the car
when we got it from India
Were severd off and left in India.
So we had to rebuild
the entire system
using
Non generic components
All the car was, was an engine
a motor controller
which we had to hack
And then put it back together
with a completely new system.
So the challenged completely
So our CEO Lewis wrote
the day before on our communications channel
So as you understand
We had to build a system
that we'd thought would be complete when it arrived
So the time frame changed a little bit.
We're trying to figure this out.
We've managed to scale it down.
The indicator status lamp is not on
and it means the motor controller doesn't engage
Probably because the battery mangement system
Doesn't tell the motor controller that it's allowed to drive.
Not so cheerful when you're on the other side of the camera.
Nice and clean!
Cleaning it up!
More parts!
What are you working on?
Now we're getting rid of all the stuff we don't need from the old system
Replacing it with new solid connections
And then wire it up
Get rid of the steering wheel and replace it with a servo
If anybody ever watches this and wonders why it's slightly blurry
It's because the wrong guy is holding the camera!
This wheel here!
Charge wire
Old technology - don't need it!
Here is the driver
It's an electronic power steering
We bought this from a scrap yard
And we'll connect it to the wheels.
So we're gonna weld the
electric autonomous drive platform
The dog's broken!
So now we're gonna move from this...
to this!
testing platform
what you doing there Albin?
Soldering on the hall sensors for the RPM measurements
So there is a hall sensor here and there is gaps
And for every gaps the magnetic field changes
wich means you can measure the speed the wheel has turned.
On both wheels
I'm working for real!
We're trying the stereo camera
It's gonna be the eyes of the car.
It is Saturday night and somethings are working.
You can tell Verena, this is actually her staples holder.
So I just took it off her desk!
For powering the computers!
Then we'll have our steer-by-wire system here!
I really like the control panel!
And the joystick and everything
Excited Mike?
Yes!
Something feels off!
I don't now what it is!
Steering Time!
What are we doing Isak?
Raising the car we're gonna start the motors snart!
When are we gonna start the motor Isak?
Snart!
Step away from the vehicle!
So we're gonna go throught the start up procedure
We've now been working all night it's acctually 2 am
And it's gone great!
Look here!
This is the key switch
You're in neutral here
We wanna be forward
And we have the 12V outlets
To charge the laptop and stuff
And then we have the headlights
so we can show the road in front of us.
So now that the car is in forward mode
We can send a signal to the throttle input
on the motor controller
We plug the plus side in to the throttle
input here
we put this one on
And it's not plugged in
Technical difficulties
If shit goes down you can always press this!
And the motors are disengaged
All I care about is hit that and dive off!
Hello Anton!
How are you today?
Good
Some small stuff needs fixing
Then we can start driving
Kristofer, how's it going?
Yeah it's going well!
This is the new power thingy they invented?
The speedometer.
Power steering
The control panel
Reverse
Neutral
Forward
Autonomous
An inverter
Then we have a 12V plug
Linear potentiometer
To measure the steering output
Then we have the hall effect sensors
What are you guys doing?
We're gonna make some body panels!
This are all dimensions!
This is the steer-by-wire wire
And then back to the brain of the car in the back there
Kristofer
The brain of the car?
It's gonna send Kristofer a 12V signal
Which cable to cut Kristofer?
The green one!
Trying to get them on
We got a supervisor here!
Team work!
Last few screws on the new steering device
It's retro fit from the old Kepler Pod
For a new purpuse
Reuse as we like to do!
It's looking nicer and nicer all the time
but mostly because the stuff we add
It's alive!
Steer by wire man!
We're very proud of this!
Yeah it's great!
Steer by big ass wire
Did you just break that chair!?
No...
You're a vandal!
Ok problem solved, seating is arranged!
No respect to authority here!
We installed some seats
I'm just cutting this one.
To pu a fan in
We're checking on the oscilloscope
that the pulse width modulation signal to the steering servo
is what we think it should be
So thats 12V there
This is not good at all if that's the case
Turn it off!
We're testing if the throttle works
It should!
It has been working before
This is the first test since re-wiring right?
The wheels in the front they turn
And the wheels in the back they burn
So it's a pretty snug fit there...
Turn on the key switch
Forward position
We heard a sound
And drive
Full speed ahead!
We're gonna try out the lane keeping algorithm
And then we're gonna merge that with the cruise control
so that both steering and throttle are controlled autonomously
What distance are we gonna follow?
three meters
Very happy!
Nice!
Way beyond expectations!
And really fun!
So that was pretty awesome right?
In case you're wondering why you are wearing funny hats
It's beacause it's christmas soon
And we usually wear theese funny hats when it's christmas
If you watch this and wonder why the car doesn't resemble the real design at all.
We just want to remind you that this is not the design of the car
It's just a basic platform to test out the autonomous systems
And with that said
We wanna wish you
on behalf of out whole team
A very merry christmas and a happy new year!
And I've acctually programmed some christmas light for Albin.
Year one!
It's a little clinic on how to do
A year one
