This article walks you through adding and managing your kart fleet in ROLLER Karting. You'll add each kart, group karts into categories, record the transponders that identify each kart on track, and take karts in and out of rotation as they're serviced.
About your kart fleet
Every kart a driver can be assigned to has to exist in ROLLER Karting first, because the fleet list is what race control draws on when staff put drivers into karts.
ROLLER Karting calls them vehicles rather than karts, because the same timing setup can be used for a range of experiences, not just go-karting.
Each vehicle record holds three kinds of information:
Identity. The name staff see, the category it belongs to, and the transponders that identify it on track.
Availability. Whether the kart is active and can be assigned to a race, or inactive and out of rotation.
Usage. Running totals for kilometers, laps, and time, which is what maintenance schedules and alerts are built on.
Most venues add the fleet once during installation, then come back to this screen when a kart is added, retired, or has a transponder swapped.
Before you begin
ROLLER Karting is installed and you can sign in as an admin. See Install ROLLER Karting if you haven't completed the install yet.
Your timing source is connected and working, if you want to add karts by auto-detection. See Set up your race track in ROLLER Karting.
Your karts have transponders fitted.
Step 1: Create your vehicle categories
Categories group karts together, for example adult karts and cadet karts. They do two things: they separate karts visually on the racing screen, and they let you schedule maintenance by group, such as servicing cadet karts on Mondays and adult karts on Tuesdays.
Set these up first so they're available when you add karts. Follow the steps below:
From the left menu, go to Settings.
Under the Karts header, select Vehicle Categories.
Select NEW VEHICLE CATEGORY.
Enter a name, for example Adults or Cadets/Juniors.
Save the category.

Step 2: Open the Vehicles list
Your fleet lives under Settings. Follow the steps below:
From the left menu, go to Settings.
Under the Karts header, select Vehicles.
The list shows each kart's status, name, category, timing and speed transponders, and any note. The Auto-Detection panel on the right is where newly detected transponders appear.

Step 3: Add your karts
There are two ways to add a kart, and for a new venue the first is usually faster.
Add karts by auto-detection
With a timing source connected, drive each kart over the timing loop, and it appears ready to add. This saves hunting for transponder serial numbers, which are often buried somewhere in the kart. Follow the steps below:
Drive the kart over the timing loop.
When the transponder appears in the Auto-Detection panel, enter a name for the vehicle.
Select Add.
The kart is added to your fleet using its transponder number as the name. Edit the vehicle to rename it to something staff will recognize, such as #1.
Add a kart manually
If you already know the transponder ID, you can enter it yourself. Follow the steps below:
Select ADD A NEW VEHICLE.
Complete the fields described in Step 4.
Select SAVE.
Step 4: Complete the vehicle details
Whether you're editing an auto-detected kart or adding one from scratch, the same fields apply.
Name: What staff see on the racing screen and in the pit lane, for example #1.
Vehicle Category: The group this kart belongs to, from the categories you created in Step 1.
Status: Set to Active for a kart that can be raced. Set it to Inactive to take the kart out of rotation, which stops it being assigned on the racing screen. An inactive kart has to be made active again here or from the maintenance panel before it can race.
Total KM, Total Seconds, Total Laps: Running usage totals for the kart. These are what maintenance schedules and alerts are based on, for example changing tires every 400 laps.
Total KM Reset At, Total Laps Reset At, Total Seconds Reset At: The point each total was last reset. These work like an odometer reading: when you replace an engine or overhaul a chassis, reset the relevant total so maintenance intervals start again from that point. You can reset them independently or together.
Note: A free-text note for your own reference.
Timing Transponders: The transponder that identifies the kart on track. Type the number and press Enter. Most karts have one, but you can add more than one.
Speed Level Transponders: A second transponder that controls kart speed, used with DeHaardt or CDX slowdown systems. Add it the same way. Leave this empty if your venue doesn't use speed control.
Leaderboard tags: Tag the kart to feed a separate leaderboard, for example a cadet karts leaderboard. Tags are created under Settings > Sessions > Leaderboard Tags.
Select SAVE when you're done.
Step 5: Edit or remove a kart
Fleets change, so you'll come back to this list. From the Actions column on the Vehicles list:
Select the edit icon to change any of the vehicle's details, including swapping a failed transponder for a new one.
Select the delete icon to remove the kart from your fleet.
To take a kart out of rotation temporarily, set its Status to Inactive rather than deleting it. That keeps the kart and its usage history while stopping it being assigned to races.
Frequently asked questions
Do I have to use vehicle categories?
They're not required to race, but they're worth setting up. Categories separate karts visually on the racing screen and let you group karts for maintenance scheduling.
A kart's transponder failed and we've fitted a new one. What do I update?
Edit the vehicle and replace the number in Timing Transponders. The kart keeps its name, category, and usage history.
Can one kart have more than one transponder?
Yes. Most karts have a single timing transponder, but multiples are supported. Venues using DeHaardt or CDX speed control add a second transponder under Speed Level Transponders.
Should I delete a kart or set it to inactive?
Set it to Inactive if the kart is off the track temporarily, for example while it's being repaired. Inactive karts can't be assigned to races but keep their history. Delete only when a kart is permanently gone from the fleet.
Why are the usage totals important?
They're the basis for maintenance. Because ROLLER Karting tracks kilometers, laps, and hours per kart, you can set schedules and alerts against real usage and service a kart before something breaks rather than after.
