Robotics Kit Calculator
Turn teams, kits per team, spares, and parts into kit and part totals.
What it does
Robotics seasons start with kit math: teams times kits per team plus spares for lost parts and growth. Eight teams at one kit with two spares order 10 kits holding 1,200 parts at 120 each.
The tool above takes teams, kits per team, spare kits, and parts per kit. It returns base kits, total kits, and total parts, so purchase orders and storage bins share one line.
This math fits standard kits with fixed parts lists. It does not fit mixed kit types across age divisions, consumables like batteries and blades, or registration fees beside hardware.
Youth robotics programs frame the same unit: teams of students building from kits through seasons of games and events. Parts counts come from the kit manual for the division entered.
Order spares with the base batch. Mid season kit orders cost shipping twice and stall builds for weeks.
How to use
- Enter team count for the season.
- Enter kits issued per team.
- Enter spare kits for loss and growth.
- Enter parts per kit from the manual.
- Read base kits first for the team issue.
- Read totals for ordering and storage.
Formula
- teams
- Teams outfitted this season.
- per team
- Kits issued to each team.
- parts
- Counted parts in one kit.
Same kit type must apply to all teams. Zero spares returns base as the total. Mixed divisions need one run per kit type.
Worked example
Example: 8 teams, 1 kit each, 2 spare, 120 parts
Teams 8, per team 1, spare 2, parts per kit 120.
- Base: 8 x 1 = 8 kits.
- Total: 8 + 2 = 10 kits.
- Parts: 10 x 120 = 1,200 parts.
- Tool shows base 8 kits, total 10 kits, parts 1,200 parts.
- Storage: 10 kit boxes plus one parts sorter per team.
Reference table
| Spare kits | Kits total | Parts at 120 each |
|---|---|---|
| 0 | 8 kits | 960 parts |
| 2 | 10 kits | 1,200 parts |
| 4 | 12 kits | 1,440 parts |
Limits
- One kit type per run. Mixed divisions need split runs.
- Ignores batteries, tools, and field elements.
- Ignores registration and event fees.
- Parts counts follow the manual for the season.
Common mistakes
- Ordering base kits with no spares for loss.
- Mixing kit types in one parts count.
- Forgetting rookie team growth mid season.
- Counting field elements as kit parts.
- Reordering spares alone with rush shipping.

Questions
How many robotics kits do I order?
Teams times kits per team plus spares. 8 teams at 1 with 2 spare need 10.
How many parts is that?
Total kits times parts per kit. 10 kits at 120 hold 1,200 parts.
How many spares should I keep?
At least 10 to 20% of base for loss plus one per few rookie teams.
Do all teams use the same kit?
Within a division yes. Mixed divisions need one run each.
What about batteries and tools?
Track them separately. Kit math here covers counted parts only.
When should I reorder?
With the base order. Mid season singles cost time and freight.
