Cordless Drill Construction Set

2025

Concept:

1. Off-season FIRST Robotics
2. Prize given for 'most referenced collaboration' - all teams collaborate and publish openly
3. All team members start Work Log, embed Time Log for logging main achievements and time worked, and use FreeCAD or STEP files to share.
4. 20% score bonus earned from using FreeCAD, so designs are modifiable by other teams
5. Top 12 teams get $1000 USD prize for meeting Requirements. 
6. 12 teams correspond to 12 different tool heads: impact driver, clutched drill head, reciprocating saw, circular saw, small blower, multitool head, router head, heavy duty impact driver, small chansaw, LED light, Power Bank (stacked batteries with inverter and charge controller for solar), and leaf blower
7. Requirements:
   1. Must have lifetime performance - it can break more quickly than professional grade industry standards, but must perform minimum tasks required of each tool - AND must be fixable within minutes by part replacement such that it outlasts proprietary professional grade counterparts overall##Open Source Battery Pack - fittable with 18650 cells without soldering (must have spring-loaded contact mechanism)
   2. Must document production engineering using OSHWA compliant open hardware 3D printers##Interchangeable toolheads
   3. 2 phases: body, and heads##Body - includes battery, handle, trigger with speed control, motor, shaft##Heads - first one is impact drive hear, then clutched drill head, then reciprocating saw, then circular saw, then jigsaw
   4. Battery pack is stackable, so you can piggyback multiple packs for up to 48V power (safe limit)
