  • Description:
    • STL and 3MF files and user manual for a proof of concept low-cost 3D printable robotic hand.
      • The user manual, currently under development, will include assembly instructions and a bill of materials for the hardware/components used.
    • The hand is assembled using mostly standard, off-the-shelf components available from typical online retailers including standard micro servos for each finger and thumb base rotation, and metric fasteners and heat inserts.
    • The hand can be printed from PLA, PETG, or other rigid, cost-effective filaments, and the hinges, finger/palm pads are printed from flexible TPU filament.
    • The hand design is ambidextrous, meaning the same 3D printed parts and components can be assembled into either a right or left hand, simplifying assembly.
  •  Specifications:
    • Mechanical:
      • Degrees of freedom:
