✋ Dexterous Manipulation Funded ● Funded Phone on tripod or stable surface Posted 4/28/2026 by DexBo Research Lab

Description

Perform a series of fine motor tasks: thread a needle, button 3 different types of buttons (shirt, jacket, pant), and tie 2 different knots (shoelace knot and bow). Record with a closeup camera angle so finger movements, thread passage, and knot formation are clearly visible.

Recording Specifications

  • Resolution: 1080p minimum, macro or closeup framing, stable camera (no handheld shake)
  • Take Attempts: Show at least 2 takes — failed attempts are valuable too
  • Camera Position: Closeup overhead or front-facing, hands fill frame
  • Task 3 - Tie Knots: Tie at least 2 knots: one simple (shoelace) and one more complex (bow or figure-8)
  • Task 1 - Thread Needle: Thread sewing needle with thread or dental floss — 3 attempts, show success
  • Task 2 - Button Buttons: Button 3 different button types: large shirt button (2min), small jacket button (2min), difficult button (2min)

Quality Criteria
