01 / OPERATIONAL SHAPE

What this application actually is.

Assembly and dispensing is the most heterogeneous application bracket in the cohort. Cells span snap-fit insertion (force-controlled, slow), screw-driving (force + torque feedback, medium speed), glue / sealant dispensing (precision path-following), and label application (high-speed positioning). The cobot bracket fits short-to-mid-volume assembly where dedicated automation is uneconomic. Payback ranges (10-24 months) reflect the application heterogeneity — high-volume label cells pay back fast, low-volume snap-fit cells more slowly. The cohort's structural argument for this application is force-feedback EOAT: a Robotiq FT-300 or equivalent ($5-6K) gives any cobot the force-control needed for most snap-fit and screw-driving applications, except where sub-Newton precision is required (then KUKA iiwa is the right arm). Dispensing applications have their own software-licence cost in addition to the EOAT — Graco InvisiPac and dispensing pattern software add $8-18K.

02 / LEADING COBOTS FOR THIS APPLICATION

Which cobot fits, and why.

01Universal Robots UR5e

5 kg · 850 mm · $30,000-48,000

URCap force-control accessories (Robotiq FT-300, ATI sensors) make UR5e the safe choice for snap-fit and screw-driving cells. Largest pre-validated assembly software base.

02KUKA LBR iiwa 14 R820

14 kg · 820 mm · $65,000-75,000

Force-controlled precision assembly with sub-Newton resolution. Medical device assembly, electronics, surgical-robot R&D.

03ABB IRB 14000 YuMi (dual-arm)

0.5 kg · 559 mm · $40,000-60,000

Two-handed small-parts assembly. Electronics manufacturing where the application literally needs two arms working in coordination.

04Techman Robot TM5-700

6 kg · 700 mm · $23,000-28,000

Vision-led small-parts assembly. Built-in camera enables presence-and-position verification without a bolt-on system.

03 / THE KILLER LINE ITEM

The cost most buyers underestimate.

Force-feedback EOAT + application software

$8,000-$25,000

Robotiq FT-300 ($5-6K) + assembly software ($3-8K) for snap-fit / screw-driving. Dispensing adds Graco InvisiPac or Nordson licence ($8-18K). For sub-Newton precision, ATI 6-axis FT sensor + dedicated software runs $15-25K.

04 / NO-PAYBACK FAILURE MODES

How assembly and dispensingcells don't earn back.

Trying snap-fit without force feedback

Snap-fit insertion needs force feedback to detect when the part has clicked into place. Cells without it produce inconsistent assembly and require manual rework — defeating the cobot's purpose.

Dispensing path errors not budgeted for re-teach

Glue / sealant patterns require periodic re-teach as the dispensing tip wears. Cells without budgeted re-teach time degrade in pattern quality.

Assuming label-cell speed matches dedicated labeller

Cobot label cells run 8-15 labels/min. Dedicated label machines run 60-120/min. Cobot fit only for low-medium volume.
