nominal BRep pairs
No unintended intersections >0.01 mm³ in the reviewed set. Not a strength or full continuous-motion test.
Inside CTN BOT
Tying tools, electronics and drive system beneath a removable shell.
Two tying tools
The tools lower to the rebar intersections. Cycle performance and tie quality are being tested.
Travel across rebar
The wheels use the bars for support. Bar diameter and mesh spacing are reviewed for each site.

Results review
Check tie quality once the task is complete.
CTN BOT is in development. Operating performance is being evaluated.
Two tying tools.
Movement along a horizontal mat and tool positioning at intersections. The operator prepares the area and checks the result.
08Evidence & boundaries
Evidence.
With its conditions.
Baseline CAD: R25-041. Separate running-gear study: R25-048. Results from different revisions do not qualify one machine.
traversals completed
Six upper crossings, approximately 2.04 m. Assumed 30 kg mass in successful nominal cases. 40 kg / 5 N: stalled.
verified physical tests
Actual tie quality, throughput, accuracy, mass, life and safety still require testing.
Simulation conditions & open risks
R25-048: four bounded drives, rigid smooth rebar, imposed masses, friction and resistance. 96/96 isolated returns at 0/5 N are not cement-contamination tests. Gearbox backdrive up to approximately 261 rpm needs OEM review. Stalling persists at 40 kg. Full combined movement, actual currents, heat and strength are unqualified.
