Send reinforcement drawings, mat spacing, tying volume and labour cost. Our team reviews suitability and agrees pilot criteria. Price and delivery follow a technical review.
Stage: CAD and simulation review. Physical ties have not yet been tested. Site trials follow bench qualification and safety approval.
Validation & development status
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.
nominal BRep pairs
No unintended intersections >0.01 mm³ in the reviewed set. Not a strength or full continuous-motion test.
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.
Basis: R25-041 and R25-048 verification summaries · 14 Oct 2026. CAD animation shows the layout, not verified autonomy.

Calculate project cost in AED
09Project economics · AED
Measure cost per
accepted tie.
Every starting value is an editable assumption. These are not UAE market prices, a quotation or measured CTN BOT performance.
Calculation method
Accepted output = gross output × uptime × acceptance. Robot hours = scope / accepted output + setup. Costs include operator, maintenance, energy, depreciation, consumables for all attempts and mobilisation. Manual labour uses accepted output per person. Break-even exists only if robot variable cost is lower. Add tax, financing and unmodelled risks to other costs. Robot hours are not the calendar duration of a complete crew.

Site
requirements.
The area is selected from drawings and a site review. A pilot decision follows bench qualification.
Horizontal mats
Prepared support and a continuous route. Vertical reinforcement and arbitrary obstacle avoidance are not claimed.
Ø10 / Ø12 / Ø16
Diameters used in the R25-048 simulation at 200 mm spacing. Simulation conditions, not a certified tying range.
Clearance below the mat
25 mm is a design target. Required clearance must be checked with the exact tying tool, bar diameters and mat deflection before site qualification.
Laps & deflection
Flexible mats, ribbing, protruding wire, edges and combined movements require dedicated tests.
