Mobbot, a unique technology

01

Aerodynamics
of sprayed concrete

CHALLENGE

Generation of waste 20-30%
Dust generation due to insufficient wetting conditions
 

SOLUTION

Modeling, simulation of the Nozzle and Mixing Chamber and prediction of particle speed​
Using modelling, simulation and prediction of the concrete flow enable us to optimum strength performance and control the spraying properties (Particle speed, flow and pressures Homogeneity) 


BENEFITS
Waste and rebound reduction
Concrete strength enhanced
Particle speed optimization

New Automation Technology

CHALLENGE
Shotcrete is managed by feeling not by data.

Sprayed concrete has always had variations due to many parameters related to fresh concrete properties manual spraying process, temperatures etc.
These variations lead to variations in the spraying process and hamper the compaction and therefore the durability of infrastructures.

SOLUTION

Automation of a multi-component platform 

We integrate sensors in the spraying line for real-time control and use artificial intelligence (AI) algorithms to automate the system. The automation system uses a Programmable Logic Controller (PLC) that controls robots, pumps and air compressor. in real time.


BENEFITS
Process control
Concrete strength enhancement

03

Robotic
Fabrication

 

CHALLENGE

Manual labor generates lots of inconsistency in concrete structures.
Formwork takes time and slow down construction process.
 

SOLUTION

Algorithm for 7-DoF trajectory planning

We use a patented spraying head mounted on an industrial robot. 
We utilize various advance frameworks and tools to develop a software which processes the design parameters and generates the spraying trajectory. 


BENEFITS

High flexibility of design
No more formwork 
Time saving and wise usage of workforce

Sustainable Construction Materials

CHALLENGE

Concrete is the second most consumed material on earth. The cement it contains produces 7% of global CO2 emissions and uses sand, a rare commodity. The problem is the overconsumption of this material.

3D concrete printing is currently neither sustainable nor sustainable, because it consumes fine and rare sands and more than 1.5 times the quantities of usual cements, the main source of CO2. This technique very often used as formwork replaces wood and is once again filled with concrete.
It is even less durable if the specially designed mortar is transported thousands of miles to the point where it will be printed.

SOLUTION -  Sustainability and CO2 Footprint

Our additive manufacturing technology using shotcrete allows the use of local and conventional materials with usual amounts of cement. It allows the use of ecological cements and recycled raw materials. We allow a true circular economy of building materials and help our customers to reduce their ecological impact.

The layers sprayed onto each other adhere by kinetic energy, which confers exceptional mechanical properties and durability for additively manufactured elements.

 

Control of the spraying process reduces rebound waste and minimizes the need for concrete.

ADVANTAGES 

CO2 savings> 30% and lower consumption of primary materials 

Use of recycled materials and "green cements"

Circular economy reducing the nuisances linked to the transport of materials

Cost reduction
