Periodic Reporting for period 1 - AROBMACH (Cognibotics: driving the revolution in accurate robotic machining)

Teaser

Summary

Cognibotics develops and plans to commercialize Millbot â€“ an add-on solution to be used in industrial robots that enables them to reach the minimum accuracy (0.2 mm). The accuracy of 0.2 mm is considered the threshold for wide adaptation of industrial robots in metal machining.
By commercializing a unique solution that enables to combine the advantages of CNC machine systems (high accuracy) and industrial robots (low-price, small size, great reachability and flexibility, better cycle time) Cognibotics will position itself as a game changer and will create its own niche on the market. Cognibotis is a spin-off company from Lund University. We have been present in the robot industry since 2014 providing consulting services and technical discussions with leading robot manufacturers such as ABB, Comau and KUKA. During these years, we have gained an extensive knowledge about the market and its needs as well as built a considerable network of partners and KOLs. The collected knowledge, experience and contacts within the industry will be the base for the successful commercialisation of Millbot.
In the Phase 1 project, we will define the business plan that will guide our commercialization activities of Millbot - the companyÂ´s first own product.
In order to maximise the commercial potential of Millbot (as it will be an add-on solution that can be used in multi-brand industrial robots), it will be initially sold to the robot system integrators. Due to an extremely intensive market competition, the integrators are actively looking for technical innovations that will enable them to gain a competitive advantage.
Our solution will also provide the EU-added value by creating the possibility for the European industrial robot manufacturers to grow rapidly and win competition over the Asian players. Millbot has a great potential to positively impact productivity and competitiveness of the EU:s industry and increase number of the high-qualified jobs within the EU.

Work performed

The feasibility study has shown that is it motivated for Cognibotics to continue investments in the de-velopment and commercialisation of the MILLBOT. The product can add significant value to several industries and can revolutionize accurate robot machining. Cognibotics aims to scale the business and commercialise the MILLBOT with the support from SME Instrument Phase 2 program.

Final results

Millbot is a disruptive, industry first solution, that enables an operational accuracy for industrial robots which has not been able to be achieved before. The solution uses the industrial robotsâ€™ existing sensors and is an add-on to the industrial robots control system. With Millbot, existing industrial robots can achieve a repeatable accuracy better than 0,2 mm, which is a tolerance previously only provided by extremely stiff and very expensive industrial robots or costly CNC machineries. The challenge for in-dustrial robots to achieve acceptable repeatable accuracy is wear and tear in joints, bearings and other mechanical parts and since each deflection is added to the next, industrial robots has not been applica-ble in operations where a repeatable accuracy higher than 0,2 mm is a requirement. The repeatable accuracy is achieved by attaching the industrial robot arm to a fixed point and then measure motor torque and deflections in joints by running the motors in all directions. Data from motors and sensors are fed to MILLBOT which uses highly sophisticated proprietary algorithms to compensate for the deflections.
