"Unlike vehicle assembly, where processes are repeatable, with aircraft the need for lightweight components and high precision means that no two operations are the same. For this reason automation has so far proved too difficult or too costly. Our robot guidance systems overcome these challenges. The investment from the Midlands Engine Investment Fund II will enable us to consolidate our position and start work on the next generation of products to ensure we maintain our position as thought leaders in the industry."
The round was jointly led by Mercia Ventures and Smedvig Ventures to power product development and international growth.
"It is widely accepted that human error is the most prevalent vector for cyber-attacks and is poorly protected against by ineffective training programmes.

James has an incredible reputation as a thought leader in the space and we are excited to partner with him and his team alongside Mercia Ventures."
