Here, in our series on the EW BrightSparks of 2018, we highlight Hamish Crackett, a Graduate Engineer at Roke where he has already demonstrated his knowledge of electronics, mechanics and software development.
He was assigned to be part of a team working on the GPS-denied, Roke Exploration Navigation System (RENS), within the company’s Computer Vision department.
Hamish’s biggest achievement is the research and engineering of a robotic test rig to provide continuous, repeatable and automated, hardware in the loop experimentation of the navigation system in a scientific manner, combining knowledge in electronics, mechanics and software development.
His nominator, from Roke, writes:
The robotic test rig Hamish built in his first months at Roke has now proven to be instrumental in the progress of the GPS-denied, Roke Exploration Navigation System. He now continues to further enhance the robotic test rig by writing proposals to win internal funding. Most recently this has allowed for the integration of a motion capture system for generating multiple sources of position information.
For example, a requirement for the robotic test rig was its ability to reliably move a 900g sensor head. At the time of Hamish joining Roke, commercially available robotic arms capable of lifting this weight cost in excess of £1000 and the cheapest alternatives were restricted to a maximum weight of 500g and at a cost of greater than £300. This was achieved by using resources on site such as the workshop, and purchasing the cheapest suitable parts and materials, Hamish managed to design and engineer a robotic rig capable of lifting over 1kg for under £300.
