EW BrightSparks 2018 profile: Hamish Crackett

Electronics Weekly has teamed up with RS Components to showcase the brightest and most talented young electronic engineers in the UK today.

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.
