Applications

4QD started out providing DC motor control for the UK golf cart, model engineering, and electric boat markets but our controllers now go into an amazingly wide variety of applications worldwide.

Just a few of the latest ones that we are proud of include;

  • Film set, TV studio, and special effects projects
  • A heavy handling truck in a nuclear waste facility [and we do mean heavy….16 tonnes]
  • Stage props for theatre productions
  • Cable cameras for stadiums
  • Agricultural machinery [feeding and handling equipment]
  • Formula 1 pit equipment [but we’re sworn to secrecy 😥 ]
  • Military equipment
  • An underwater camera drone
  • Clay pigeon launchers
  • High power mountain bikes [including one with 2 wheel drive!]
  • An autonomous artic explorer
  • Robot wars [house robots and contestants]
  • Electric motorbikes
  • Greenpower cars
  • Numerous university research projects such as the Warwick Rail Challenge

Here are just a few of our favourites but there are a lot more throughout the site…..
