The data connection to Trident is a major evolution from the connection setup of the original OpenROV kit. It uses a neutrally buoyant tether to communicate to a towable buoy on the surface (radio waves don't travel well in water) and the buoy connects to the pilot using a long range WiFi signal. Using a wireless towable buoy greatly increases the practical range of the vehicle while doing transects and search patterns since a physical connection between the vehicle and the pilot doesn't need to be maintained. You can connect to the buoy and control Trident using a tablet or laptop from a boat or from the shore... ( preorder $1,199.00 )
CANopen digital servo drives are designed to drive brushed and brushless servomotors in torque, velocity, or position mode and employs Space Vector Modulation (SVM),
which results in higher bus voltage utilization and reduced heat dissipation compared to traditional PWM drives.
