To fully realise the environmental and efficiency benefits of electric ROVs, Saab Seaeye has developed the eM1-7 electric manipulator, the world’s most advanced electric manipulator yet.
The Seaeye eM1-7 electric manipulator features an advanced control system allowing both manual and automated operation. Highly accurate, modular electric joints enable enhanced arm control, path planning solutions and actuator re-use. Lift capacity and range of motion exceed the eM1-7 manipulator's hydraulic equivalents, while its aluminium construction ensures high reliability.
Active power management helps regulate demand and manages the regenerative power created with free-fall loads. Dual seven-function electric manipulator configurations provide maximum dexterity.
The Seaeye eM1-7 offers significant advantages over hydraulic alternatives, including more precise positioning with force feedback, increased dexterity, lower water weight and greater reliability - expanding the potential for more autonomous and resident applications.
Advanced arm control comes from position and force feedback, repeatability and in-built intelligence.
Direct end effector control can be achieved when coupled with an intuitive human input device and an inverse kinematics system. Adding our advanced perception systems will lead to a blend of supervised and fully autonomous manipulation. These future control options will be backward compatible and available as upgrades to existing manipulators.
