Robot Arms of ESI consist of up to seven joints, links, payload interfaces, sensors, and avionics. Some robot models are modular. Arms joints can be a combination of rotary and linear joints. Some models are modular. Joint modules can be single-joint or double-joint modules. Sensing provides for positioning accuracy and force control in contact with the environment. The Robot Arms are either tele-operated or autonomous.

Robot Arms of ESI are offered for space and planetary research, mobile platforms, manufacturing, custom robotics, and personal robots. Products are currently deployed in several countries around the world. 

Robot Arms of ESI have the following main features:

-  Modular joints
-  Internal cabling 
-  High payload-to-weight ratio
-  Advanced control methods
-  Vision servo capability
-  Force and Impedance control (on some models)
-  Situational awareness
