iRROBOT developes and distributes linear servo motors under there own brand called MightyZAP aswell as fitting controlling electronics that can be used for both learning and research. The servo motors have a force between 6N and 100N. The resistant case that is made out of industrial plastic making these enignes dust and water tight and therefore usuable vor a variety of applications. The controlling can be done via PWM, the integrated Half Duplex TTL interface or an RS485 BUS. Both the Half Duplex TTL aswell as the RS485 have a feedback function so that they can not only be controlled but also have their position read out.
