on the said end for the cameras to see what is in the tower high intensity lights or infrared illuminators will be utilized as water towers do not have internal lighting systems the remote control will have two joysticks which control all of the functions of the arm the up down and side to side movement and up and down the cables mentioned previously the end effecter being used be it the media blaster or the paint gun or robotic arm extend and retract the arm as needed the control box will connected to the arm via a hard wire link which will go run from the control trailer to the arm itself or via wireless link which will increase functionality and allow the user to take the control box out of the trailer and control the arm anywhere within range of the wireless signal for example if the operator needed to be inside the tower on the chair seat or basket attached to the arm the arm could thusly be controlled an end effector is the device at the end of a robotic arm designed to interact with the environment the exact nature of this device depends on the application of the robot in the strict definition which originates from serial robotic manipulators the end effector means the last link or end of the robot at this endpoint the tools are attached in a wider sense an end effector can be seen as the.
