Make sure middle motor is connected to port A, right motor is connected to port B, and left motor is connected to port C.Connect PSP-Nx-v4 to sensor port 1 of the NXT brick using NXT cable.friction into the center holes of the top back of the NXT brick. Insert the unconnected end of each connector peg w.Remove LEGO sound sensor before mounting PSP-Nx-v4.Insert the unconnected end of each cross axle 3M into the top axle holes of the PSP-Nx-v4.Insert a cross axle 3M into each angle element, 90 degrees.friction into each angle element, 0 degrees so that the unconnected end is towards the inside of the technic angular beam 4X4. Connect an angle element, 90 degrees to each end of the other cross axle 3M so that the unconnected end is away form the inside of the technic angular beam 4X4.Connect an angle element, 0 degrees onto each end of one of the cross axle 3M.Insert a cross axle 3M into each end of the technic angular beam 4X4.Parts All part names correspond to those found at If robot is turning too much or too little you can easily change motor degrees parameters in the program.Open Obstacle_Avoidance.ev3 in the EV3 programming environment and download it to the NXT.Make sure NXTSumoEyes block is downloaded and imported into your programming environment.No LEGO sensors are used with the program and are not required for bot function. Make sure right motor is connected to port B, and left motor is connected to port C.Connect NXTSumoEyes to sensor port 1 of the NXT brick using NXT cable.friction/crossaxle into the top side holes on the very front of the robot. Insert the exposed end of the connector bushings w.friction/crossaxle into each cross hole of the NXTSumoEyes. Place technic 9M beam onto the exposed ends of the connector pegs w.friction into holes just in front of the technic 9M beam. Press firmly on all connections to ensure a tight fit.friction into each end of the technic 9M beam from the bottom. Raise the technic 9M beam (already on bot) slightly on each side.friction into one end of each technic 5M beam. All part names correspond to those found at ventories/8547-1
