Within the limits of each servo is necessary to calculate the maximum range or "step" of all horizontal servos to find the smallest of them and convert it as the maximum of one step. The command is executed at the same time that is, all servos operate simultaneously. Regardless of the number of servos, there is only one time, or one T. The Command format are:ĭata 1500 refers to the servo’ location, in the range 500‐2500.ĭata 100 refers to the time of execution and represents the speed, in the range 100‐9999ĭata 1, 2, and 8 refer to the servo’s channelsĭata 600, 900, and 2500 refer to the locations of the servos that correspond to three channelsĭata 100 refers to the time of execution and represents the speed of three servos. Communication protocol: serial communication (TTL level), baud rate 9600, no check bit, 8 data bits, 1 stop bit To control the servo through the servo controller. The servo controller is a slave device, meaning that it can either accept commands or execute preset commands. Now is time to program the arduino to control the USC. So connecting the USC inside the hexapod with the usb to the program I get all de max and min values of each servo. For example using the mouse to drag the slider in the servo panel (drag the servo panel corresponding to the channel with which the servo is connected). And connect GND pin of USC with arduino.īefore programming with arduino it's necessary to know the limits of all the servos and know the limits values. To connect the USC controller simply connect the rx of the USC to the tx of arduino and the tx pin with the rx pin of the USC. What is marked red in the figure are the servo’s connectors for signal wires (be careful about the direction when connecting to the servo). If the chip power is input through the VSS port, the power supply has to range from 6.5 to 12V. Chip power supply (‐): GND (middle of the blue connecting terminal at Position 3 in the figure) Chip power supply (+): VSS (right of the blue connecting terminal at Position 3 in the figure) For example, if the SG-90 servo has a power supply of 4V‐5V, the servo power supply can use the power source of 4‐5V. Servo power supply’s parameters depend on the parameters of the attached servo. Servo power supply (+): VS (left of the blue connecting terminal at Position 3 in the figure) -Servo power supply (‐): GND (middle of the blue connecting terminal at Position 3 in the figure) The servo controller needs two power supplies: servo power supply and chip power supply. USC 16-channel servo controller, UBEC 8A hobbywing, lipo battery. īread board(Y use one with 700 points).(Each eye needs 32 blue leds and 45 red for the matrix). 14 servos (12 for body and 2 for the jaw).A lot of 3 mm screws with nuts (About 50-55).Sheet of aluminium, and a heatsink from an old car radio.
