FAQ

Error compiling the examples
If there are problems compiling the firmware: The provided firmware as well as the examples were developed with Arduino version 1.8.3. Alternatively, you can download it from Arduino.

Sound output too low
Check the setting of the "Vol." trimmer. Build a small "speaker box" into the robot board speaker. This increases the volume and improves the sound considerably.

There is no communication with SPI devices and the user board
Set the Chip Select (CS) pin of the user board to "High" and check your connection at the ISP_U connector and of the used SPI component is supplied with power.

const int chipSelect = 8;
pinMode(chipSelect, OUTPUT);
digitalWrite(chipSelect, HIGH);

The Gamepad does not connect or show any reaction

  • Check the batteries in the transmitter
  • Is the reciever correctly connected to the robot board?
  • Is the "motion firmware" installed on the robot board?
  • Disonnect the power supply of the robot board, switch on the Gamepad and then re-establish the connection to the power supply of the Hexapod (plug in the battery).
  • Is the Gamepad PS2 compatible?
  • Jumper J7 must not be plugged in.

The robot does not react to the gamepad

  • Check the batteries in the transmitter
  • Is the reciever correctly connected to the robot board?
  • Is the "motion firmware" installed on the robot board?
  • Disonnect the power supply of the robot board, switch on the Gamepad and then re-establish the connection to the power supply of the Hexapod (plug in the battery).
  • Is the Gamepad PS2 compatible?
  • Jumper J7 removed?

The robot is not running cleanly

  • Have the legs been calibrated?
  • Are the batteries sufficient strong and charged?
  • Is the robot too heavy?
  • Have the servos been set to the middle position before installation?
  • Are the legs slipping on the ground?
  • Are all screws tightened?
  • Does the machanics wobble?
  • Is the machanics too stiff?

Where can I find the circuit diagram?
The circuit diagram can be found in the "Schematic" folder in the download bundle or can be downloaded from Conrad.

The robot carries out the reset after switching on or getting up

  • Make sure that the battery is fully charged.
  • Is the battery connection cable too thin (< 1.5 mm²) or longer than 20 cm?
  • Is the battery plug soldered on cleanly?
  • If the battery is too small, it cannot supply the necessary operating current for the servos.
  • Is/are there any servo(s) blocked?
  • Does the machanics mave too sluggishly?
