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 www.arduino.cc.
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 consider-
ably.
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 connections at the ISP-U connector and if 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 receiver correctly connected to the robot board?
• Is the "motion firmware" installed on the robot board?
• Disconnect 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 receiver correctly connected to the robot board?
• Is the "motion firmware" installed on the robot board?
• Disconnect 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?
• Is the jumper J7 removed?
The robot is not running cleanly
• Have the legs been calibrated?
• Are the batteries sufficiently 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 mechanics wobble?
• Is the mechanics 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 www.conrad.com .
