Detects gestures that wore previously trained with gesture_capture.ino After an accelerationThreshold is reached, the sketch begin recording numSamples (119) and then feeds in into TensorFlowLite to predict the gesture.
Uses the on-board IMU to start reading acceleration and gyroscope data from on-board IMU and prints it to the Serial Monitor for one second when the significant motion is detected, it also logs the data to a SD card
Saves each gesture data to a SD card in a separate file "1.csv", "2.csv" etc based on example from https://github.com/arduino/ArduinoTensorFlowLiteTutorials To record the next gesture swipe right with your hand in front of the board, it uses the on board gesture detector to detect GESTURE_RIGHT and to record in the next csv file

Overall, the code provides a framework for controlling a hexapod robot using servo motors and receiving commands wirelessly through a Bluetooth module. It defines different functions for smooth movement, walking gait, initialization, and communication with a remote controller.
- Arduino Mega 2560
- Arduino Mega servo shield
- 18 servo motors (5V), eg: MG995
- hexapod skeleton (kit) which contains laser cut parts
- serial bluetooth module HC-05
- battery (i used LiPo 2S 3000mAH)
- high power step down regulator ( output >= 8A )
Commanding the Hexapod via Bluetooth
To control the hexapod robot wirelessly, you can use a serial remote control application on your Android or iOS device. Follow the steps below to establish a connection and program the buttons in the app to send serial commands to the hexapod:
Pairing with the Bluetooth Module:
- Make sure the Bluetooth module is properly connected to the hexapod robot.
- On your mobile device, go to the Bluetooth settings and search for available devices.
- Pair your mobile device with the Bluetooth module of the hexapod robot.
Programming Button Commands:
- Open the serial remote control application on your mobile device.
- In the app settings or configuration section, locate the button programming feature.
- Assign the following commands to the corresponding buttons:
-
Left: Send the command "80" to the hexapod.
-
Forward: Send the command "90" to the hexapod.
-
Right: Send the command "100" to the hexapod.
-
Left 45 degrees: Send the command "25" to the hexapod.
-
Right 45 degrees: Send the command "155" to the hexapod.
-
Start/Stop: Send the command "s" to the hexapod.
-
Up/Down: Send the command "d" to the hexapod.
Controlling the Hexapod:
- To initiate the hexapod's movement, send the "s" command. By default, it will start walking forward.
- To make the hexapod walk slightly to the left, send the command "80". For a 45-degree left turn, send "25".
- To stop the hexapod's movement, send the command "s". To start again, send "s".
- To make the hexapod walk slightly to the right, send the command "100". For a 45-degree right turn, send "155".
- To make the hexapod sit down or stand up, send the command "d". This will toggle the elevation between sitting and standing positions.
By programming the buttons in the serial remote control application, you can conveniently command the hexapod robot's movements and adjust its elevation wirelessly through Bluetooth.
MegaServo: This library allows the control of multiple servo motors simultaneously. VirtualWire: This library provides support for sending and receiving messages wirelessly using RF modules.
Various global variables and constants are defined, including variables for servo positions, speed factors, delay values, control commands, and flags. Structures:
The code defines several structures to represent different aspects of the hexapod robot, such as actuators, walking steps, servo steps, and remote control commands. Actuator Mapping:
An array named "motors" is defined to store the mapping of actuators. Each element of the array represents an actuator and contains information such as the actuator ID, pin number, direction, middle position, elevation, and side. Walking Steps:
A 2D array named "steps" represents the walking gait of the hexapod. It contains sequences of walk steps for different directions and leg movements.
Initialization (setup) Function: The setup function initializes the serial communication and servo motors. It also initializes the communication for receiving commands from a Bluetooth device and sets the initial values for the remote controller. Main Loop (loop) Function:
The loop function continuously checks for incoming commands from the Bluetooth device.
If the received command is a special function command (e.g., start/stop, up/down), the corresponding action is performed.
If the hexapod is allowed to move, it executes the walkForward function with the given direction and speed factor.
The walkForward function processes the walking gait by calculating the required angles for each actuator based on the direction.
The resetDefaults function resets the hexapod to its default position by smoothly moving each servo motor to its initial angle.
The smoothMove and addSmoothMove functions are used for smoothly transitioning between different servo positions.
The sitDown function is used to make the hexapod sit down by adjusting the angles of the servo motors.
The calculateAngleFromDirection function calculates the angle for a specific actuator based on the direction and actuator configuration. Communication Functions:
The initCommunication function initializes the communication for receiving commands from a Bluetooth device.
The getCommandsBT function reads and processes incoming commands from the Bluetooth device.
