7. Movement Style
Let's determine how your robot will move!
ARC uses movement panels to control a robot's movement. Each ARC project is limited to one movement panel because robots only have one method of locomotion, whether wheeled, crawling, flying, bipedal, etc. The movement panel will register itself with the movement manager service. This allows any robot skill to share the robot's control movements. For example, by adding a Joystick or WiiMote robot skill, the robot can automatically begin moving because the current movement panel handles the movements.
Tip: There is a section for additional details on how ARC uses movement panels and what a movement panel is.
Movement Panel Manual
Advantages of Movement Panels
The convenience of the movement manager service is that any ARC robot project can control any other robot product, irrelevant of the locomotion type (flying, walking, two-wheel driving, etc.). If your ARC project was created for a wheeled robot, you could replace the wheeled movement panel with a drone movement panel. Directions (forward, left, right, etc.) are sent to the movement manager service by any robot skill and handled by the movement panel to have the robot move.
Directions
The ARC framework provides several pre-programmed directions: forward, left, right, reverse, stop, roll right, roll left, up, down, and custom. Movement panels will support the directions that are appropriate to their movement type. For example, an HBridge movement panel will not support UP or DOWN because the robot must have wheels and, therefore cannot fly. You can see what directions are supported on a movement panel by the buttons visible on the interface. This diagram demonstrates how the various directions are expected to behave by movement panels. For example, turning left or right is expected to rotate on the spot. However, to turn slightly right while moving forward will require the robot to move forward with the right wheel speed somewhat slower than the left.
Choose a Movement Panel Type
Here is a list of movement panels for various robot configurations, including robots that walk with gait humanoids/hexapods and more. Select a movement panel to learn how to use it and add it to the project. This list can also be found in the Movement Panels category of the robot skill store or within the ARC software.
The AR Drone Movement Panel allows control of an AR Parrot Drone Quadcopter v1 and v2. The A and Z keys are used for Up and Down when using the keyboard mode. The Arrow keys are used to move the robot Forward, Reverse, Rotate Left, and Rotate Right ARC software enables speech recognition, joystick control, Wii control, web control, and camera tracking - tracking faces, colors, motion, and glyphs. Video Device As mentioned in the Camera Device Manual, the AR Parrot Drone Movement Panel must...
Use this to make your robot walk or move using servos. This movement panel is used for humanoids and hexapods. Create frames and actions to animate the robot servos into pre-defined positions. A gait is the movement pattern of animals limbs, including robots, during locomotion. This robot skill allows robots to customize servo animations for gait locomotion and interacting with the world. Some robots (i.e., humanoids, hexapods, and more) use servos to move with gaits based on speed, terrain,...
A movement panel to control brushless motor controllers. These are used in hoverboards or many other robot types. This uses generic (popular amongst DIY projects) brushless motor controllers. These controllers have a pin for direction, speed, and brake for each motor. Configuration The configuration menu has options to select the ports for generic brushless motor controllers. Select the ports that are connected to the appropriate connections between the EZB and motor controller. *Optional:...
Two or more continuous servos used as a movement panel to move the robot with movement commands.
This movement panel controls two continuous servos, which have continuous rotation. Unlike a Standard Servo, a continuous servo has its internals changed to allow continuous 360 rotation. The two parts that are removed from a standard servo to create a continuous rotation servo are: Mechanical Stop: The spindle will stop if you attempt to rotate a standard servo further than 180 degrees. That is due to a mechanical stop built onto the output gear within the servo. Continuous servos have that...
Use this skill if your robot requires a motor/movement controller that is not supported. You may assign scripts to the Forward, Backward, Left, Right, and Stop commands. Script functions are also available to you to obtain the currently selected speed of both Left and Right wheels. You may modify the speed using SetSpeed(value). The speed values may be altered by any joystick-style skill that affects speed, such as the Joystick in Mobile Interface or a physical joystick using the Joystick...
An advanced custom movement v2 panel with more features than the regular panel for drones, mecanum wheels, and custom drive controllers. This extends the standard custom movement panel by including roll left, roll right, up, and down. You should read about a movement panel to better understand how to implement your custom code. The movement panel description document contains valuable information about how ARC integrates movement panels and how each movement direction should be interpreted....

A movement panel for using a two-channel hbridge that uses DC motors. There is no speed control with this movement panel. The motors will be either ON or OFF. An H-Bridge is an electronic circuit that enables a voltage to be applied across a motor in either direction. Its triggered by TTL signals from a microcontroller, such as an EZ-B. These circuits are often used in robotics and other applications to allow DC motors to run forward and reverse. A Dual H-Bridge (such as the EZ-Robot 2.5 Amp...

The Sphero Movement Panel controls a Sphero over Bluetooth. Connect your computer to the Bluetooth signal of your Sphero. The computer will detect 2 COM ports for the Sphero; only one of them will connect to the sphero - we are unable to determine which COM port is the Sphero, so you have to guess. Sorry about that! Every time you disconnect or reboot the Sphero, the Bluetooth connection must be deleted and re-synced. This means you will have to delete/remove the Sphero Bluetooth device from...

The WowWee MIP robot is hackable with a UART port on the mainboard. Connect the GND, TX, and RX to an EZB’s UART TX and control it from ARC. You can power the EZB with the MIPs onboard batteries, but if more power is needed, an EZ-B v4 + camera, for example, an additional 9 Volt battery, can be used. Any EZB that supports a hardware UART can use this robot skill, such as the ESP32, ESP32-Cam, or EZB v4. The ESP32-Cam is preferred because it’s the smallest and has a built-in camera. *Note:...
