• Make sure the computer running ARCx is on Six's Wi-Fi network (AP mode) or on the same network Six joined (client mode).
• If Six does not appear in the address list, type the address by hand. On Windows the scanner only works when that network is set to Private.
• In AP mode the computer has no internet; that is normal. Cloud speech and AI skills need a second connection (Ethernet or the USB Wi-Fi dongle in the box), or put the EZ-B v4 on your home network.

The gait frames are in the wrong action, or the action is not set to repeat. Walking uses the reserved Forward, Reverse, Left, Right and Stop actions. If a movement command does nothing at all, that movement action has no frames yet.

Twelve servos lifting a body draw a lot of current. A tired battery sags and the controller browns out (resets). Charge the battery fully and use the recommended battery for the kit. Slower transitions also reduce the peak current.

Invert that servo on Auto Position's Servos tab instead of re-capturing every frame. For jerky motion use fewer steps with a bigger delay and add a little ramp. If a leg slams at the start of an action, the first frame is far from the current pose; transition into the standing pose first.

Servos holding Six's weight work against gravity and can hum. Press Release in Auto Position to let every servo go limp.

The EZ-B v4 uses two circuit boards that work together during start-up. The top board holds the communication processor and Wi-Fi antenna. The bottom board holds the I/O processor, which handles hardware functions such as port control and the start-up sound. At power on, the communication processor starts first and sends start-up commands to the I/O processor; once the I/O processor answers, the EZ-B finishes starting up and plays the start-up sound.

No start-up sound usually does not mean the speaker is broken. More often it is a sign that the I/O processor is not responding. During connection, the communication processor accepts the connection and performs the first part of the EZB handshake, then hands over to the I/O processor, which must return its firmware ID. If the connection log stops at the firmware ID request and no ID comes back, the I/O processor is not responding, which strongly suggests the bottom board is damaged.

The camera may still work, because the top board's communication processor handles the video stream. A working camera only proves the top board is alive, not that the whole EZ-B is healthy.

The usual cause is electrical damage to the I/O system: ports that were shorted, overloaded, or given too much voltage or current. The EZ-B v4's I/O protection has limits and cannot prevent all damage.

• Computer and software: a computer that runs ARCx (Windows 10/11, Ubuntu 24.04, or a Raspberry Pi with Ubuntu 24.04) or ARC (Windows).
• Workspace: a small table area for assembly and testing.
• Power: servos need plenty of current, so use the recommended battery for the kit.
• Learning approach: build and test in stages: one leg, then several legs, then full walking.

A gait is a handful of poses played in a loop, and Auto Position builds them by posing the robot and pressing Capture, so it is a good first robotics exercise. If you already have an Auto Position configuration for Six from an ARC project, ARCx imports it on the Import/Export Utilities tab.

Yes. Add Camera Source (ezb), a detection skill such as Face Tracking or Color Tracking, and Vision Detection Tracking Script with movement tracking. The tracking skill asks the movement panel to turn and walk toward what it sees, and Auto Position plays the matching gait.

EZ-Robot sells Six on its online store, and it may also be available from other online and local retailers. See Six Hexapod at EZ-Robot.com.
