Thanks for your support. Driver 3508D controls four motors in two channals, in other words, you only need two motor icons in the software to control the four motors. For further questions, pls contact us at Teck@robotplayer.com.

Thanks for using the newest RCU!

You don't need a black connector. Most of our motors can be connected to the M1, M2 ports of X1RCU directly, but there is some other things to which you need to pay special attention. Motor 3526 should not be plugged to these two motor ports directly, for motor 3526 gets driver embedded, which will draw power from the RCU, in this case, it (or several motor 3526) probably will exhaust the X1RCU, which cause to the final result: all break down.

It's suggested to use motor with no embedded driver for X1RCU, which will be connected to X1RCU via a driver, in this way, the motor gets power from the external power supply connected to the driver (in other words, the external power supply provides power to both motor and driver), not from the X1RCU, which means, it won't exhaust the X1RCU.

Right now, motor 3526 and motor 3548X are motor with embedded driver. So you can use other motors such as motor 3509 for the X1RCU. For further information, you can refer to the motor manual in our website, or contact us at Teck@robotplayer.com.

For beginners, it's recommended to read this Robot Discovery first http://www.roboexp.com/download/list.asp?id=20.

Other courses will be put on our site step by step. Pls keep an eye on it. Contact us at teck@robotplayer.com if you have further questions.
