Backorders/Out of stock Items - we have changed things so you can order things that are out of stock.

We accept orders for things that are out of stock. However we will not ship you order to you until we can send it to you all at once. We will hold on to you order until everything on it is available.

  • If you want something urgently only order it if it is in stock
  • If you want something that is out of stock then order it and we will add it to our next monthly order from VEX.
  • If you mix in stock items with out of stock items your order will be held until everything is in stock.
  • We will need payment even though the backorder has not been delivered.

What does the Smart Motor do?

The Smart Motor module converts electrical energy from the battery into rotational energy. Motors are the heart of robots, turning wheels, moving arms, and closing claws. The motors square output socket makes connecting the output shafts easy.

What makes the VEX IQ Smart Motor so smart?

The Smart Motor uses a Texas Instruments MSP430 microcontroller running at 16 MHz to process requests, measure speed and direction, monitor current, and control the motor via an H-Bridge. The H-Bridge, also from Texas Instruments, has automatic over current and over temperature protection. Speed and direction are measured via a built-in quadrature encoder that uses a wheel with tiny slots and light sensors. PID loops are processed internally to precisely control output speed and rotation. Current is measured as well to ensure motors don't get too hot in the heat of a battle. All this technology works together to make a Smart Motor that is simple, flexible, and powerful.

Please note this motor does not come with a Smart Cable 228-2780. These need to be purchased separately
