Nerf and back again!

Since our robot base is staying much the same as last years, we have been working on modules that can be switched for each competition.
We need our robot to hold and fire Nerf Darts.

Our excellent team engineer has been working his magic with a 3d printer and a lot of patience to create us just what we need!

Above you can see the 3d rendering of our robot and mount. Below you can see a time-lapse of the mount being printed

This will allow us to hold a standard Nerf Dart Cartridge and fire the darts on command.

The finished mount!

If you are still deciding on motor drivers he recommends getting the motors first and doing a simple stall test with a power supply or multimeter and then getting the motor driver to suit.
