  • 10" or 5" Deck Riser brackets.
  • Aluminum decks with pre-cut switch mounting holes and wireway.

Bob - 1 Out For a Test Run.

During inital testing, the robot was controlled via bluetooth modem and a smartphone running Android.

The base with the standard REX drive motors is rated to run at about 50ft per minute.

After attempting to work with the electronics tucked down in the front of the base near the motors, they were moved up above the casters where they could be more easily reached.

A prototype board was added in place of the solderless breadboard.  The prototype board has a handy socket to plug a BlueSMiRF bluetooth modem into.
