SERVO 12.2014 27

My wife often comments that I always seem to have a collection of robots that aren’t quite finished or are in a state of disrepair. She’s my wife, so naturally she’s always right, but in this case having a robot that was a POP (Pile of Parts) paid off.

When Micah from Team Tiki fame was searching for someone going to an upcoming event to test out his new gearmotors, I knew I had the perfect storm. I really wanted to put some new drive motors in my upcoming three pound vertical spinner, Scary! Scary! SCARY!, but I

couldn’t find a suitable motor that provided the torque and speed I was looking for. (Refer to the previous Scary build report for more information on the complete bot.) I also had the Orlando Maker Faire event coming up in six weeks. Micah sent over two complete drivetrain packages which included the gearmotors with tires and hubs attached. The entire combo weighs about 3.0 oz on my unofficial postal scale. The length of the gearmotor is ~ 3.0” including the shaft, and is just shy of 1” wide at the motor with the included heat shrink. The heat shrink is applied by Micah to help secure the motor to the gearbox.
