Robot Name: RedBender

Purpose: To be used as a small test platform for testing ideas and developing my software ideas for use with EZ-Builder.

Parts Used: EZ-b v3, firmware 16.6, 2 continuous rotation servos for drive wheels, servo for neck (up/down), wireless camera (EZ-Robot 1st generation), HC-SR04 sonar, servo controller BigGripper (from - discontinued)

Power: 6xAA batteries

Body: The main body is a very old frame built of wood which includes the torso down to the base where the wheels mount. It's something a childhood friend made 20+ years ago. I revived it with a black base coat, Plexiglas front and back panels and aluminum side panels. The arms are for decoration and come from an old 80's "RoboFan". The drive wheels are old Lego Technic wheels with servo horns screwed into them. The head is a plastic box from a dollar store with a printout of Bender's face from the TV show "Futurama".

On the back of the head is a label which includes the firmware revision and date, along with the pin assignments. This is handy since I use him as my testing platform. There are also two caster wheels in the back. I have found two caster wheels make small robots like this more stable.

He is currently decorated for the 4th of July (I had to copy cat what MovieMaker did).

Neat test robot. It is great you could recycle the robot body, probably gives special meaning.
The Robofan arms look awesome. It is a great idea having a diagram pinout on your testbot.
Looking forward to videos. Smile
Thanks for sharing,
Steve S


very vintage,cool Grin


Very Cool Justin! Hey, did you get my email with pin out info on Mini B?



Yep love the old flavoured look... reminds me of the robot J5 (made out of a water heater) in the movie Blank Man Smile


JustinRatliff, very cool evaluation and feature application robot. Happy testing.


@RichardR HAHA! I bet you've seen every movie with a robot in it; I know I have. J5 in BlankMan was pretty funny.

@bret.tallent, Yes I did, thank you. I have not had a chance to check the pin outs, yet. I'm going too soon though! If you come across any other notes please save them for me. Your help has been very appreciated! Smile


@SteveS If you are like me and have several robots in dev at any one time labeling everything and keeping detailed notes is a must. Even if you have one robot it's a good idea. I get 3 hole folders for each of my robots so I can keep my hand scratch notes, diagrams, pinouts, and ideas one spot.

Never underestimate good note taking! Smile


Crap... it was a washing machine.... Still funny movie.. Smile
