The Barnabas Racer is a continuation project for the Barnabas-Bot. This robot is a car that is able to think and act on its own. Students will be review concepts from Barnabas Bot (circuits, coding, mechanical build) and will also be introduced to sensors! This kit includes: electrical parts, continuous servo motors, a car chassis and a motor controller.

The instructions are easy to follow. Customer service, excellent. The support I got when I had a question was very thorough.
I assembled this racer so I could assess it for use with my "quarantined" students. I decided to use the Barnabas Rover instead but this kit had a lot of positive features.
I was drawn to the aluminum frame because it reminded me of the Parallax BoeBot that I had used for years with my high school students. The price is significantly lower than the BoeBot. Assembly was easy as I followed the video directions. I have had a lot of experience using the Arduino so it did not take too long to have it driving, flashing LEDs, and beeping. The only tool needed for assembly, a screwdriver, was provided and no soldering was necessary. It had all of the features I was looking for as an "at-home" project base.
I did find the large swivel wheel to be a little too clunky for the mass of the robot. It appeared to affect the navigation a bit when driving by dead reckoning. That problem goes away when navigation is controlled by sensors. I also had to remove on the of servo motors so I could adjust both to zero out at PWM 90. I saw this as a good troubleshooting opportunity, however, that would be useful in reinforcing how the arduino controlled motion.
I chose the Rover over this kit mainly because it used the arduino Uno instead of the Nano. I prefer the Uno because I use it with multiple class levels and can be swapped out with my current supply.
The customer service has been great. I had my questions answered promptly and was offered assistance with the products and curriculum.
