B-BOT: A Bluetooth Controlled Vehicle
Jacobs Institute of Design Innovation • Toy Product Design
B-Bot is a bluetooth controlled toy vehicle designed for both kids and adults. Programmed with four speed variations and designed for easy hand controls, B-Bot can traverse obstacles on tough terrains while warding off enemies almost twice its size! It's a tiny bot with a big personality. With the internal Adafruit Bluefruit LE module, simply connect via bluetooth on your smartphone and take this fun little robot out for a spin!
Ideation & Prototyping
The next step was to 3D model B-Bot's external casing and 3D print using the Ultimaker 2+ Extended.
CAD tool used: Fusion360
Design Concept
Exterior Design
B-Bot's cylindrical body allows for a smooth glide across any surface while sustaining impressive 360 degrees front and back flips. The 3D printed PLA material is lightweight and durable enough to withstand bumps and drops from more than five feet.
B-Bot's little tail extends out to assist in balancing when going up and down inclines. Rubber bands are stretched around the wheels to magnify traction. The eyes function as push buttons for easy on/off activation (for Arduino and motors).
Interior Design
To access the internal components, simply pull off one of the outer wheel covers, unscrew the wheel, and slide out the interior wooden frame from the side without taking apart the entire bot. The wooden frame is designed to hold the internal components in a tight arrangement to save space and preserve B-Bot's small size. As B-Bot makes its flips and turns, all the electronic components remain securely in place.
