SnappyXO Design is a design-driven educational robotics framework. It contains a hardware robot kit and a motion synthesis app. Users can first synthesize the motion using the MotionGen app and then put the structure together using the hardware kit.

SnappyXO can be used to make robust multi-legged robots as well.
These projects were done by freshman students at Stony Brook University.
What students and teachers think of SnappyXO
Working with the SnappyXO kit during my first semester in college made me feel like an actual engineer. The kit allowed for a combination of two major characteristics of engineers: the imagination needed to think of different structures and designs and the determination and willpower needed when the pieces did not fit in the desired ways.
The snappyXO offers a cost effective solution to students without limiting their creative freedom.
Unlike other robotic kits that are out there in the market, the SnappyXO kit does not involve nuts, bolts and screws, thus allowing me to create different mechanical structures with simple and quick construction. Even though joints and linkages are attached by plastic clips, the structure is still very sturdy.
I really enjoyed MEC 101 last semester. Thank you prof. Purwar.
The SnappyXO kit is a limited and finite kit that you can apply your unlimited and infinite imagination on it. It is an innovation in engineering education and capable of leading students to the right path in mechanical engineering with joy and fun. Several different parts can make up numerous configurations that fit your design, and the possibility fully depends on your creativity!

Open Source Electronics
One of the greatest strengths of the SnappyXO robot kit is that it is designed to work with low-cost sensors, actuators, and open-source electronic prototyping boards, such as the Arduino and Raspberry Pi. The Arduino is a super easy to learn rapid prototyping board used by both amateurs and professionals. The ease of use of the Arduino makes programming the SnappyXO fun and educational.

Easy to Assemble
This two-wheel drive robot does not require any special tools and only takes 90 seconds to assemble. SnappyXO is designed to be easy.
Multiple Material Options
The kit is compatible with durable yet inexpensive acrylic, nice looking wood, and strong Delrin. This makes the kit more versatile. All three materials have its advantages and disadvantages. Delrin is typically used for joints and clips that will experience higher stresses than other parts of the robot, while acrylic is usually used for the body or the skeleton. Wood can be used in the body instead of acrylic to give the robot a premium feel and look. Delrin and acrylic allows for unique geometrical features, such as slots, shapes, holes, and clips that mate with each other.
Other Key Features
The kit consists of a suite of basic planar, laser-cut pieces that can be snapped together to create the robot and machine design structure encompassing chassis, sensors, and actuator mounts.
The novelty of the kit is in designing the compliance in a wide variety of materials, such as Acrylic and Delrin by creating unique geometrical features, such as slots, shapes, holes, and clips.
Easy to Produce
Only a laser cutter and compatible materials, such as Delrin, Acrylic, or wood are needed to produce SnappyXO parts.
Various joints and parts including different gear sizes allow the kit to be highly versatile for making robots and structures.
The kit does not require any special tools to assemble the robots and structures and the hardware created works with a range of sensors and actuators available in the market.
Since I began to teach Freshman Design Innovation class at Stony Brook University, which culminates in an extensive robot design and building project, I had always desired to provide a simple, intuitive, and low-cost robotics kit to all the students. Additionally, I wanted something that would work with the off-the-shelf sensors, actuators, and microcontrollers. A kit can feel limiting, but with the right approach, it could be turned into a general platform on which students could exercise their creativity and inventiveness with custom-designed parts. Out of that desire was born, SnappyXO, an all laser-cut, modular robotics kit, which is completely designed and manufactured in the Computer-Design and Innovation lab. Seeing students’ excitement and happiness when their robots performed well in the final project demonstrations was very satisfying. This kit is owed to more than 600 students have used it in my classes, workshops, maker faire, and demonstrations and provided great feedback, which helped improve its design.
