Story

I'm incredibly pleased to introduce Mini Pupper! Our consumer-friendly, low-cost, open-source, self-navigating robot for education. Even though this is a fully-featured quadruped robot, we are targeting this robot to meet our customers' number one request -- a platform to learn and study the unlimited potential of quadruped robots. And that's what this product is targeted for. We hope it will be the number one education platform for quadruped robotics globally. Beginning last year, we shipped many Stanford Pupper units worldwide. After such global success with Pupper, we took to heart all the feedback from this endeavor. What do our customers want in our products? What kind of products do they like? After more than 11 months pursuing these requests, we would like to show you what we came up with. Mini Pupper!


Our Mini Pupper servo is a custom servo to meet the requirements of our new Pupper! Compact, Durable, Unique. To run the Mini Pupper organically and smoothly, high torque & high-fidelity servos were required. We tested many servos on the market and have not found any 9g servo up to the task. After too many Q.C issues we finally gave up on off-the-shelf hobbyist servos, the last thing we want is for our intelligent customers to be let down by poor quality servos. So, we spent several months optimizing and configuring a servo that would work for our project, including tuning the servo parameters ourselves! It is now named Mini Pupper servo.


You can use our Mini Pupper to explore many gait performances, such as Trot (diagonal pairs), Pace (lateral pairs), and the Bound (front and rear pairs). We’re confident our Mini Pupper Servos will outperform any servo for the balance of performance and price. The mechanical design is simple, stable, and beautiful. You can find many prototype quadruped robots, but few can go to market because of their complex design! Difficult to assemble, lack stability while trotting, and require unpredictable costly repairs. For the average engineering student or extremely curious individual these quadrupeds will work, however, they are not suitable for mass production... The Mini Pupper addresses these issues by creating a professional robot designed specifically for mass production, driving unit costs low enough for even low-budget schools to acquire the robots for learning.


Driving innovation for the next generation of robotics enthusiasts. Unlike other 3D printed robots, we use metal threaded inserts to ensure customers can disassemble and reassemble easily while making repairs after extensive use. All parts are secured with quality fasteners ensuring great fit and function as well as durability of the unit. Cleaner builds were achieved by customizing the servo cable length and integrating the IMU into our carry board to reduce the wiring necessary and have an overall clean setup in the body of Mini Pupper. No lose wires! Unlike other enthusiast-made kits, our Mini Pupper does not require the user to plug or unplug wires to power the unit on and off. A simple flick of a switch is all you need! The Mini Pupper battery is charged without the need to remove the battery from the robot, onboard voltmeters will sound alarm and worn you that your unit needs energy. Mini Puppers design was based on the feedback we received from our existing customers. Because of this we now have a quadruped robot easier to setup and play with than any other robot on the market. Customers with minimal or no experience will be able to use this robot.
