Studica provides a robotics building system based around aluminum channels, gears, precision shafts, and bearings. With our multipurpose hole pattern, all components can be easily connected and are compatible with multiple building systems. This comprehensive building system offers a wide variety of hardware, electronics, motion, and structural components. There is also very little need for a machine shop because the structural components are all designed to work easily together. Here are some of the items we have to offer:

• The VMX Robotics Controller allows you to program in C++, Java, Python, LabVIEW and ROS; making it a great teaching tool for coding and allowing students to prepare for competitions. It can also be used as a Vision/Motion Controller.
• The NavX2 MXP Robotics Navigation Sensor and the NavX2 Micro 9-axis Inertial/Magnetic Sensor.
• A slim 100mm mecanum wheel can reduce the width of the robot while allowing you to make the base wider.
• Our Intake Hub Kit is designed for creating intake systems.
• There are 288mm and 384mm Low Profile Slide Rail that are prefect for elevator mechanisms.
• Three models of Servo Linear Actuators.
• Hundreds of mechanical components that all work easily together.
