The Chassis for Robot from 5" RRC04A is a Chassis from Acrylic of 1/8" that provides a base for our 42x19mm gear motors, brackets and wheels. The Chassis of the Robot has many mounting holes that allow you to mount a variety of components on it. With a diameter of just five inches, this Chassis made of Acrylic is great for building robots capable of navigating tight spaces.

This Robot Kit does not need welds or cables to mount it, you will only need one screw.
Bit:Bot can be used by children and adults and this Kit allows you to explore and encode Micro:Bit using one of the available languages (all features are not supported in all languages).

An 3WD Car Kit with Arduino Uno R3. Ideal for those who want to develop a remote-controlled robot car, line follower, fire truck, etc.

The RoverC is a programmable omnidirectional mobile robot base compatible with the M5StickC and can be started with the insertion of the M5StickC. The main controller of the base is the microcontroller stm32f030f4. The base comes with N20 worm gear motors, which are directly driven by a four-channel motor driver. These motors are connected to the mechanum wheels, which can move in all directions. In addition, two Grove-compatible I2C ports are provided to facilitate expansion to other modules.
