You can improve your Arduino skills with Arduino training kits. Arduino is an open source electronics platform commonly used in robotics projects. Arduino training kits are aimed at improving Arduino skills by practical applications. In Arduino training kits category you can find sets which consist of materials to be used in Arduino based electronics or robotic projects.
Arduino training kits are based on Arduino microcontrollers. The reason for that is the ease of use provided by Arduino microcontrollers. Since these microcontrollers are easy to use most hobby robotic projects are based on these microcontrollers, too. The shields developed for Arduino microcontrollers are also easy to use products. Therefore Arduino platform is a good choice for robotic projects and having some knowledge about this platform is also a must for robot developers. The purpose of Arduino training kits is to help people who want to improve their Arduino skills for their robotic projects.
