Intelligent robots have several kinds of internal & external information sensors, such as vision, hearing, touch and smell. In addition to receptors, it also has effectors to react to surrounding environment. The effector is generally recognized as muscle or self-stepping motor, which makes hands, feet, nose, tentacles move. That’s to say, an intelligent robot must have at least three elements: sensory elements, reaction elements, and thinking elements.
Miniature robot servo motor is a low-power micro gear motor that can be used for the transmission system of intelligent robot. The main transmission structure consists of drive motor, gearhead(reducer). As for drive motor, brush DC motor , BLDC motor, coreless motor, stepper motor, servo motor can be used as the driving source. As for gearhead, planetary gearhead, cylindrical gearhead, general gearhead and worm gearhead can be used as reducer. Different gear motors can be used for different types of miniature robot. Parameter customization is usually adopted, such as output power, voltage, reduction ratio, output torque, output speed, noise, transmission precision etc.

Project Name: Gear Motor for Wheeled Robot
Project Description: Intelligent robots can act according to pre-programmed procedures or guidelines formulated by artificial intelligence technology. Mature intelligent robots can replace human work, such as production, construction, or dangerous work. The robot can be divided into wheel type, leg type, crawler type, snake type and compound type according to the movement mode. Among them, wheeled mobile robots accounts for a relatively large portion in the field of autonomous mobile robots. They have the characteristics of fast movement and simple control, and are widely used in automatic palletizing production lines and unmanned vehicles.
Technical Difficulties: One is the poor ability of the wheeled mobile robot to avoid obstacles when turning, and the second is the poor climbing ability, which limits application of this dc motor robot.
Solution: The driving part of wheeled mobile robot adopts a DC motor and a 38mm planetary gearhead, which are installed antisymmetrically. This method can make the wheel set coaxial and provide greater power (generally the size and power of motor are proportional to a certain ratio). So that it can reduce the stress point on the output shaft of the reducer, greatly shorten the wheelbase, and save space, making the robot compact.
