Description

 

WHEELTEC 4WD Basic Version Robot Car Assembled Robotic Car for Maker Education Research Competition

4WD Basic Version:
- Chassis, STM32 main control board, battery and charger are included.
- Reserve the installation conditions of LubanCat 1S, Lidar, RGB camera, etc., but these accessories are not included in the package.
- Communication with the car can be realized through your remote control or through the serial port.

Features:
4WD chassis
- Because the three-point surface is formed, the four-wheel drive chassis will have poor performance if it does not add a suspension system.  However, with special-shaped installation, the installation position of the two wheels on one side is very close, similar to one wheel, and the problem of uneven ground wheels hanging can be solved without suspension. Through innovation, we have been able to meet our customers' demands for high quality and low price, made the motors installed displaced and reduced the size of the product.
- Based on our theoretical analysis and practical verification, the special-mounted four-wheel drive chassis can have the same motion effect as the solid and conventional four-wheel drive chassis, which fully meets the requirements of ROS robot development.

Simple and easy-to-use industrial design
Scientific research robots need to meet the requirements of beautiful appearance and ease of use. The bottom of the car uses a closed sheet metal design, which better protects the battery (with relatively low development frequency and relatively large power), motor, etc., and eliminates potential safety hazards. The upper part uses a streamlined bracket for secondary development and ROS expansion, which makes it easy to debug and plug.

GMR high-precision encoder
- The newly upgraded 500-wire AB-phase GMR high-precision encoder has more than 38 times the accuracy of Hall encoder (used by similar products on the market). Equipped with GMR high-precision encoder, the performance of the car is excellent when navigating at low speeds.
- Equipped with four high-power motors, the movement effect and load capacity of the car chassis are outstanding.
