Best Szdoit in 2026

【Unassembled Tank Chassis】: Tank chassis is UNASSEMBLED when you received, which can aims to learn the mechanical structure. It is different from car chassis, which has the track and wheels. By this way, tank chassis can move smoothly in the complex environment, like grassland, sand, and and many little stone. If the car, will be easy to rollover. But the tank chassis has much more width wheel, so can easily pass these cases.

【Necessary for This Car】: Robot technology is difficult. It covers robotic mechanics structure, software, electronic hardware. So, it is necessary to learn the robot for a long time. By using this car robot frame, you will learn the assemble, controller, and code program.

【Code Programming】: When you get this car chassis, you should learn more to let the car move. E.g., you can use arduino controller board and many sensors to make some projects, like obstacle avoidance, tracing, automatic driving, AI learning.

【What You Get】: You will get this 3wd metal smart robot car chassis, which includes 3pcs omni wheels, 3pcs dc encoder high toque motor, 3pcs metal motor bracket, 3pcs metal couplings, 2 metal panel, and a set of screw kit. Please assemble it with patience.

【Solid Structure】: This 3wd robot car chassis has 2-layer metal panel being very solid and strong. The load weight is about 3-5kg. And the 58mm omni wheel is tenacious and wearable. 2-layer design would accommodate many electronics.

【High Torque DC Motor】: Motor is the core for the robot tank car chassis. 3pcs high torque encoder DC motor is used for this robot smart car chassis. One can get the speed feedback by the Arduino UNO R3 / Raspberry pie / Micro-bit programming.

【What You Get】When you order, you will get: 1set of metal frame, 4pcs diameter =97mm mecanum wheels, 4pcs 37 DC encoder motors, and screw kit. You will have to assemble it, it is not easy, just put the robot parts by this Amazon link product. Then, use screw to fix it.

【AGV Function】AGV now is very popular in the warehouse to carry the goods. By this robot chassis based on the mecanum omni-directional wheels,together with 4pcs encoder motor, you will have use the electronics controller to control the smart car chassis move. It is another choice for the AGV function realization, but with low cost price.

【Robot Learning】This mecanum wheel robot chassis kit belongs to the robotics. You can learn how to assemble it, the robotic structure, the model, the function, then you can design or improve the robot. Specially, you can learn the controllers, like Arduino uno R3, raspberry pie, 51 MCU

【Learn Robotics】: When you learn the robotics, embedded system, RoS system, this chassis platform model will be a good help for you. You can learn STM32, Arduino, Raspberry pie, and also robot assemble, code programming. Also, you can learn the robotic element unite, like dc encoder motor, caterpillar, shock suspension system, bearing, load, wheel. and know the assembling ability.

【Variable-Length Track】: The length of the plastic track can be changed from a very small hole, as shown in the pictures in the description or main pictures. Since this car chassis has many assembling ways, and thus, the length would be different along with the different assembling ways. So, we will provide the longest (or enough) tracks for the suitable robot chassis assembling.

【SOLID but CHEAP】This robot tank chassis is NOT ASSEMBLED, which can let you learn the mechanical structure. This is ONLY the robot chassis, NO any controller. This metal robot tank car chassis is made by ourselves factory, so we have the price advantage. The car chassis is metal, and the bearing wheels and driving wheels are premium engineering plastics, together with the track (the length can be adjusted.). Metal frame lets the structure solid.

【A Great Helper for Learning】This is ONLY the robot car chassis kit, NOT inlcuding any controller. But this tracked vehicle is designed for many types controllers, e.g., Arduino uno R3, Raspberry pi, Nodemcu, Microbit and other controller development board. So, it is easy to DTY a remote control robotic platform, and thus you can learn Arduino, Raspberry pi program, robotics program, and it is the best choice for the steam education.

【AI Leaning】 Driverless is now very popular. Based on this car chassis TP101, you can know many AI knowledge, such as machine learning, RoS, deep learning, Reinforcement learning, and other robotics knowledge. When you have a good algorithm, you can realize on any controller.It is a good choice for you to realize the AI learning algorithm function.
