The kit is compatible with various development boards. Using the kit, you can make your own robot smart car. This omnidirectional wheel is very flexible, It can move laterally without turning, and it can adapt to complex terrain. There are 4 such new wheels to combine, which can realize all-around movement function more flexibly and conveniently. The chassis is made of aluminum alloy, which is durable.
Tired of making 3-point turns with your robot
Standard differential drive robots are great, but they lack agility in tight spaces. If you are building a warehouse bot, a surveillance rover, or a ROS-based mapping robot, you need the ability to move sideways, diagonally, and rotate in place without friction. This Aluminum Mecanum Wheel Robot Car Chassis Kit (Double Deck) is the robust, omnidirectional foundation your advanced robotics projects have been waiting for.
Built Like a Tank, Moves Like a Dancer Unlike flimsy acrylic chassis kits that crack under load, this platform is constructed from high-strength aluminum alloy. The "Double Deck" design provides two distinct layers: a lower deck for your heavy motors and battery, and an upper deck dedicated to your delicate electronics like Raspberry Pi, LiDAR, or Jetson Nano. We know that shipping metal kits can be risky, which is why this unit ships with Probots Secure-Transit packaging, ensuring every plate arrives straight and every screw hole aligns perfectly, ready for assembly.

- Aluminum Alloy Body: Anodized finish resists corrosion and provides a rigid, wobble-free base for sensors.
- High-Payload Capacity: Rigid frame supports heavier batteries and multiple sensors without flexing.
- Probots Lab Verified: Our engineering team has tested this chassis configuration to ensure the included motors provide sufficient torque for smooth strafing on hard surfaces.
Applications
- Warehouse Logistics Prototypes: Simulate AGV (Automated Guided Vehicle) paths.
- ROS Education: Ideal "TurtleBot" alternative for university labs.
- Competition Robotics: High agility for "Robo-Soccer" or maze solving.
- Surveillance: Smooth turning for stable camera feeds.
Virtual Technician & Wiring Guide ⚠️
- Critical Warning: DO NOT drive these motors directly from your Arduino or Raspberry Pi pins. You MUST use a motor driver.
Note: You will need either a 4-Channel Motor Driver Shield or 2x L298N Drivers to control all 4 wheels independently. Independent control is mandatory for strafing.
Required Additional Items (Not Included):
- Microcontroller (Arduino Uno/Mega, ESP32, Raspberry Pi)
- Motor Drivers (e.g., 2x L298N or 1x L293D Shield)
- Power Supply (18650 Battery Holder and Batteries)
- Jumper Wires
Package Includes:
- 2x Aluminum Alloy Chassis Plates (Top and Bottom)
- 4x Mecanum Wheels (2x Left-handed, 2x Right-handed)
- 4x Dual Shaft DC Gear Motors
- Fasteners, Spacers
Frequently Asked Questions (Technical FAQs)
-
What is the difference between this and a normal car chassis?
This uses Mecanum wheels, allowing it to move sideways (strafe) and diagonally, which standard wheels cannot do. -
Does this kit come assembled?
No, it is a DIY kit. You will need to assemble the plates, mount motors, and attach wheels using the included screws. -
Can I control this with an Arduino Uno?
Yes, but the Uno cannot power the motors directly. You need a motor driver shield or module. -
How many motor drivers do I need?
To use the Mecanum features fully, you need to control 4 motors independently. We recommend using two L298N drivers or a dedicated 4-channel motor shield. -
What is the payload capacity?
It can carry approximately 1kg to 1.5kg effectively on flat surfaces. -
Are the motors included?
Yes, 4 DC gear motors are included in the box. -
Do the wheels have bearings?
These are standard kit-grade Mecanum wheels; the rollers spin on steel pins. They are durable for hobby use but not industrial sealed bearings. -
Can this chassis work on carpet?
Mecanum wheels struggle on thick carpet due to friction interfering with the roller movement. Hard floors or thin carpet work best. -
Is there a code library for Mecanum wheels?
Yes, there are many open-source Arduino libraries available. Search for "Mecanum Drive" or "Holonomic Drive" libraries. -
What voltage should I run the motors at?
They run best between 6V and 9V. A 2-cell LiPo (7.4V) is the sweet spot. -
Does it include a battery holder?
Yes, a standard AA battery holder is typically included, but we recommend upgrading to rechargeable Li-ion cells. -
Can I mount a Raspberry Pi?
Yes, the aluminum plates have various slots that can accommodate Pi standoffs, though you might need to drill one or two holes for specific alignments. -
Is the chassis pre-drilled for sensors?
Yes, there are slots suitable for mounting ultrasonic sensors, servos, and line followers. -
What is the material of the wheels?
The wheel hub is plastic, and the rollers are rubberized for traction. -
How fast does it go?
At 6V, the speed is approximately 0.6 m/s, which is a brisk walking pace for a robot. -
Why is my robot not moving sideways?
Ensure your wheels are mounted correctly. The rollers on top should form an 'X' shape when looking down at the chassis. If they form an 'O', they are swapped. -
Can I use this for a line follower?
Yes, but Mecanum wheels are overkill for line following. Standard wheels track straighter. -
Does it include a remote control?
No, this is a chassis kit only. You need to add your own Bluetooth, WiFi, or RF receiver. -
Are spare parts available?
We stock spare DC motors and individual Mecanum wheels if you need replacements. -
Is this waterproof?
No, the motors and chassis are not waterproof.
