3WD 100mm Omni-Directional Triangle Mobile Robot Kit
Description
- Economical platform of 3WD omni-wheel
- Easy to install
- Programmable Arduino microcontroller board
- Arduino 328 Controller
- Comes assembled with only wheels not attached
The 3WD 100mm Omni-Directional Triangle Mobile Robot Kit is based on a 3WD omni-wheel chaise. It could move in any direction by changing the velocity and direction of each wheels without changing its orientation. This robot help you get acquainted with the omni-wheel platform, embedded system. Its aluminum alloy body and pre-drilled hole for screws make it convenient for you to add components as you like.
Omni-directional wheels are unique as they are able to roll freely in two directions. It can either roll like a normal wheel or roll laterally using the wheels along its circumference. Omni-direction wheels allow a robot to convert from a non-holonomic to a holonomic robot. A non-holonomic robot that uses normal wheels has only 2 out of 3 controllable degrees of freedom which are, moving forward/backwards and rotation. Not being able to move side ways makes a robot slower and less efficient in reaching its given goal. The holonomic omni-directional wheels are able to overcome this problem, as it is a highly maneuverable. Unlike normal non-holonomic robot, the holonomic omni-directional robot can move in an arbitrary direction continuously without changing the direction of the wheels. It can move back and forth, sideways and rotates at the same position.
Features:
- Encode motors
- Pre-drilled holes and spare space make it expandable
Arduino 328 microcontroller board
It is a microcontroller board based on the Arduino 168. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

Arduino IO Expansion
Nexus Robot provides the ultimate functional expansion for Arduino IO Expansion V1.2 and gives you extra ease to connect device such as sensors, servo and RS485 device. This sensor expansion board is able to easily connect a number of commonly used sensors.

- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A €100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
- Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
- Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
- Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.

- Professional & Specialized Equipment — See the Professional & Specialized Equipment Warranty page and Professional & Institutional Buyers (B2B) section in the Terms & Conditions.
* European consumers retain their statutory Right of Withdrawal on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Withdrawal, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
