Price Match Guarantee

We match the lowest online price on the products we sell — and if you find a lower price on a product listed over $2,000, we will beat it by $50. Purchase from our store first, then send proof of the lower price (a screenshot, invoice, or email) to support@roboticsselect.com and we will refund the difference.

A few requirements: the competitor must be an authorized online retailer of the product with the item in stock on their website, must be online-only (no retail location), and cannot be a discounter or auction site such as eBay or Overstock. The comparison includes the item price and shipping charges but excludes sales tax.

Rebates, buy-one-get-one offers, and special once-a-year promotions such as Black Friday and Cyber Monday are not eligible. Certain exceptions may apply.

Full Price Match Policy

Returns & Refunds

Cancel any time before your order ships for a full refund, free of charge. Custom and made-to-order products are put into production for your specific order, so all sales are final on those items.

You have 30 days from the date you receive an item to start a return — email support@roboticsselect.com or call (412) 415-7375. Products must be returned unopened and unused. Some brands set their own return terms, and the brand-specific policy on the product page overrides the general 30-day window; if the manufacturer will not permit a return, we cannot offer one.

Outright returns after shipment incur a 25% cancellation fee plus return shipping, and manufacturer restocking fees (usually around 20%) may also apply — return shipping costs are the customer's responsibility. Refunds go to your original payment method and are processed within 10 days of our receiving the returned product.

Inspect the package when it arrives: note any damage when signing for delivery and send photos to support@roboticsselect.com within 24 hours — freight damage claims are not valid after 24 hours.

Shipping & Delivery

Standard curbside delivery is always completely free. Most orders ship out within 1-5 business days, and delivery takes 5-8 business days once shipped (estimated delivery 6-13 business days). All shipping times are estimates and can vary by brand, especially for made-to-order items.

Orders ship fully tracked via USPS, UPS, or FedEx, and we email your tracking information within 24 hours of the order leaving the warehouse. If tracking hasn't arrived within six business days of ordering, contact support@roboticsselect.com.

Upgraded delivery options are also available: Threshold Shipping brings the item onto your porch or into a sheltered/garage area, and White Glove Delivery brings it into your room of choice, includes minor assembly, and removes all packaging.

We do not ship outside the USA, with limited exceptions — if checkout accepts your shipping address, we can deliver to it.

Financing Options

Split your purchase into 4 equal, biweekly payments at 0% APR with Shop Pay Installments — no hidden fees and no late fees. For larger orders, monthly installment plans may also be available, with rates from 0% APR or 10-36% APR depending on your purchase amount and eligibility.

Approval is fast and real-time: Shop Pay Installments is powered by Affirm and gives you a decision in seconds at checkout. Checking your eligibility is a soft credit check that does not affect your credit score, and while there are no late fees, partial or late payments may affect your eligibility to use the program in the future.

To qualify, you need a United States billing address and a U.S. mobile phone number that can receive SMS. Prefer PayPal? Choose PayPal Pay Later at checkout to split eligible purchases into interest-free installments (subject to PayPal approval).

Frequently Asked Questions

How does the C650 differ from the M750?

The C650 has 6 degrees of freedom (versus 7 on the M750), shorter reach at approximately 250 mm (9.8 inches), and lower-cost mechanics. Both share the same SDK and software ecosystem. Choose the C650 for teaching environments where a standard 6-DoF kinematics curriculum is more relevant. Choose the M750 for research that needs the redundant 7th joint for elbow positioning.

Is the C650 suitable for ROS-based learning?

Yes. ROS 1 Noetic and ROS 2 Humble are both supported. URDF files are provided for MoveIt motion-planning experiments and for Gazebo simulation. The arm is widely used in undergraduate ROS courses because the cost-per-unit allows a class to have one arm per student or per pair.

Does it come with a gripper or end-effector?

Yes, a parallel-jaw gripper is included in the base package. The same end-effector ecosystem as the M750 is supported (soft gripper, suction, custom 3D-printed tools). End-effector mounting is a standardized 4-pin connector and 4-bolt pattern.

What is the payload?

200 g rated payload at full extension. This covers small electronic components, light fasteners, candy, paper cups, and most educational manipulation objects. For heavier or more demanding tasks, step up to the myCobot Pro 600 or industrial arms.

How is repeatability and accuracy?

Approximately 0.5 mm (0.02 inches) repeatability under rated payload at moderate speed. Absolute accuracy depends on calibration; the factory-calibrated arm is typically within 1 to 2 mm (0.079 inches) of commanded Cartesian positions. For higher accuracy, end-of-arm vision feedback (visual servoing) brings final positioning to camera-pixel resolution.

Does it work with NVIDIA Isaac Sim?

Yes. URDF and MJCF files are provided for Isaac Sim, Gazebo, MuJoCo, and PyBullet. Sample reinforcement-learning training scripts are published on Elephant Robotics' GitHub. Sim-to-real transfer of grasping policies works reasonably well because the joint dynamics are simple.

Is the C650 safe for classroom use?

Yes with normal supervision. Joint torque is limited in firmware to prevent injury at full speed. The arm cannot apply enough force to break a finger but can pinch with the gripper. Standard classroom safety: keep loose clothing and hair away from joints, use the emergency stop button when starting new programs, and supervise younger students directly.

Can students do their own kinematics work or is it pre-programmed?

Both are options. Pre-built primitive functions (move_to, grasp, release) are available for quick demonstrations. Lower-level joint control through the SDK allows students to implement their own forward and inverse kinematics. Course materials from several universities are published online for instructors who want a starting point.

What warranty applies?

12-month manufacturer warranty on the arm and controller. End-effectors warranted 6 months. RoboticsSelect handles warranty service as the authorized dealer.
