If your SuperDroid robot is down and out of warranty, this page is where you start. Pay the diagnostic fee for your platform size, and we handle round-trip freight and a full evaluation before any major repair work begins.
The amount you pay here covers shipping both ways and diagnosis only. Unless the fix is minor, we will send you a separate repair quote for parts and labor after we have the unit on the bench. You approve that quote before we proceed.
How the repair process works
Return for diagnosis. We evaluate the robot and OCU and confirm the root cause before any major work. Once we receive payment for freight to and from our facility, we schedule a pickup of the robot and OCU.
Quote for approval. We send you a quote for the repair of the robot and OCU, including estimated turnaround, before we proceed.
Repair and return. The unit is repaired, tested, and shipped back to you.
On older platforms, repairs often involve freight both ways, legacy parts, and extended labor. All in, repairs of this type commonly reach $10,000 or more, and on units that age we sometimes find additional issues once we are inside. The diagnostic fee does not cap or include those costs.

Itemized repair quote before any major work begins
On platforms like these, total repair costs commonly exceed $10,000 when legacy parts, arm rebuilds, and additional issues found during teardown are included. That work is always quoted separately.
Before you pay
Drain batteries per your operator manual before packing. Include the full OCU case, chargers, and any arm tooling that shipped with the unit. We will coordinate liftgate freight pickup after payment clears.
Important: The diagnostic fee is not a flat repair price. It pays for round-trip shipping and our time to find out what is wrong. If the repair is minor, we may complete it during diagnosis at no extra charge. For anything beyond that, you will receive a quote and decide whether to proceed. Questions before paying? Submit a support request or see our repairs and returns page for warranty RMAs.
FAQs
What does the diagnostic fee actually pay for?
Freight to our shop and back, plus the bench time to evaluate your robot and OCU. We test the systems, identify the root cause, and report what it will take to fix. The fee does not include replacement parts or repair labor unless the fix is minor enough to handle on the spot.
How do I know which tier to choose?
Pick the tier that lists your robot model or the closest match. GPK-32 and MLT-JR are Tier 1 ($500). PTW-42 and MLT-family mid-size robots are Tier 2 ($1,800). Bulldog, Bloodhound, and Mastiff are Tier 3 ($4,800). If your unit does not fit neatly into a tier, contact us before paying so we can confirm the right freight class.
Do I need to send the OCU?
Yes. Ship the operator control unit with the robot. Drive, video, and arm problems often trace to the link between the OCU and the chassis, and we need both to run a complete diagnosis.
What happens after I pay?
Our team contacts you to schedule freight pickup. Once the robot and OCU arrive, we evaluate the unit and send findings along with a repair quote if work is needed. Nothing beyond minor fixes starts until you approve the quote.
What if I decline the repair quote?
We return the unit as-is. The diagnostic fee already covered round-trip freight and evaluation, so there is no additional shipping charge for sending it back without repair. If you want us to scrap or part-out the unit instead, let us know when we send the quote.
How long does diagnosis take?
Most units are evaluated within 5–10 business days of arrival, depending on shop load and platform complexity. Large tactical robots with arms and multiple payloads can take longer. We will give you a realistic timeline when the unit is checked in.
Is this the same as a warranty repair?
No. This page is for out-of-warranty service where you prepay freight and diagnosis. If your robot is still under warranty, use our Repairs + Returns form to request an RMA instead of paying here.
Can additional problems change the repair cost?
Yes. On older platforms we sometimes find issues beyond the original complaint once the unit is opened up. If that happens, we stop, document what we found, and send an updated quote before doing any additional work.
Can I ship the robot myself instead of scheduling pickup?
Contact us first. The tier pricing assumes we arrange freight both ways. If you prefer to ship on your own account, we can discuss whether that changes the fee. You will still need to pay for diagnosis before we begin evaluation.
What payment methods do you accept?
When you click Pay Diagnostic Fee, you go through a secure Stripe checkout. You will enter your shipping address, phone number, and a short description of the issue with your robot. After payment clears, we send a receipt and follow up to schedule pickup.
