Robot Power Hydra Triple Channel R/C H-Bridge Motor Controller 6.5A, 6-28V
Offers fully reversible H-bridge design
Supports 6.5A continuous current per channel
Includes failsafe to shut off on signal loss
Features LED indicators for status and direction
Mixes channels for throttle and steering control
The Robot Power Hydra Triple Channel R/C H-Bridge Motor Controller 6.5A, 6-28V is a compact, high-performance speed controller designed for small robotic applications and various electrical loads. It is particularly suitable for ant and beetle-weight combat robots, R2D2 replicas, sumo robots, and other small robots such as firefighting robots, maze solvers, and carpet rovers. Additionally, it can drive pneumatic valves, solenoids, relays, and thermoelectric coolers, offering a versatile solution for diverse control needs.
This motor controller features a fully reversible H-bridge design, providing equal power handling in both directions across all three channels. It supports a continuous current of 6.5A, with a peak of 8A per channel, and operates within a battery voltage range of 6.0V to 28V. The device includes full current limiting and over-temperature protection, ensuring robust performance and safeguarding motors and batteries from short circuits.
The Hydra offers flexibility with its control options, allowing two channels to be mixed for throttle and steering or controlled separately, making it ideal for skid steer vehicles and robots. It includes limit switch inputs to control motion direction, indicator LEDs for motor speed and direction, and a status LED for operational status and error conditions. The controller also features a receiver battery eliminator circuit, a failsafe mechanism to shut off motors if the R/C signal is lost, and a calibration function to match the unit to the radio signal range.
Note: Ensure proper handling to avoid exposure to extreme temperatures or electrical short circuits.

A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
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.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
