The Robot Power Hydra is a small low-cost high-performance
triple channel H-bridge speed controller for small robots, and other electrical
loads. It is designed for ant and beetle weight combat robots, R2D2
replicas, sumo robots, and other small robots such as firefighting
robots, maze solvers and carpet rovers. The Hydra is also suitable to
drive pneumatic valves, solenoids, relays and thermoelectric coolers.
The Hydra is designed to pack the highest power handling
capability, flexibility of control and usability options into the
smallest package.
Features
- Size: 2.0" x
2.1" x .5"
- Weight: 28.0 grams
- Standard R/C pulse format
- 6.0V to 28V battery
voltage
- 6.5A continuous (8A peak)
current on each channel.
- Fully reversible H-bridge
design. Equal power handling in both directions on all three
channels.
- Full current limiting and
over temp limiting. This thing is nearly blow proof! Motors and
batteries are protected from dead short conditions.
- Two channels may be
either mixed (throttle/steering) or separately controlled. Ideal for
skid steer vehicles/robots.
- Limit switch inputs to
stop motion (AUX channel only) in one direction when closed. Motion
is allowed in the other direction.
- Indicator LED for speed
and direction of motor on each channel
- Status LED status
information and mode indications
- Receiver battery
eliminator circuit (BEC) standard - may be disabled. This can
provide up to 100 mA of current at 5V to
the RC receiver and other attached electronic circuits.
- Failsafe shuts off motors
if R/C signal is lost
- Calibrate function to
match unit to radio signal range. Settings retained in EEPROM
non-volatile storage.
- FLASH-based microcontroller
with upgradeable software via in-circuit programming header
- Ceramic oscillator
(crystal) for stable operation at all temperatures
- Capable of supporting I2C
or serial command streams. Serial not supported by stock R/C
software but user may replace the stock code if desired. Contact us
if you would like to discuss custom software for your application.
