Wasp User Manual

Thank you for your purchase of the Robot Power Wasp™ motor control. This manual

explains the features and functions of the Wasp along with some tips for successful

application. Before using your Wasp you must read and agree to the disclaimer printed at the

end of this document. If you don’t agree please return your unused Wasp to Robot Power for

a refund.

The Robot Power Wasp is a low-cost, easy to connect power amplifier designed to work with

DC motors, lights, solenoids and other low-voltage DC loads. The Wasp is configured as a

single H-bridge circuit and allows bi-directional control of a single motor or other load. While

designed for permanent magnet brushed DC motors; the Wasp is suitable for a wide range of

DC loads as long as they are within the current and voltage envelope of the device.

glow solid when a good RC signal is detected. If the signal is lost or goes out of the legal range the status LED will blink. See below for instructions on using the limit switch inputs and for configuring the internal voltage regulator and BEC for your setup. LED Indicators The Wasp has two LEDs used for visual indication of the state of the unit. The Status LED is green and shows the status of the RC signal to the unit.
PAGE 4
Calibration Some receivers and radio setups have different center and endpoints than the factory configuration shipped in a new Wasp. To match the Wasp to your actual RC range a calibration sequence can be run. After calibration the new values are stored in the Wasp CPU and are retained permanently. Following is the calibration sequence: 1) Power on the Wasp either with the main battery or through the RC cable. The status LED should be solid showing the Wasp is locked to the input signal.

Battery Inputs: The Wasp requires an external battery connected to the battery positive and negative terminals. The positive terminal is marked with “++++” on the silk screen of the unit. The polarity of the battery input must be respected. Reversing the battery connections can damage the unit. The Wasp does not require external filtering or voltage regulation. It may be used directly with a 6V-28V battery or other voltage source.
PAGE 6
The internal voltage regulator of the Wasp is a National Semi LM2940IMP-5.0 regulator. This is a linear type regulator and generates significant heat when the difference between the battery voltage and the 5.0V regulated output voltage is large. If the voltage regulator gets too hot it will shut off to prevent damage. This disables the Wasp since the internal CPU uses the output of the regulator. The Wasp has been tested up to 21V input without overloading the regulator.
