Propeller QuadRover Robot (#28195) or "QUADROVER"
The QUADROVER uses a Honda 2.5 HP 4-stroke engine to activate an hydraulic power system managed
by the Propeller Control Board for the ultimate in customizable robots. There are twelve 5-volt-tolerant
general-purpose Propeller I/O pins available, four free N-channel switches, and five available servo ports.
The Propeller Control Board includes sockets for GPS, compass, and 3-axis accelerometer sensors (sold
separately). The QuadRover is a heavy-duty robotics test-bed that is presently intended for research and
development, including custom user-written programs and control systems.

Please observe the following precautions: Parallax Inc. will issue changes to this manual to update its accuracy and apprise the customer of new procedures and design changes. It is the customer’s responsibility to maintain an updated operating manual. -
Page 4: Technical Specifications
QUADROVER will be entirely at the customer’s own risk. Parallax is available to answer technical questions relative to the QUADROVER but will not advise as to loading of the QUADROVER chassis with customer modifications. 1.2. Technical Specifications Dimensions: 29 x 19 x 23 in. -
Page 5: Hydraulic System
Hydraulic oil pressure in the QUADROVER varies as the viscosity of the oil changes. Hot oil (above 165 °F) could cause pump cavitations, excessive noise and wear to the motors. While the rating of the hydraulic system is 2,800 PSI (continuous) and the pump is capable of developing pressure to 2,300 PSI, this is generally not possible with the engine supplied in the QUADROVER. -

(no electrical connection) to show approximate temperature of the hydraulic oil. 3.2. Propeller Control Board Electronics Since the various controls for the QUADROVER would be difficult to control manually, a Propeller Control Board (Parallax stock #28205) is included to properly operate the QUADROVER. Before programming the Propeller Control Board, download the example code from the QUADROVER product page at www.parallax.com and carefully read through and follow the included documentation. -
Page 7: Tachometer Input
The Propeller Control Board includes a tachometer input that can be connected to the magneto of an engine to determine its rotation speed. To be functional, the tachometer input requires the Propeller Control Board’s electrical ground to be connected to the QUADROVER chassis ground. See the precautions in section 3.3 before connecting the tachometer. -

Page 10: Setup Instructions
When connecting the charged battery, be sure that the fuse casing and leads do not contact the drive belt. 3. Mount the QUADROVER on a stable, raised platform so that the wheels are not in contact with anything. 4. Read the Honda Engine Manual, and follow those directions for adding oil to the engine. The oil cap is shown in the picture below. - Page 11 Tighten the set screw. 7. Add hydraulic oil to the hydraulic reservoir and bleed all air out of the hydraulic lines: a. The QUADROVER must still be mounted on a stable, raised platform such that the wheels do not contact anything.
- Page 12 Reinstall the screw and o-ring and tighten by hand until snug; do not over-tighten. m. Replace the pressure relief valve. n. With the QUADROVER still firmly mounted on its platform, follow the instructions in the Honda Engine manual to start the engine. Run the engine for a few minutes, let it cool off, then check the hydraulic oil level.
- Page 13 Using the mounting screws and nylon washers, in the arrangement shown, screw the right front and back sides of the roll-cage into the QuadRover chassis. d. Attach the metal washer and locking nuts to the right front and back sides of the roll- cage, as shown.

2. If the flow-cutoff valve has been used to disengage hydraulic flow to one side of the QUADROVER, brakes can be applied to that side, but should be applied gradually. Sudden braking of a single side of the QUADROVER while it is in motion may cause the QUADROVER to skid and lose control. -

4. Increase gas throttle servo proportional to desired speed. Turning while 1. Engage the cutoff solenoid on the side of the QUADROVER that it will be driving turning toward. 2. Gradually engage the brake, located on the same side of the QUADROVER, proportional to the desired turn rate.
