Guidelines for Building Team FREDNET Lunar Rovers
From TeamFrednetWiki
This is the rover interface specification document.
General
The GLXP Requirements specify that we be able to traverse a distance of 500 meters. Implied in this requirement is a method to measure the distance traveled.
The GLXP also specifies that the rover be able to transmit two mooncasts, including at least 8 minutes each to be broadcast as both Near Real Time and as High Definition video. The rover will perform this work in wireless communication with the lander.

Build a WRV1 by your own
Joerg has developed a series of blueprints with all the technical information in order to build the WRV1 lunar rover.

Build a PicoRover by your own
PicoRover is a Ball based open hardware design. In this section you will see how easy it is to build your own PicoRover with commond materials. See our live demonstrations or on-demand videos how we build this lunar robot.
CONSTRUCTION PROCEDURE
PicoRover SHIELD area
| Buy 2 bulbs of 10cm diameter. It is recommended to use a lathe to hold the bulb but other method can be used. Mark the equator and the pole with permanent marker. Cover the bulb with a very thin mesh. |  |
| Apply polyesther resin to all the surface and fiber glass for reinforcements. You can put a layer of polyurethane for increase the rover diameter. Glue a thin layer of aluminum sheet. Make sure don't let air or bubbles in between. Cut half bulb in the equator using Dremel(R) or equivalen tool. |  |
| Remove from the hold. Drill the pole and tight a roller. Protect the roller races and the bolt. Cover the inside surface with polyesther and make fiber glass reinforcement in the exterior roller race. |  |
| Take other bulb of 10cm diameter. It is recommended to use a lathe to hold the bulb but other method can be used. Mark the equator and the window parallel. Protect the window with a thin layer of PLASTELINA(R) or similar. |  |
| Apply polyesther resin to all the surface and fiber glass for reinforcements. You can put a layer of polyurethane for increase the rover diameter. Glue a thin layer of aluminum sheet. Make sure don't let air or bubbles in between. Cut half bulb in the equator using Dremel(R) or equivalen tool. |  |
| Cut a shape of aluminum 5 mm wide and drill 0.8mm each 3mm each side. |  |
| Buy a train rail and blend as a ring. Make teeths inside. |  |
| To close the PicoRover we need flanges. We use these flanges to stick hairs. Use a cast to make a flange. Put the PicoRover half inside. You need a shape for the hair. Put the hair inside the flange. Drill 6 holes to close the PicoRover by 6 micro-bolds. |  |

PicoRover CORE area
To be done
PicoRover PAYLOAD area
The PicoRover is empty in the center. This place is dedicated to an Elphel Camera for the GLXP but you can install your own payload there. The window is near from this area, also radio antennas are suitables to be installed there.
The payload is limited in mass due to the thrust performances. It is about the half of the total mass but in addition, for distribution of mass it is very sensitive.
