This vehicle was chosen to understand how a Pixhawk could be used for wheeled platforms. We chose to use a Traxxas vehicle as they are very popular and it is a very strong brand in the RC community. The idea was to develop a platform that allows for easy control of wheeled UGVs with an autopilot.
3DR 10S Power Module
3DR 433MHz Telemetry Module (EU)
The assembly consists of a wooden frame on which all the autopilot parts were attached. Tests showed that a better vibration insulation should be used, especially for the Pixhawk and the Flow module.
:::warning It is HIGHLY RECOMMENDED to set the ESC in training mode (see Traxxas Stampede Manual), which reduces power to 50%. :::

Steering servo
MAIN4
Throttle (ESC input)
Rovers are configured using QGroundControl in the same way as any other vehicle.
The main rover-specific configuration is setting the correct frame:
Scroll down the list to find the Rover icon.
Choose Traxxas stampede vxl 2wd from the drop down list.
:::warning It is very important to do a mission composed only* of normal waypoints (i.e. no takeoff waypoints etc.) and it is crucial to set the waypoint height of every waypoint to 0 for correct execution. Failing to do so will cause the rover to continuously spin around a waypoint. :::
A correct mission setup looks as follows:
All of this is used except for the top plastic cover.
or other PX4-compatible remotes
(Deprecated)
For this particular mounting we chose to use the clip supplied with the rover to attach the upper plate. For this, two supports were 3D printed. The CAD files are provided .
:::note As documented in the Airframe Reference: . :::
Switch to the section in QGroundControl
Select the tab.
At the current time, PX4 only supports and MANUAL modes when a RC remote is connected. To use the mission mode, first upload a new mission to the vehicle with QGC. Then, BEFORE ARMING, select MISSION and then arm.
