Dear Support,

the robot starts moving on its own (Sabertooth 2×25) what would be reason for this and how I should avoid this? This can happen example when need to help robot pushing it or it goes downhill.

The connection is from batteries (two batteries in series)to the main fuse to the main switch to the Sabertooth where are connected two DC gear motors and remote control receiver.

Without know more details, this is difficult to answer. Sounds like you are trying to run in RC. Send pictures of your wiring.

In general: improper dip switch settings, ground loops, dirty power, electrical noise, etc. can cause this. Look at our support pages for good practices.

In RC mode it could be trimmed improperly. Also make sure you do not move the joysticks until its fully bound. It tries to calibrate when binding. Make sure the RC receiver is not close to motors, batteries, or power wires.

In Serial Mode, if you do not send the correct packets…
