Hi Joel,
What’s kind of batteries do you use?
It is suggested to use rechargeable Li-ion battery or rechargeable nickel-metal hydride, nickel-cadmium which can be bought from amazon or local shop. Or Alkaline battery with good quality like Energizer, DURACELL but these non-rechargeable batteries may not last long since ranger is a high power robot which consume the power in the batteryquickly.
Once still doesn’t move after changed the batteries recommended, please upgrade firmware for the robot have a check.How to Upgrade Firmware for Ranger.zip (358.3 KB)

Hi Joel,
Yes, that is the instruction to upgrade firmware.
If you control the Ranger robot with Makeblock APP, I think you can reset default program for the ranger with latest version mBlock 3.4.5, please refer to this instruction insteadHow to Reset default program for Ranger.zip (411.1 KB)
Once still the same issue after you tried all above, please kindly take a video to show the issue on the Ranger robot.
