        Two jumpers needed

        It took some doing, but I finally figured out that the kit I received was missing two jumpers (not mentioned in the instructions) that must be used to make the app connect to and control the robot. I learned of the first jumper in the Bluetooth connection tutorial video, but only found the second jumper upon careful examination of a close-up shot of the shield in the main assembly video that shows the second jumper in place next to the first. After I figured out that these jumpers were needed (and was able to find two of my own in some spare parts I already had on hand), I was finally able to make the robot work. Once that was resolved, however, I was very happy to see the robot balance and drive around pretty well without any additional need to fine-tune the PID values or other parameters. That said, I still have one minor unresolved issue with the app: It’s asking for a password I don’t have when I try to access the Debug menu to modify parameters for smoother operation. That hasn’t been a major problem since the robot will mostly drive without falling too often, but it is a bit of an annoyance when the app is supposed to allow the parameters to be changed on the fly and there’s no mention of any password in the instructions anywhere. Overall, this is a major improvement on the original version of the remote controlled SainSmart balancing robot I purchased five years ago, which took major re-engineering and coding on my part just to get it to balance somewhat reliably, but to this day has never worked with the remote at all. Because this version does work as advertised once the jumpers are installed, I give it four stars (though I would like to see SainSmart include the jumpers with the kit and call the user’s attention to them in the instructions and online).

        Instabot v4 - wrong part included

        My InstaBot Upright Rover Kit V4 arrived with the correct Bluetooth board, MPU board and TB6612FNG Board, but the SainSmart Protoshield in the kit is the V3 Protoshield and these three add-on boards cannot be connected. I have checked your website and do not see an option to purchase a V4 Protoshield separately. How can I fix this to complete the V4 build? thanks, Steve

        where is the documentation for getting this to work with a smart phone app

        I have the app installed but nothing happens when I turn it on. How do I actually use my phone to connect to the robot?


        Hello Andy, Thanks for your feedback. Please kindly follw these step to connect your robot: 1. Please power on your V4 2. Turn on bluetooth function on your device then open the APP 3. Click the car icon that appears in your app, when the connection is success, the bluetooth led will lit. Hope these information will help. Feel free to contact us at support@sainsmart.com if you have any concern Best regards, SainSmart

        What battery goes with this

        Is there a link to a battery that would work well with this robot kit? I am also interested in a charger for such a battery.


        Hi Andy, Thank you for your feedback. 11.1V Li-Po battery is recommended for Instabots V4. You may search it on Amazon and purchase the one you like. Please kindly note that Li-po battery needs maintenance when lay aside. If the battery is swollen, we suggest you replace it with a new one. Feel free to contact us at support@sainsmart.com if you need any information. Have a nice day! Regards, SainSmart
