So it acted like the screw heads were already stripped and so its stripped them further against the nylon nuts you were screwing against. The screw for the arm base plate servo wasnt long enough to reach the servo motor. The boards i have are also having issues with Arduino. Quite a few different errors from the software on the boards. I’ve waited a while to get this and disappointed in the end result. ## Frequently Bought Together - KEYESTUDIO 4WD Bluetooth Smart Car Robot Arm Building Starter Kit for Arduino ，for Uno R3 Programmable Robotics Coding Kit DIY Set for Student Adults 15+ - Freenove Hexapod Robot Kit with Remote Control | Arduino Based Project | Raspberry Pi | Spider Walking Crawling 6 Legged | Detailed Tutorial | Android APP | Wi-Fi Wireless RC 2.4G Servo --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/275547328-keyestudio-4wd-bluetooth-smart-car-robot-arm-building-starter-kit](https://www.desertcart.hr/products/275547328-keyestudio-4wd-bluetooth-smart-car-robot-arm-building-starter-kit) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-22*
