Helloit's 2023 and there are still no announcements on possible accessories for improving the robomaster s1.  thank you for the false advertising....
Have people in the community to add unofficial accessories such as a clamp or mechanical arm to the s1?

Hi, Niko84. We're sorry for the inconvenience. The RoboMaster S1 cannot use the RoboMaster EP (Core) accessories, and functions of these accessories such as the robotic arm in the RoboMaster app cannot be used even if a robotic arm is mounted on the RoboMaster S1. The RoboMaster S1 and RoboMaster EP (Core) are different in terms of port configuration and hardware. The RoboMaster S1 cannot be used with the accessories added to the RoboMaster EP (Core), nor can it use the functions of these accessories.
