This is a robot drive wheel we had made specifically for us. It does not have a bearing. It is 6 inches in diameter and 2 inches wide. It's a solid foam core with rubber treads and outer layer. The steel rim is painted black with a 4 bolt pattern so you can easily mount it to a flanged hub.
This is a ROS programmable autonomous SLAM robot prebuilt kit that can be controlled via Gamepad. The MarvelMind IPS (Indoor Positioning System) provides indoor navigation. ODROID-XU4 SBC provides the most flexible platform possible.
This ATR robot uses custom length sides and 10 inch tires. We have included everything to make it ready to run including batteries, controllers, chargers, etc.
