Looking for a quick and easy way to attach a wheel to a servo for a wheeled robot? Here's the answer! This custom-molded wheel is designed to fit to most servo hubs (excluding Hitec), and give solid traction to your robot. The hubs dimension out at 65mm (just under 2-5/8"), by 7.62mm wide (0.3"). Adding one molded-on thermoplastic silicone "tire" to the hub makes the rolling diameter 67mm (2-5/8"). Each wheel comes with ONE black special-grip tire. Compatible with GWS and Parallax continuous rotation servos.

The SparkFun Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state, the Servo Trigger is able to tell an attached servo motor to move from position A to position B. To use the Servo Trigger, you simply connect a hobby servo and a switch, then use the on-board potentiometers to adjust the start/stop positions and the transition time. You can use a hobby servos in your projects without having to do any programming!

This mechanical claw is made from metal and is pretty heavy-duty. It is great for robotic projects. The mechanism features brass sleeves in the joints which make them more rigid and less likely to come loose. The claw opens to about 2" and depending on the servo motor used, it can pick up some relatively heavy objects. The new spring-loaded clutch helps protect your servo gears from damage and also increases the gearing to 2:1, allowing the servo to act over its entire range and provide more gripping power!

The Rollarm Kit for Arduino is designed for mass hobbyists to learn robot arm control. With the open source MCU Arduino UNO and a servo expansion board, the robot arm is easy to use and full of fun. You can control its four axes by the 4 potentiometers on the handle, as well as make them move on your computer. In addition, it can memorize the movements it's made and repeat again and again, making it a great tool for repeated tasks.
