Robotis Mini
Save 20%The ROBOTIS MINI is a programmable miniaturized humanoid robot which allows you to integrate concepts explored with the DYNAMIXEL (XL-320) actuators, OpenCM9.04, an Arduino-based IDE Board, and Bluetooth Connectivity.
Overview
The ROBOTIS MINI can be programmed using RoboPlus Task (R+Task), a graphical, drag-and-drop programming tool based on C++.
You can also create complex motions or choreography using RoboPlus Motion (R+Motion), a motion-editing tool.
You can download the free ROBOTIS MINI APP on your Android or iOS smart device which comes with pre-programmed moves. Students can explore 3D Printing concepts with the ROBOTIS MINI by 3D printing their own frames for customization!
The ROBOTIS MINI offers a challenging but fulfilling building experience.
The kit includes a fully-colored assembly manual that not only provides detailed assembly instructions, but also provides building tips.
Features:

VarSpeedServoRA4M1 is a library for Arduino that enables precise control over servo motors, including speed, position, and movement sequences.
In robotics and several other disciplines, PID (proportional-integral-derivative) control is a way for systems with closed-loop feedback to adjust themselves according to sensor data without overshooting the target. Drones, for example, use PID control to remain stable without wild oscillations caused by over-correction. But implementing PID control can feel overwhelming, so Adam Soileau from element14 Presents built a simple robot for some experimentation. This robot’s only job is to drive forward until it sees a wall, then stop at a specific distance from that wall. That isn’t hard to achieve when a robot is moving at slow pace, because the code can tell the robot to stop moving the moment it reaches the target distance. But when moving fast, the robot has to take braking acceleration into account and that is much harder to predict. PID control is perfect for this situation, because it adjusts motor output in real-time according to the incoming sensor data. In this case, that sensor data comes from an ultrasonic rangefinder mounted to the front of the 3D-printed robot. An Arduino UNO R4 Minima board receives that data and controls the robot’s two motors through H-bridge drivers. That hardware is very straightforward so that Soileau could focus on the PID control. Tuning that is all about balancing the three constant values to get the desired performance. Soileau spent some time working on the Arduino sketch to get the PID control integrated and was eventually able to make the robot act like it should. If you’re interested in using PID control in your next robotics project, then Soileau's video should help you get started.
