Robot 4x4 car with arm Arduino controlled

thingiverse

This is a robotic car with arm controlled by Arduino. All printed in PLA except wheel treads, printed using flexible material. Printed with the following settings: 0.3mm layer thickness. Most parts need little or no support. The parts are assembled using M3 or 1/8’’ bolts with 2 nuts for the movable part of the arm. And, 3mm self-tapping screws for electronics and fixed parts. Need 4 608zz bearings. Electronics: Arduino Nano, 16 Channel PCA9685, HC-05 Bluetooth module, BMS 2S Equalizer 8,4V 10A, 4 I/O Logic converter, Step Down LM2596, Step Up MT3608 with MicroUSB, 2 IR Proximity Sensors and SR-04 ultrasonic sensor. Power source: 4 x 18650 3.7V Li-ion batteries. Motors: 4 x MG996R Continuous Rotation Servo (Wheels) and 5 x MG996R Servos (Arm). Accessories: Pushbutton, Battery terminals and DuPont Female-Female Cables Among the Thing files, there in a PDF with an schematics and the Arduino code used to control the robot. The robot can be controlled with an Android App from App inventor (http://ai2.appinventor.mit.edu/#5846191894560768). This App is not multitouch, however, there is a multitouch App within the Thing files compiled using a multitouch extension in App inventor.
