RC vehicle inspired by Mars rover Curiosity. Parts are printed on 3D printed. Main Processing Unit is Ardunio Mega. For moving used 6 9g servos with metal gear and edited for 360 rotating, for steering used 6 standart 9g servos.
Control is standard 4 channels. Power by 2S or 3S lipo battery - 6V SBEC.
------ Rover Mk II ----
simple instruction: http://www.mochr.cz/index.php?id=rc-rover ( wait for complete...)
Arduino files are in the RAR archive.
6x 9g servo (TG9e, TowerPro SG90)
6x 9g servo with metal gear (TGY-5009M)
Arduino Mega 2560
SBEC Lipo 5/6V 5/6A for 3S lipol
3S Li-pol about 1300mAh
12x servo extension cable (10-30cm)
12x resitor 2.2K ohm
green LED 3mm
red LED 3mm
yellow LED 3mm
3x resistor 160 Ohm
42x screw M2x6
6x screw M2.5x6
2x screw M3x25
8x screw M3x6
8x nut M3
4x nut M2
4x white LED 5mm
4x red LED 5mm
RC TX and RX
connector to Arduino
3D printed parts
After build Rover is needed to center the servos.
Upload this file to Arduino.
// 2 - 7 for all steering servos
// 8 - 13 for all wheels servos
int pin = 13;
check all servos with serial monitor for center position. My value is about 1300-1500. Value write to this file , and upload to Arduino.
// Data from calibration servos - center position of servo
int W1_center = 1350;
int W2_center = 1390;
int W3_center = 1360;
int W4_center = 1370;
int W5_center = 1435;
int W6_center = 1355;
int S1_center = 1500;
int S2_center = 1480;
int S3_center = 1420;
int S4_center = 1410;
int S5_center = 1480;
int S6_center = 1480;
Now you need center signal from RC. Connect RX to PCB and Arduino connect with PC. Control stick on TX set to neutral. Serial monitor write some values. Copy this values to Excel and make average value ( about 50 values is OK). Repeat to second channel.
// calibration RX signal
// calibration RX signal
Servo with metal gear use to wheel. You must modifying to countinous rotating. Cut of potentiometer, add 2 resitors, cut of pin on tooth wheel.
