2WD 2 Wheel Transparent Robot Motor Chassis Kit for Arduino

This is 2WD 2 Wheel Transparent Robot Motor Chassis Kit for Arduino. The mechanical structure of 2WD 2 Wheel Transparent Robot Motor Chassis Kit for Arduino is simple and easy to install. This kit is the tachometer encoder and Can be used for distance measurement, velocity. Can use with other devices to realize the function of tracing, obstacle avoidance, distance testing, speed testing, wireless remote control. Features: Motor power supply is 3V~6V. All the parameter above is tested without load Please notice that the wooden outside is just a PROTECTION FILM. You need to TEAR OFF the yellow-brown protective paper outside the car chassis, and you will see the transparent clear car chassis inside. Please allow 1-2cm errors due to manual measurement Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same Specification: Color: Transparent Watercolor For Bo Motor (Voltage): (Voltage, Current, No-load Speed, Load Speed, Torque, ) @ DC 3V: 160mA, 120 rpm/min, 100 rpm/min, 0.45 kg.cm @ DC 6V: 220mA, 200 rpm/min, 175 rpm/min, 1.0 kg.cm @ DC 7.2V: 250mA, 250 rpm/min, 210 rpm/min, 1.5 kg.cm Reduction Ratio: 0.075 Noise: less than equal 65dB Motor Size: 65mm x 18mm x 22mm(L*W*H) Package includes:  1 x Car Chassis 2 x DC Gear Motor(1:48) 2 x Car Tire 2 x Velocimetry Code Wheel 1 x Universal Wheel 1 x Battery Container(battery is NOT included) 4 x M3*8 Screw 8 x M3 Nut 8 x M3*6 Screw 4 x M3*30 Screw Note: Pictures are just for representational purpose and the color may vary
