Ultrasonic Obstacle Avoidance Car Tracking Ranging Robot …, Mackay

Parameter Working voltage 5VPCB size 120 73mmPower supply mode 4 AAA batteries package are not included Working current no load less than 300mA the motors are working but not walking The universal wheel version reduces the walking resistance of the car saves power and lasts longerFeatures 1 Using high quality materials the quality is guaranteed2 Ultrasonic distance measurement and obstacle avoidance automatically rotate or back to avoid obstacles when encountering obstacles3 The digital tube displays the current obstacle distance in real time up to 5 meters4 Introduce a new simulation design concept to make the circuit board more like a car chassis a dedicated motor drive chip control the forward and reverse rotation of the motor and flexibly control the car s forward backward in situ rotation and other actions the STC single chip control system is closer to the people5 A wide range of applications training hands on abilityPackage Include 1x DIY Car Kit
