Chapter 18. the SNATCH3R: the autonomous robotic arm
Throughout the previous chapters, you’ve learned a great deal about programming EV3 robots. Now you’re ready to build and program the more sophisticated robots in this part of the book. This chapter will teach you to build and program the SNATCH3R, a robotic arm that can find and pick up objects, as shown in Figure 18-1.
You’ll first create a program that lets you control the robot remotely so you can test its mechanical functions, and then you’ll program it to find and grab the infrared beacon autonomously. You’ll use data wires and variables to make the robot scan its surroundings so that it can find the beacon from up to 2 meters (6 feet) away, even if it’s behind the robot.
