This is the second prototype and the video shows how to solve Mission
M13. See the full playlist here.
This version is an improvement over the first prototype in several ways:
The driving motors are turned so forward in the EV3 software translates into forward motion on the robot.T
he footprint is smaller, making it easier to navigate on the mat.
The caster wheels have been replaced with bevel gears, resulting in more accurate driving when going straight.
The M-motor is now directly connected to the lifting mechanism which makes it easier to position and reset.
There are now two lifting sockets on the lower lifting assembly.
The color sensor is built into the robot base and is close to the center of the front of the robot, making it easy to program a line follower.
