When I bought the home version of Mindstorms EV3, I was disappointed that the gyro sensor was not included. So I bought the gyro sensor, and also the ultrasonic sensor, separately. Using the elements from the home EV3 set and the 2 sensors I made this model. (utrasonic sensor is optional) gyroboyharrie, a shooting gyroboy Control via colored bricks, infrared remote or Android phone.Even infrared beacon following is included. In case the optional utrasonic sensor is used it will avoid objects.

You've got a point there. Changed the design to use small 2m axles instead of the pegs.

In LDD I would like to insert a peg for only half a unit, but it will refuse. E.g. in the following picture I want to insert the 2 pegs only halfway into the motor. Attached the .lxf file. half_peg_insert.lxf
