My first motorized truck, equiped with steering, drive and pneumatic arm with internal compressor.
Steering is operated with a XL motor (8/24, 8/24 reduction) placed on the front of truck. A XL motor place in center of frame drives the rear wheels (12/20, 12/20, 12/diff reduction). Next a M motor drive a worm gear and a 8t on the turntable to rotate the arm. One other M motor placed on the left operates the two internal compressor. To finish, pneumatic switchs are placed on the right and enable to control the pneumatic arm (composed of 3 pneumatic cylinders).
