Hvatač
Assemble
Model: Gripper A (gripper-a)
(robot will have to carry balls one by one) or
Model: Gripper B (gripper-b)
(the robot can load 4 balls at once and carry the 5th in gripper). Click on the links to see the instructions. The rest of the lesson will be based on
Model: Gripper B (gripper-b)
as the other is simple.
Join the assembly with the coupler using the screws delivered with the servo. 2 screws will be enough. Fix the coupler to the lift-servo, again using servo screws, 2 per side.
Potrebni elementi
Model: Gripper B (gripper-b)
, 1 kom.
Držači spremišta
Slide 4 container holders in.
Potrebni elementi
Model: Brick 1x2x2 (brick1x2x2)
, 4 kom.
Sklapanje spremišta
Attach a servo to container's main body. Use screws supplied with the servo. Put a matching disc on each axle and fasten it with a thicker screw supplied with the servo. Use the servo marked as "block" servo.
Potrebni elementi
Robot servo 0.6 Nm, 300º, dual axis, 6 V (mrm-rd-5606hb-300)
, 1 kom.
Model: Gripper container (gripperContainer)
, 1 kom.
Brana
Attach to the servo element that will stop the balls. Use 2 servo-supplied screws.
Spremište
Assemble container and fix it to container's holders.
Držač senzora za detekciju lopte
Fix the holder that will position reflectance sensor so that it can detect the type of the ball.
