Interactive 3D Model
Robot Front Half
For the front half of the robot, there are two pick-and-place robotic arms, each equipped with a laser sensor on the gripper to automate seedling pickup when they are correctly positioned. After picking, the wrist lifts using a rack and pinion mechanism, and the arm base rotates to place the seedling into one of four storage compartments inside the robot. The same mechanism works in reverse when the robot places the seedlings back on the ground.
The gripper is capable of pulling up to 1 kg of payload using a 35 kg servo, which is more than suitable — each seedling weighs approximately 400 grams.
In total, the robot can pick and place 8 seedlings in just 15 seconds.
Robot Back Half
For the back half of the robot, it includes the ball picking and shooting mechanisms, as well as two electronics cages — one on the left and one on the right. The robot moves toward the targeted ball, extends an arm, and uses a flywheel to suck the ball into the shooting area. “Sorry, I can’t show the picking mechanism due to corrupted files — I’ll try to redesign it in the future.” Once the ball is in position, the base gear rotates left or right to aim the shooting mechanism toward the target. The robot then shoots by spinning the flywheels — one at the front and two at the back — all driven by a single brushless motor connected via a timing belt.
