# Watch This Robot Destroy Me at Beyblade Source: https://www.youtube.com/watch?v=dleOlb4zLEA Recap page: https://rapidrecap.app/video/dleOlb4zLEA Generated: 2026-02-28T14:05:14.82+00:00 --- ## Quick Overview The robot, nicknamed Roberto, ultimately defeats the human opponent in a Beyblade match, winning 7-3 by using a custom-built, motorized launcher that automates precise launch timing and placement, overcoming initial mechanical failures related to the cam system and gripper grip. **Key Points:** - The creator builds an automated Beyblade launcher robot named 'Roberto' to compete against human players. - Initial testing of the cam-based launcher revealed problems, including the Beyblade falling off or not reaching full speed, leading to multiple design iterations (0:04, 4:16). - The final robot design features a complex four-bar linkage mechanism actuated by a servo to move the launcher in a precise up-and-down motion to release the Beyblade (7:09). - The robot successfully launches the Beyblade, holding it on the launcher until the correct moment, which is a significant improvement over previous methods (6:18). - During the match against the human player, Roberto wins with a final score of 7-3 (10:37). - The creator notes that the primary issue was the interaction between the launcher gripper and the Beyblade's nub size, requiring many prototype gripper designs (4:18, 4:54). - The robot's head display changes expression based on its internal state, showing blue eyes when ready and orange eyes when in 'Hard Mode' (10:58). ![Screenshot at 10:37: The robot 'Roberto' secures a victory against the human player, indicated by the scoreboard showing Roberto leading 7-3, demonstrating the success of the automated launcher in a live match scenario.](https://ss.rapidrecap.app/screens/dleOlb4zLEA/00-10-37.jpg) **Context:** The video documents the process of building and testing a custom, automated Beyblade launcher robot designed to play the spinning top game better than a human opponent. The creator, who wears a captain's hat, details the engineering challenges faced, particularly concerning the mechanism that grips and releases the Beyblade from the launcher, leading to the development of a complex motorized system utilizing a cam mechanism and a four-bar linkage. ## Detailed Analysis The creator details the journey of building an automated Beyblade launcher robot named 'Roberto' (0:00). Initial concepts involved a simple double-launcher method (0:08) but proved unsatisfactory. The creator then sketches a complex mechanism involving a motor, spring, bearing, and a unique spiral cam system to control the launching motion (0:27, 0:57). Early prototypes of the launcher mechanism failed because the Beyblade's grip was insufficient, causing it to fall off (4:16, 5:35). The creator then iterates to a more complex, multi-servo design mounted on a stand, which utilizes a four-bar linkage to control the launch angle and position (7:09, 7:22). Despite overcoming initial failures like jittering and component breaks (5:25), the final version successfully launches the Beyblade and maintains contact until the top is spinning fast enough to be released reliably (6:18). The video culminates in a demonstration match where Roberto defeats the human opponent with a score of 7-3 (10:37). The robot's expressive red head display shows blue eyes when ready and orange eyes when in a harder mode (10:58). ### Initial Concept & Cam System - Double launcher method rejected - Concept sketches reveal a cam system driven by a motor to push/release the Beyblade (0:27) - Cam system initially causes jittering and fails to reliably launch (5:57) ### Final Robot Design - New vertical launcher design using a four-bar linkage actuated by a servo arm (7:09) - Robot body is white with a red, expressive face display (10:58) - Custom launcher gripper design was critical to success (4:15) ### Testing and Results - Early tests showed Beyblades falling off prematurely or failing to launch correctly (4:11, 5:35) - The final design succeeds in holding and launching the Beyblade with precise timing (6:18) ### The Match - Roberto (Robot) competes against 'Humans' - Final score is Roberto 7, Humans 3 (10:37) - The robot's complexity is noted, but the final launch mechanism works effectively (6:07) ![Screenshot at 0:08: The initial physical test setup showing the dual launcher method being used before moving to the automated robot design.](https://ss.rapidrecap.app/screens/dleOlb4zLEA/00-00-08.jpg) ![Screenshot at 0:31: Close-up on the initial CAD sketch detailing the components of the cam-driven launch mechanism, including the spring, motor, and bearing.](https://ss.rapidrecap.app/screens/dleOlb4zLEA/00-00-31.jpg) ![Screenshot at 0:44: CAD animation showing the first motorized launcher design where the cam follower pushes the launch rod up and down \(0:55\).](https://ss.rapidrecap.app/screens/dleOlb4zLEA/00-00-44.jpg) ![Screenshot at 7:14: Close-up of the final, complex blue and white 3D-printed launcher arm mechanism successfully touching the spinning Beyblade to release it.](https://ss.rapidrecap.app/screens/dleOlb4zLEA/00-07-14.jpg) ![Screenshot at 10:58: The final robot, 'Roberto,' featuring a red box head with glowing blue eyes and a smiling face display, showing it is operational.](https://ss.rapidrecap.app/screens/dleOlb4zLEA/00-10-58.jpg)
