In this thrilling episode with Jeff the G1, we witness the incredible capabilities of robotic technology. By utilizing a keyboard, Jeff demonstrates the precise control over the robot's hand movements, showcasing the ability to move in various directions. However, the challenge arises when attempting to control all seven motors in the robot's arm due to limitations in the SDK, leading to the need for joint-level control rather than Cartesian control.
The real excitement kicks in when Jeff sets his sights on a monumental task: retrieving a $65,000 bottle of bubbly water from the kitchen using the robot. Despite the advancements in locomotion and occupancy grid, the lack of high-level control for the hands presents a significant hurdle. Jeff contemplates the use of reinforcement learning and simulation to tackle this complex problem, highlighting the intricate balance between supervised and unsupervised approaches in training the robot.
Undeterred by the challenges, Jeff embarks on a unique strategy of training the robot through manual demonstration, showcasing the power of ground truth data in teaching the robot various actions. This method proves surprisingly effective, requiring minimal samples to achieve impressive results. Alongside these technical feats, Jeff shares his astonishment at the widespread interest in G1 robots, with many individuals, including non-programmers, expressing enthusiasm for these humanoid machines. Through meticulous testing and adjustments, Jeff refines the robot's capabilities, addressing issues such as occupancy grid accuracy and battery percentage display, while also implementing features like faster walking speed and an emergency stop function for enhanced control.
