Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional robotic picking methods are used, then the device can perform basic picking tasks, but it requires extensive human intervention when encountering failures
Solution Approach 1:
The system implements feedback loops where the robotic device observes failed picking attempts, analyzes the failure causes through computer vision, adjusts its strategy, and retries. This closed-loop learning process enables the system to improve its performance autonomously without requiring human intervention for each failure.
Solution Approach 2:
The robotic device performs self-training and self-improvement by automatically learning from its own failures. Through self-supervised learning and reinforcement learning mechanisms, the system autonomously develops better picking strategies without external training data or human guidance, effectively serving itself to overcome limitations.
2Adaptability or versatility
If the robotic device attempts to pick items from varied arrangements, then it can handle diverse scenarios, but it encounters failures due to physical constraints and material properties
Solution Approach 1:
The system dynamically adapts its picking strategy based on real-time observation of item arrangements, materials, and environmental conditions. Rather than following fixed protocols, the robotic device adjusts gripper force, approach angles, and timing dynamically to accommodate varied scenarios while maintaining reliable performance.
Solution Approach 2:
The robotic system changes operational parameters such as gripper force, speed, and positioning based on detected item properties like material, shape, and fragility. This parameter adaptation enables the system to handle diverse item arrangements reliably by optimizing picking conditions for each specific scenario.
3Adaptability or versatility
If deep neural networks are used for decision-making, then the robotic device can learn complex patterns, but it requires extensive training data and time
Solution Approach 1:
The system uses self-supervised learning where the robotic device generates its own training data from actual picking attempts and failures. By learning from self-collected experience rather than requiring externally prepared datasets, the system reduces training time and data requirements while maintaining strong adaptability to new scenarios.
Solution Approach 2:
The system employs transfer learning and few-shot learning approaches where deep neural networks are pre-trained on general object recognition tasks and then fine-tuned with minimal task-specific data. This partial training strategy reduces the excessive data and time requirements while preserving the network's ability to learn complex patterns.

AI summary
Various embodiments of the present technology generally relate to robotic devices and artificial intelligence. More specifically, some embodiments relate to an artificial neural network training method that does not require extensive training data or time expenditure. The few-shot training model disclosed herein includes attempting to pick up items and, in response to a failed pick up attempt, transferring and generalizing information to similar regions to improve probability of success in future attempts. In some implementations, the training method is used to robotic device for picking items from a bin and perturbing items in a bin. When no picking strategies with high probability of success exist, the robotic device may perturb the contents of the bin to create new available pick-up points. In some implementations, the device may include one or more computer-vision systems.
