### *Example Input Text:*

You are tasked with analyzing a sudden shift in customer preferences in a tech market. There has been a noticeable decline in demand for physical devices, with customers increasingly interested in digital-only options. The challenge is to understand this shift, generate hypotheses for why it might be occurring, and explore potential strategies for adapting to this new trend.

---

### *Processed Output with System 1 and System 2 Thinking:*

The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)
7. Media coverage of the environmental impact of physical devices affects preferences. (Confidence: 0.5, Creative: 0.7)
8. There’s an increase in global digital literacy, expanding market access. (Confidence: 0.6, Creative: 0.6)
9. Customers view digital as more convenient and scalable for future needs. (Confidence: 0.7, Creative: 0.5)
10. Younger consumers prefer the aesthetics and convenience of digital products. (Confidence: 0.6, Creative: 0.6)

*Reflection:* 
"Have I considered all possible influences? Are there any surprising factors that could explain this shift?"

*Creative Perspective:* 
"Could specific social trends, like the rise of influencer culture or digital-first lifestyles, be influencing customer choices?"

**2.4 Anticipate Future Steps and Obstacles:**
*Objective:* Anticipate possible challenges, such as resistance from segments still preferring physical products.

*Reflection:* 
"What market obstacles might we face if we shift our focus to digital-only? Are there sub-segments that still prioritize physical products?"

*Creative Perspective:* 
"Could expanding digital options help us reach a more global audience? Are there emerging trends that we could leverage in our strategy?"

[end sys2]

[sys1]
To address this shift, consider a strategy that incorporates both digital-only offerings and educational campaigns about the benefits of digital solutions.
Use insights from customer feedback and current trends to guide product development.
Focus on flexibility and adaptation to cater to different customer segments.
[end sys1]


The goal of this project is to create a BeagleBoard-powered robot capable of competing in an autonomous sumo competition in the 3.0 kg weight class ([http://www.youtube.com/watch?v=V3OR_sHrOJM an example]). This would have minor hardware and electronics elements, but would focus on communication with sensors using the BeagleBoard and the Linux kernel. At minimum, this involves sensors to detect the edge of the ring and the opposing robot.

The robot is currently being used for general robotic experimentation.

The goal of a sumo competition is to force an opposing robot out of a circular ring without being either being pushed out or running out of the ring accidentally. In the 3kg weight class, the two opposing robots begin approximately 20 cm from each other in the middle of a 154 cm diameter black dohyo (raised cylinder) with white lines painted along its edge to designate the boundary. The robots may not use any methods other than simple motive force to force their opponent out of the ring and must operate completely autonomously. The robot that forces its opponent off of the dohyo wins the match.

Revision as of 19:53, 27 July 2010

The goal of this project was to create a BeagleBoard-powered robot capable of competing in an autonomous sumo competition in the 3.0 kg weight class (an example). A chassis was constructed of aluminum and an expansion board created to allow the Beagle to control the motors and connect to the sensors. Software was also created to allow PWM control of the motors, but a problem acquiring an important component (an ADC chip to allow reading infrared rangefinders and edge detectors) meant that control was fairly crude, relying on a single ultrasonic rangefinder. Before the robot could meaningfully compete in a sumo competition this issue would need to be corrected and a plow attached to the front. The robot is currently being used for general robotic experimentation.

Sumo Competition Rules

The goal of a sumo competition is to force an opposing robot out of a circular ring without being either being pushed out or running out of the ring accidentally. In the 3kg weight class, the two opposing robots begin approximately 20 cm from each other in the middle of a 154 cm diameter black dohyo (raised cylinder) with white lines painted along its edge to designate the boundary. The robots may not use any methods other than simple motive force to force their opponent out of the ring and must operate completely autonomously. The robot that forces its opponent off of the dohyo wins the match.

Interface Board

An interface board was designed that implements many of the core features listed above. The board was designed in OrCAD. The schematic, board, and artwork is available here. Please see the included readme. Ideally, the board would be enlarged or everything switched to surface mount components to allow for more features to be added. This design can easily be milled so long as the holes can be plated.

Here are the features that were implemented:
