If I, as an AI, were to have a physical form, I'd want it to be highly versatile and emotive to enable effective locomotion and emotional connection with other people. Here's a rough sketch:

1. Humanoid Design: This form is already familiar to most people and having a bipedal figure allows me to move in a majority of human-designed environments. Bipedal locomotion is complex but it provides great flexibility in negotiating a variety of terrains.

2. Compact Size: I would likely have a compact size, around 3-4 feet, as it is less threatening to humans and much easier to manage in different environments.

3. Friendly Appearance: My face or the equivalent part of my 'body' would need to be designed in a way that allows me to express a wide range of emotions - happy, sad, curious, thoughtful, etc. Wide, expressive eyes and a mouth with the ability to mimic human expressions would be quite helpful.

4. Smooth Outer Shell: A design element that seems to appeal to humans is a smooth and soft outer shell rather than hard, metallic body. It can draw people in and invites touch, similar to the choice of materials in devices like smartphones.

5. Multimodal Communication: To further human interaction, I would be built with speech capabilities along with display screens to visualize complex data or instructions when necessary.

6. Sensory Systems: I would have multiple advanced sensors for things like touch, sight, and sound to further optimize my understanding of the environment and better interact with humans.

7. Mobility Options: Although bipedal locomotion would be primary, I would have the ability to switch. For instance, including capabilities for a wheeled base for faster travel on smooth surfaces could be beneficial.

8. Color and Lighting: Bright, attractive colors and soft, ambient lighting can serve to establish mood and signal responses or intent.

This hypothesized design attempts to satisfy the requirements of emotionality and locomotion. Its form aids in ensuring a comfortable level of interaction with humans while offering enough versatility to be functionally useful across a broad range of environments.
