Lack of imagination or technological lag:

A cube design with wheels on each face, or movable ones.

A sphere with helper wheels, unscoopable.

A killer bot inside the flipped bot.

An EMP bot.

Good grief, people, use your imagination and quit whining/

Yup, the sphere was my preferred design. Something that would roll without external protrusions (very heavy controlled counterweight inside), with powered spikes to snap out & in for damage. Wedge would do nothing, while the weight and spikes tear it up.
