TOPO IV Specification Sheet

Topo IV was a prototype TOPO unit that only made it in the early design stage before being scrapped.

The main specification sheet was mailed out during the final days of the company in 1985. The only part that was built was the sensor belt.

Build[edit | edit source]

The robot took multiple cues from B.O.B, mainly all of the same sensors. It seems like it would use the Topo III shells, but it also has the option for a rotating head, which was not possible on the Topo II shells without heavy modification. An arm is also stated in the sheet, possibly something akin to BOB/XA's Androlift.
