1977 – IPM Six-Legged Walker with Laser Scanning – Okhotsimski et al (Soviet)

The insect-like walkers were referred to as "cockroaches".

In the early 70s, at the Institute of Applied mathematics (IPM) of the Russian Academy of Sciences in Moscow, a six-legged walking machine controlled on a base of a mathematical model of motion control was developed. The machine motion and the terrain were rendered on a display. Motion control algorithms were developed for a walking machine on rugged terrain in both automated and operator control modes. The problems of control were also considered for a dynamic model of a statically stable walking machine (Okhotsimski & Platonov, 1973, 1976).

In this small video compilation there is a few seconds of the simulation under joystick control.

The first six-legged machine was equipped with a laser scanning range finder and is connected with a two-computer system. The walker could move around isolated obstacles which were detected remotely by a scanning distance-measuring system, and could climb over obstacles (see Fig. 2.9).
The parameters of the machine are the follows: body length 0,6 m, body width 0,25 m, weight 56 kg, length of leg 0,4 m, velocity 0,2 m/s (Okhotsimski & Platonov, 1976; Okhotsimski et al., 1978).

Okhotsimsky is on the right.

There was a 'family' of these walking machines. See also "Masha" and another of Gurfinkel's walking machine here (not yet posted).

1976 – “Masha” Hexapod – Gurfinkel et al (Soviet)

Masha being used in some force-feedback experiments. The experiment here to feed a cylinder into an inclined funnel.

See Devjanin-Schneider paper here.

The above three images show experimentation by Gorinevsky.  His paper is available here.

Gorinevsky produced a video of the walking machine. After many media transformations, the quality is poor. See here.  

The above  image, I believe, is incorrectly attributed to Bessonov.

Note also the due to incorrect spelling from the old “Walking Machine Catalog”, some sites know this walking vehicle as “Mascha”.

“Masha”, a hexapod walking vehicle an control system designed at the Institute for Mechanics at Moscow State University and at the Institute for Problems of Information Transmission at the USSR Academy of Sciences.
