Problems solved by technology

However, the joint drivers of this kind of manipulator are in the state of energy consumption when performing detection. Although a motor with a permanent magnet brake can be used to maintain its detection posture, it needs to consume more electric energy to overcome the permanent magnet brake when the manipulator rotates.

Embodiment

[0025] Example: attached figure 1 For the detection state when the mechanical arm 10 lifts the stereo camera 21, the locking pin 18 provided on the wrist joint 16 is inserted into the locking device 40 through the rotation of the body joint 13′, the shoulder joint 14′, and the elbow joint 15 of the mechanical arm 10. In the lock groove 43, the rotation of the wrist joint 16 drives the lock bolt 44 to lock the lock pin 18 in the lock groove 43, so that the forearm 11, the rear arm 12 and the locking device 40 form a triangular stable structure. According to the stability of the triangle, as long as the locking pin 18 on the wrist joint 16 and the locking device 40 are kept reliably fixed, the positions of each joint of the mechanical arm 10 relative to the vehicle body 31 are kept fixed. In order to increase the lifting height of the stereo camera 21, The triangle formed here is an isosceles triangle.

Abstract

The invention discloses a multifunctional integrated type mechanical arm for a planet exploration vehicle. The mechanical arm is provided with four rotational joints; and a three-dimensional camera with a two-dimensional rotary table is arranged at an elbow joint of the mechanical arm. By a triangle stability principle, the mechanical arm and a locking device form a triangular stable structure, and the mechanical arm and a mast for lifting the three-dimensional camera are combined into a whole, so that the mast for lifting the three-dimensional camera is eliminated, a mechanism is simplified,the weight is reduced, electric energy consumption required by the mast is eliminated, and the energy efficiency of a Mars exploration vehicle is greatly improved.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a multifunctional mechanical arm for a planetary exploration vehicle. Background technique [0002] At present, the two hot spots of space exploration are the moon and Mars. Among them, the United States has achieved manned landings many times in the 1960s, and China has launched "Chang'e 1" and "Chang'e 2" in 2007 and 2010. "The lunar probe has realized the exploration around the moon, and the next step "Chang'e 3" will realize the unmanned probe vehicle to land on the moon. [0003] Exploring Mars is of great significance to understanding the origin of life on Earth. China is currently developing a high-thrust launch vehicle for Mars exploration. The first Mars probe "Yinghuo-1" developed by my country will work with Russia's "Phobos" probe. Fly to Mars in 2011 on a Russian Forbes rocket. Since Mars is farther away from the earth, it takes about half a year to launch from the earth to Mars....
